First Layer Issues<\/h2>\n\n\n\n<p>The first layer of your print is probably the most important layer. As the foundation to your whole print, it is essential in providing proper adhesion to the build plate.<\/p>\n\n\n\n<p>Many common 3D printing problems stem from a poor first layer. There are a couple of things that can go wrong when printing your first layer.<\/p>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-144690\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Nozzle too close to the bed<\/h3><div id=\"ac-144690\" class=\"c-accordion__content\">\n\n<p><strong>Signs that your nozzle might be too close to the bed:<\/strong><\/p>\n\n\n<ul class=\"wp-block-list\"><li>Printed line is way thinner than desired. It might get so thin it turns transparent.<\/li><li>Excess filament is squished upwards at the edges of the current printing line creating a rough surface and wavy patterns. (You can feel the roughness when touching it carefully even during the print).<\/li><li>Filament is getting torn off the bed when the next neighboring line is printed.<\/li><li>Finished prints are hard to remove from the print bed.<\/li><\/ul>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<ul class=\"wp-block-list\"><li>If your nozzle is too close to the bed, there is not enough space between the nozzle and the bed to extrude the proper amount of filament. Excess filament is either squished upwards between individual printed lines or isn\u2019t extruded at all creating additional pressure in the HotEnd.<\/li><li>Excess filament that gets squished to the sides and upwards might get torn off the bed on the next pass by the nozzle destroying adhesion and making the top of your first layer very rough to the touch.<\/li><li>Excess filament might also get picked up by the nozzle and might drip back on your print later. This is especially common for PETG.<\/li><li>If filament backs up in the HotEnd because it cannot get extruded due to the nozzle being too close to the bed, your extruder might even get jammed and start clicking.<\/li><li>Squishing your first layer too much into the bed can lead to prints that are almost impossible to remove from the build plate when done.<\/li><\/ul>\n\n\n<p><strong>How to fix:<\/strong><br>Adjust nozzle to bed distance either by tightening the 3 or 4 levelling screws of your printer and using thicker paper stock for manual bed levelling or by adjusting your z-offset value when using a bed levelling sensor.

With the proper distance, extruded line is slightly squished, pancake-shaped.<\/li><li>Individual printed lines are barely sticking to the build plate.<\/li><li>Parts are warping off the build plate or become loose during the prints.<\/li><\/ul>\n\n\n<p><strong>Description:<\/strong><br>If your nozzle is too far from the bed there is not enough filament extruded to properly fill the space between nozzle and bed. The line currently extruding is barely making contact with the bed. Individual lines making up the first layer are not connected to their neighbors and they\u2019re not touching the outlines of your object&#8217;s wall.

If your adhesion is lacking, you might end up with warped print \u2013 or no print at all besides a huge mess of tangled filament on your bed (e.g. Green &#8216;birds nest&#8217; print you see here).<\/p>\n\n\n\n<p>Many common 3D printing problems stem from a <a href=\"https:\/\/www.3dsourced.com\/guides\/3d-print-first-layer-problems\/\" target=\"_blank\" data-type=\"post\" data-id=\"20131\" rel=\"noopener\" data-lasso-id=\"11355\">poor first layer<\/a>. The following are the various causes for bed adhesion to fail before or during a print.<\/p>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-144695\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Platform not level<\/h3><div id=\"ac-144695\" class=\"c-accordion__content\">\n\n<p><strong>Signs that your platform isn&#8217;t level:<\/strong><\/p>\n\n\n<p>Either your nozzle is too near or too far\u00a0(or both) at the same time along the X or Y-axis. Or in other words: if the left side of your nozzle is too close and the right side it is fine or even too high up, your bed is most likely at an angle \u2013 not level with the nozzle. The same goes for front and back and of course, this can happen on both axis at the same time.<\/p>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<p>When your platform isn\u2019t properly leveled, i.e. the nozzle to bed distance varies in different locations across the bed, your nozzle might be too close in some areas and too far away in others.<\/p>\n\n\n<p><strong>How to fix:<\/strong><br>On most printers, the print bed is leveled by adjusting 3 or 4 screws under the print bed. (If your printer is equipped with automatic bed leveling, this step might not be necessary even though it won\u2019t hurt to do it manually at least once initially). Leveling is actually not the correct term for what we\u2019re doing, but that\u2019s what everybody is calling it. What we\u2019re doing is to make sure that the gap between the nozzle tip and the bed is the same all across the bed. Hence: the bed and nozzle are \u201clevel\u201d with each other.<\/p>\n\n\n<p>In order to do so:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>Heat up your bed and nozzle to proper printing temperature, retract filament a bit and make sure the nozzle is clean (and no filament is oozing out during the leveling process).<\/li><\/ul>\n\n\n<ul class=\"wp-block-list\"><li>Move the heated nozzle to the first corner of the bed.<\/li><\/ul>\n\n\n<ul class=\"wp-block-list\"><li>Slide a piece of paper between the bed and the nozzle. Loosen or tighten the bed level for that corner screw until you notice a bit of drag when sliding the paper under it.<\/li><\/ul>\n\n\n<ul class=\"wp-block-list\"><li>Continue to the next corner, position your nozzle over it, adjust the screw so you get the same amount of drag.<\/li><\/ul>\n\n\n<p>Do so for at least all four corners, then check the middle of the bed.<\/p>\n\n\n<p>This might require multiple passes, as turning one screw usually affects the other screws as well. At the same time, while we\u2019re leveling the bed, we\u2019re also setting the nozzle to bed distance. By using thicker or thinner paper in this process you also set the nozzle to bed distance at the same time. The receipt paper from your last grocery store purchase for example sets the nozzle to bed distance usually works quite well for PLA while thicker paper might work better for PETG.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-144696\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Platform is warped<\/h3><div id=\"ac-144696\" class=\"c-accordion__content\">\n\n<p><strong>Signs your platform is warped:<\/strong><\/p>\n\n\n<p>While printing the first layer, a warped bed will show effects of the nozzle being too near or too far.<\/p>\n\n\n<p>One way to easily tell if your bed is warped would be to use a steel ruler or a straight edge, put it onto your bed and look at the gap between the edge and the bed. You might be surprised. Another way to find out: if you leveled the bed for all 4 corners, but the midpoint or some random points on the bed are off, then your bed is warped (or the axis bent).<\/p>\n\n\n<p><strong>Explanation:<br><\/strong>As with platform not level (above), a warped build plate will cause issues with the nozzle to bed distance. Uneven or warped build platforms is the most common mechanical problem we&#8217;ve seen in today&#8217;s 3D printers and it can be observed in all price classes and all bed surfaces. Neither a milled aluminum plate, FR-4 board, or even a glass sheet is guaranteed to be 100% even.<\/p>\n\n\n<p><strong>How to fix:<\/strong><br>Usually, you can work around warped build plates by printing a very thick first layer (but do not exceed maximum layer height = 75% nozzle size. i.e. 0.3mm for a 0.4mm nozzle). If all else fails, try printing with a raft. Also, with a warped build plate, leveling your bed in such a way that your nozzle to bed distance fits in a smaller area will allow you to work reliably with at least part of a warped build plate.<\/p>\n\n\n<p>Or in other words, when dealing with a warped bed do not try to level your bed at the 4 outermost corners, but pick a smaller area in the center of the build plate and try to level it as best as possible there. The idea behind this is that most of the prints seldom require the whole bed, so make a smaller area work well.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-144697\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Clean your bed<\/h3><div id=\"ac-144697\" class=\"c-accordion__content\">\n\n<p><strong>Signs the bed needs a clean:<\/strong><\/p>\n\n\n<ul class=\"wp-block-list\"><li>The bed isn\u2019t spotless clean, if you see debris from a previous print, dust, gunk, spots, etc.<\/li><li>You see lumps, build-up or an uneven coat of your favorite bed adhesive.<\/li><li>Look at the bottom of a finished print: do you see some dents in an otherwise smooth bottom surface that shouldn\u2019t be there? If so, chances are high something was or is still sticking to the bed there that caused the dent (or the nozzle was too close in that spot). When printing the first layer over a fingerprint on a glass plate for example, you can usually see the print bubble up in that spot<\/li><\/ul>\n\n\n<p><strong>Explanation:<\/strong><br>A dirty print surface will make your adhesion suffer. Any debris from previous prints needs to be removed before starting a new print. If your nozzle rumbles over leftover remnants of your previous prints it will start bouncing and it might introduce vibration in your printer depending on how stiff your bed carrier may be.<\/p>\n\n\n<p>Often overlooked is the detrimental effect of oily or greasy residue on your print surface, like for example a mere fingerprint.<\/p>\n\n\n<p><strong>How to fix:<\/strong><br>Degrease your bed surface regularly according to the manufacturer\u2019s instructions. Use either isopropyl alcohol\/isopropanol in a high concentration or pure acetone. Stay away from window cleaners, dish washing liquids and soaps, especially those that are supposed to be good for your skin, as most of them will leave a residue behind that will negatively affect bed adhesion.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-144698\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">First layer too fast<\/h3><div id=\"ac-144698\" class=\"c-accordion__content\">\n\n<p><strong>Signs the first layer is printing too fast:<\/strong><\/p>\n\n\n<p>The obvious sign that you are printing too fast is when the extruder can\u2019t keep up with pushing filament through at this speed and you see\u00a0<a href=\"#inconsistent-extrusion-under\">[Under Extrusion]<\/a>. This is true for the 1st layer as well, but you\u2019ll have to be way off for it to show. Determining the proper first layer speed is more \u201csubtle\u201d, the result is simply poor bed adhesion and there is no tell-tale sign that says: \u201cadhesion failed because it was printed too fast\u201d. Look at your slicer settings instead.<\/p>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<p>The speed you\u2019re printing your first layer at has direct influence over how well the molten filament bonds to the bed surface. Print slower to increase adhesion. Or faster to decrease adhesion. Since we\u2019re talking about prints not sticking to the bed, we want to increase adhesion, therefore print slower.<\/p>\n\n\n<p><strong>How to fix:<\/strong><\/p>\n\n\n<p>Every proper slicer out there has the option to specify a different print speed for your first layer. In Cura, it is called \u201cInitial Layer speed\u201d. In Simplify3D it is called \u201cFirst Layer Speed\u201d. We&#8217;re pretty sure your slicer has this setting as well, under some variation of those names. Usually, a speed of 30mm\/s or less is good for the first layer, you can increase the speed later on but experimenting is key.<\/p>\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h2 id=\"at-144699\" class=\"c-accordion__title js-accordion-controller\" role=\"button\"><strong>Check extrusion settings to ensure the proper amount of plastic is extruded<\/strong><\/h2><div id=\"ac-144699\" class=\"c-accordion__content\">\n\n<p><strong>Signs the wrong amount of plastic is extruding:<\/strong><\/p>\n\n\n<p>In general: signs that you\u2019re not extruding the proper amount of plastic are either under- or over-extrusion, infill leaving gaps, walls turn out too thin and layers not thick enough (not squished). However, for the first layer, there is usually no clear indication, as the result looks the same when your nozzle to bed distance is wrong. (So your best bet is to eliminate extrusion issues by doing a proper extruder calibration before leveling your bed &amp; setting the nozzle to bed distance).<\/p>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<p>Print distance (unless compensated by the printer) needs to match your first layer height and the amount of plastic that is actually extruded while printing your first layer. If your printer is not extruding enough plastic to fill the distance between nozzle and bed (3D printer under extrusion), you will end up with adhesion problems. Too much, or over-extrusion and you have excess filament that needs to go somewhere.<\/p>\n\n\n<p id=\"block-89c82684-6f14-4084-af97-3845d33893c6\"><strong>How to fix:<\/strong><\/p>\n\n\n<ul class=\"wp-block-list\" id=\"block-4efda7d4-b7e1-4f6c-9a1b-6f9d684a15ff\"><li>Calibrate the extruder steps required to extrude the requested amount of filament.<\/li><li>Check your extrusion multiplier in your slicer software to ensure proper amount of filament is extruded.<\/li><li>Check that you selected the proper filament size (1.75mm\/2.85mm\/3.00mm) in your slicer.<\/li><li>Ensure filament can be transported properly (i.e. filament unspools freely from the spool, no excess friction in the filament path).<\/li><li>Ensure nozzle isn\u2019t blocked or partially blocked.

Unless you\u2019re way off there is no telltale sign when dealing with adhesion issues that clearly says: your temperature was off. It either sticks or it doesn\u2019t stick &amp; warps. Later on in a print, problems like rough corners, curling or sloppy overhangs \u2013 or printing a temperature tower \u2013 will give better indications if your temperature might be off in general.<\/p>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<p>Many 3D printing first layer problems are caused from the incorrect printing temperature during the first layer as it directly affects adhesion to the build plate. Printing colder will decrease adhesion. Printing hotter (to a point) will increase adhesion. Stay within the manufacturer&#8217;s suggested range, at least around 10\u00b0C below the glass transition temperature.<\/p>\n\n\n<p><strong>How to fix:<\/strong><\/p>\n\n\n<p>Almost all slicers out there will allow you to set a different print temperature for your first\/initial layer.

But do not exceed the maximum recommended print temperature for the filament you\u2019re using to avoid the filament deteriorating in the HotEnd, which might lead to clogs.

Compare your slicer settings with the recommendations from the filament manufacturer. One indication that your bed temperature might be too high is the\u00a0<a href=\"#elephants-foot\">[Elephant foot]<\/a>\u00a0or curling close to the bed, where the defect gets less pronounced the further away from the bed you get.<\/p>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<p>Bed temperature (if your printer is equipped with a heated bed) has a lot of influence on how well your first layer will stick to the bed. A colder bed usually decreases adhesion, a hotter bed will increase adhesion. But do not set your bed temperature too high. A common problem we\u2019re seeing from our customers is setting the bed temperature way too high for the material they\u2019re printing with. You need to stay around 10\u00b0C below the glass transition temperature (Tg) of the filament you\u2019re trying to print.<\/p>\n\n\n<p><strong>How to fix:<\/strong><\/p>\n\n\n<p>Look up the glass transition temperature of the material you\u2019re printing. Ensure your bed temperature is at least around 10\u00b0C below the glass transition temperature. If your bed is far below the glass transition temperature and you\u2019re having trouble with your print not sticking, increase your bed temperature in 5\u00b0C increments until the issue is resolved (staying below the GT temp).<\/p>\n\n\n<p>For rigid.ink PLA for example, do not exceed 50\u00b0C. More is not better. If your bed is too hot, you will increase warping forces and the risk of prints warping or even detaching during the print is increased instead of prevented \u2013 and you\u2019ll invite other problems later on in the prints, like Elephant foot or caved in walls.<\/p>\n\n<\/div><\/div>\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h2 id=\"at-1446912\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Part cooling fan settings<\/h2><div id=\"ac-1446912\" class=\"c-accordion__content\">\n\n<p><strong>Signs you<\/strong> <strong>need to check your part cooling fan settings:<\/strong><\/p>\n\n\n<p>If your part cooling fan is spinning while printing the very first layer you need to look at your fan settings.<\/p>\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n<p>Enabled part cooling fans harden the printed line before proper bonding has occurred.

But do not exceed the maximum print temperature of the filament, as it might start to deteriorate in your nozzle and clog. Very common error is to boil rigid ink PLA by exceeding the maximum print temperature.<\/li><li>Check for warping. Warped areas are closer to the nozzle increasing back pressure.

That is in the case of an extruder motor when the force required to push the filament further is higher than the motors strength. Possible reasons include:<\/p>\n\n\n<p><strong>Deformed filament<\/strong><\/p>\n\n\n<p>Remove the filament from the extruder and check how it looks. Is it deformed, as in no longer round but crushed so that its diameter is now wider than it should be? If so you might want to try to decrease the idler pressure on your feeder gear.<\/p>\n\n\n<p>Conversely, if the filament is not crushed, but just has a gouge taken out of it where the hob gear has repeatedly slipped, increasing the idler pressure may restore correct filament feeding. Just don\u2019t overdo it or the problems listed above will likely happen.<\/p>\n\n\n<p><strong>Reduce strain<\/strong><\/p>\n\n\n<p>This problem is made worse when you\u2019re trying to print something that requires a lot of retractions in a short amount of time. Try to reduce the amount of retractions or set your retracts to be less aggressive.<\/p>\n\n\n<p><strong>Reduce friction<\/strong><\/p>\n\n\n<p>Check your filament path for excess friction.<\/p>\n\n\n<p><strong>Worn PTFE liner<\/strong><\/p>\n\n\n<p>A lot of HotEnds, even in direct extruders, include a PTFE liner, i.e. a short piece of Bowden tube somewhere between nozzle and heat break. In most Bowden style extruders, the tube extends all the way from the extruder down into the HotEnd. If this inner tube is worn or degraded (happens when printing too hot, usually above 260\u00b0C) the friction increases and might be too much for the extruder stepper motor to overcome.<\/p>\n\n\n<p><strong>Check PTFE liner gap<\/strong><\/p>\n\n\n<p>If the HotEnd uses a PTFE liner and it is frayed or has been cut at an angle. Any gap there will lead to clogs sooner or later as the melted filament will leak out around the outside of the liner causing the liner\u2019s inner diameter to deform and reduce.<\/p>\n\n\n<p>When using an Ultimaker: check the PTFE coupler in your HotEnd. It is considered consumable and will need replacement on a regular basis.<\/p>\n\n\n<p><strong>Nozzle clogged<\/strong><\/p>\n\n\n<p>Your nozzle or HotEnd is clogged. This could be any of the benign reasons like printing too cold, or too hot, or too fast, using too much retraction or nozzle to close to the bed, etc. But there are also some mechanical things to look into, especially if the problem reappears after you cleaned it.<\/p>\n\n\n<p><strong>To note:<\/strong><\/p>\n\n\n<p>If your HotEnd wasn\u2019t assembled properly, a common point of failure here is if the nozzle is tightened against the heater block instead of tightening it against the heat break.<\/p>\n\n\n<p><strong>Pro tip:<\/strong><\/p>\n\n\n<p>Increase the Vref of the extruder stepper, giving it a little more power to maybe push a bit stronger without skipping. But do keep an eye on the motor and driver temperatures if you do.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-1446932\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Bowden tube issues<\/h3><div id=\"ac-1446932\" class=\"c-accordion__content\">\n\n<p>If you\u2019re using a Bowden extruder, these are also common points of failure:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>There\u2019s debris in the Bowden tube.<\/li><li>The Bowden tube is worn in the inside and has increased friction.<\/li><li>The bend radius of the Bowden tube is too high.

Too much pressure and the drive gear of the feeder motor is likely to start grinding instead of pushing the filament.<\/p>\n\n\n<p><strong>Partial (or full) clog in the nozzle or HotEnd<\/strong><\/p>\n\n\n<p>See\u00a0<a href=\"#clogged-nozzle\">[Clogged Nozzle]<\/a>.<\/p>\n\n\n<p><strong>The nozzle being too close to the bed (bed levelling is off) or too close to the previously printed layer (warping)<\/strong><\/p>\n\n\n<p>See\u00a0<a href=\"#first-layer-issues\">[Nozzle to close to the bed]<\/a>\u00a0and\/or\u00a0<a href=\"#warping\">[Warping]<\/a>.<\/p>\n\n\n<p><strong>Trying to print too cold<\/strong><\/p>\n\n\n<p>Check the temperature range of the filament you\u2019re printing.

Stringing and Oozing<\/h2>\n\n\n\n<p>3D printer stringing and nozzle oozing are two common 3D printer problems that usually share the same root cause.

You may also be able to see the filament is very runny coming out of the nozzle.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-1446952\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Explanation:<\/h3><div id=\"ac-1446952\" class=\"c-accordion__content\">\n\n<p>As filament stringing and oozing is often caused by incorrect printing temperature and retraction settings.

Not having enough retraction can also mean more filament is being extruded and causes these issues.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-1446953\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">How to fix:<\/h3><div id=\"ac-1446953\" class=\"c-accordion__content\">\n\n<p><strong>Increase retraction distance<\/strong><\/p>\n\n\n<p>Increase the retraction distance in your slicer. There\u2019s usually a limit for how far up you can retract filament before you\u2019re running into other issues, but as a general rule of thumb: up to 3mm is ok for most direct extruders, 4-6mm should be ok for long Bowden systems.<\/p>\n\n\n<p><strong>Increase retraction speed<\/strong><\/p>\n\n\n<p>Increase the retraction speed. Maximum speed depends entirely on your extruder, so it is hard to come up with a valid recommendation, when in doubt try up to 40mm\/s. Check with your printer manufacturer.<\/p>\n\n\n<p><strong>Arrange prints closer<\/strong><\/p>\n\n\n<p>Long travel distances around the build plate tend to make your 3D print stringy, so if you can rearrange the objects to be closer on the bed, this could help against stringing 3D printing. This may not be an option for single item prints<\/p>\n\n\n<p><strong>Increase travel speed<\/strong><\/p>\n\n\n<p>Try increasing your travel speed in your slicer. Travel speed is the speed the speed the nozzle moved around the print bed. More speed means less time to ooze between layer points.<\/p>\n\n\n<p><strong>Calibrate steps and multiplier<\/strong><\/p>\n\n\n<p>Whenever you encounter any sort of extrusion issues, make sure your basics are covered &#8211; properly calibrated extruder steps\/mm and extrusion multiplier, both are key to nice prints. Over-extrusion encourages 3D print stringing. See\u00a0<a href=\"#inconsistent-extrusion-over\">[Over Extrusion]<\/a>.<\/p>\n\n\n<p><strong>Increase cooling<\/strong><\/p>\n\n\n<p>Increase cooling fans. Try increase in 20% increments, or try 100% when bridging or excessive stringing occurs.<\/p>\n\n\n<p>In some instances 100% fans may not be enough. Some users fit additional cooling fans or even just put a desktop fan next to your printer to increase airflow.<\/p>\n\n\n<p><strong>Print single objects<\/strong><\/p>\n\n\n<p>If printing multiple parts at once, try printing single objects instead of placing multiple objects on the build plate. This eliminates all travel moves between multiple objects and will cut down on 3D printing stringing &amp; oozing between multiple prints.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-1446954\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Filament specific tips:<\/h3><div id=\"ac-1446954\" class=\"c-accordion__content\">\n\n<ul class=\"wp-block-list\"><li>Flexible filament usually needs longer retractions as it stretches while being pulled backwards.

Lower your print speed gradually to test if this fixes the issue as you might be printing too fast.<\/p>\n\n\n<p><strong>Decrease skip<\/strong><\/p>\n\n\n<p>You may have set the infill to skip layers.

Standard retracts are happening while the extruder is stopped, which can lead to oozing and additional material being deposited on the model. The idea being using non\u2014stationary retracts is to retract while the nozzle is still moving, which might improve results.<\/p>\n\n\n<p><strong>Use a different restart distance<\/strong><\/p>\n\n\n<p>This is a setting in more advanced slicers. During retraction a configurable length of filament is pulled back from the nozzle before a travel move occurs. After the travel move completed, the same length is then pushed backed into the nozzle before actual printing restarts. Altering the restart distance allows you to influence what happens at the end of the travel move. You can tell your slicer to push back more or less filament than initially has been retracted.<\/p>\n\n\n<p>Use longer restart distance in order to make up for material that oozed during the travel move (usually used when you see dents or holes at the restart point). Or use a shorter (or negative) restart distance to push back less filament than initially retracted, which will help with eliminating blobs at the restart point<\/p>\n\n\n<p><strong>Printer cooler<\/strong><\/p>\n\n\n<p>Stringing at its heart is molten filament oozing out of the nozzle during a fast travel move. The hotter your print temperature, the more likely it is that oozing might occur. So when in doubt try printing cooler, reduce in 5\u00b0C increments performing small tests each time.<\/p>\n\n\n<p><strong>Try a different spool of filament<\/strong><\/p>\n\n\n<p>Some filaments are more prone to stringing than others. Not all brands print equally well. This is also true for different filament types. PETG is more likely to string than for example ABS. If you can\u2019t get rid of excessive stringing (after speaking to the manufacturer), try some other filament type or brand.<\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"blobs and 3D printing zits\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:150px\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"200\" height=\"150\" src=\"https:\/\/www.3dsourced.com\/wp-content\/uploads\/2022\/04\/DSC06170_a43dc1ac-628f-4e64-94a5-099ae58c0b80_x150.png\" alt=\"\" class=\"wp-image-14548\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"gb-headline gb-headline-4059169b gb-headline-text\" id=\"blobs-zits\">24.

There\u2019s two ways to go about this: either try increasing your retraction or disable the Z-hop.<\/p>\n\n\n<p><strong>Z-Scar<\/strong><\/p>\n\n\n<p>At the point where the layer change happens, a small blob will appear, the so-called Z-scar (or \u2018Zipper\u2019). It is not always possible to eliminate the Z-scar entirely by adjusting retraction settings, but modern slicers give you some choices where this Z-scar appears: the default is usually for the Z-scar to appear randomly or where the slicer thinks it would be best to optimise print speed.<\/p>\n\n\n<p>Usually you get a way cleaner looking print if you instead pick a specific less noticeable location for the Z-scar yourself. Like in a corner of a print, or at least somewhere in the back. Also choosing a specific location for the Z-scar will prevent the z-scar from splattering 3D printing blobs all over the print and confines them in more or less straight line along the Z-axis.<\/p>\n\n\n<p><strong>Dents<\/strong><\/p>\n\n\n<p>3D printer blobs and zits also appear on the surface of your print in random locations if your filament absorbed too much moisture. The steam building up inside the nozzle will make the filament pop at random times which will squirt out additional plastic (then followed by a dent because of lack of filament in the nozzle). Try drying your filament before printing to remove any moisture causing dent. To prevent moisture in the future, ensure you&#8217;re storing your filament correctly in an air-tight sealed bag with freshly charged desiccant, in a cool dry place. Do not leave filament out for longer than during printing.<\/p>\n\n\n<p><\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"Infill Poking Through Outline\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:150px\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"158\" height=\"150\" src=\"https:\/\/www.3dsourced.com\/wp-content\/uploads\/2022\/04\/Infill_Pokethrough_Angled_1_x150.jpg\" alt=\"\" class=\"wp-image-14550\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"gb-headline gb-headline-c1bc7aab gb-headline-text\" id=\"infill-poking\">25.

Depending on your infill percentage and your layer height, it may take a lot of layers to fully close the top surface over infill to produce a nice, smooth surface. Figure at least 1mm of combined layers for your top layer as a rule of thumb. So, if you\u2019re printing with a layer height of 0.2mm use at least 5 top layers to play it safe. Other ways to reduce 3D printing pillowing are:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>Print colder or increase fan speeds. Better cooling improves bridging performance, and that\u2019s basically what we\u2019re doing when printing over infill.<\/li><li>Use a higher infill percentage. More infill means smaller gaps, which are easier to cover.<\/li><li>Another possible cause for gaps in your top layer is under-extrusion . See\u00a0<a href=\"#inconsistent-extrusion-under\">[Under-extrusion]<\/a>.<\/li><\/ul>\n\n\n<p><strong>Holes and gaps in floor corners<\/strong><\/p>\n\n\n<p>These 3D printer errors happen where a horizontal surface meets an inclined one. The top layer(s) looks like the printer could not be bothered to print all the way to the edge. Its causes are similar in nature to pillowing, but it can be more annoying to nail the exact cause when everything else is looking great!<\/p>\n\n\n<p>There are a lot of possible causes of this, here\u2019s a list of problem and solutions:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>Under-extrusion can cause holes and gaps. Increase the extrusion multiplier\/feed rate, also see\u00a0<a href=\"#inconsistent-extrusion-under\">[Under-extrusion]<\/a>.<\/li><li>Not enough top layers &#8211; increase the top layers count so you are printing at least 1mm thick.<\/li><li>Printing too hot &#8211; print at a lower temperature so the plastic sets in position faster.<\/li><li>Printing too fast &#8211; slow down the print speed. This allows the extruded plastic to cool more before the next pass of the nozzle. If kept too warm, the layer will peel back from where it was printed.<\/li><li>Not enough cooling &#8211; if at all possible, increase cooling during the printing of these parts of the object. Always check this is suitable for the material you\u2019re using with the manufacturer.<\/li><li>Too little infill &#8211; increasing the infill percentage will help. Also look at the minimum infill length in your slicer and reduce this to allow smaller runs of infill to be printed at the edges of an object instead of being ignored.<\/li><li>The infill outline overlap is too small &#8211; all slicers can set how much the infill overlaps the outlines\/perimeters of the object being printed. This setting makes sure they go all the way to the edge and fuse together and so help support the layers above. Try increasing this and note the result (too much and you will likely see the infill pattern poking through the object\u2019s visible walls and other such surfaces).<\/li><li>Not enough outlines\/perimeters &#8211; these also have a support role to fill, so increase these if at all possible.<\/li><li>Too much retraction &#8211; causes there to be gaps in positions where retractions take place, so reduce this.<\/li><\/ul>\n\n\n<p><strong>Between infill and outlines<\/strong><\/p>\n\n\n<p>If this happens on your first layer, chances are your nozzle to bed distance is not set properly. Your nozzle is probably too far away from the bed. See chapter\u00a0<a href=\"#first-layer-issues\">[First Layer Issues]<\/a>. If it happens later in the print:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>This could be a result of printing too fast, try printing slower.<\/li><li>It could be a sign of (temporary) under extrusion. See\u00a0<a href=\"#inconsistent-extrusion-under\">[ Under-extrusion]<\/a>.<\/li><li>Another possibility is wrong extrusion settings in your slicer. Check what was dialled in is correct for your printer and print.<\/li><li>Increase your extrusion multiplier Simplify3D.<\/li><li>Increase extrusion width.<\/li><li>Increase overlap settings.<\/li><\/ul>\n\n\n<p><strong>Gaps between thin walls<\/strong><\/p>\n\n\n<p>When trying to print thin walls that are not multiples of your nozzle width in thickness, there is a common problem with slicers leaving a gap inside walls, severely weakening the structural strength of your wall. It is rather straightforward issue: if you\u2019re trying to print a wall that is 0.9mm thick with a 0.4mm nozzle, an average slicer might end up using 2 lines at 0.4mm each and leave a gap of 0.1mm, as it doesn\u2019t know a way to close the remaining 0.1mm.<\/p>\n\n\n<p>Therefore you should always strive to stick to a multiple of your nozzle width when designing thin walls to help alleviate the issue:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>Thin wall options &#8211; A lot of slicers today have special thin wall options, make yourself familiar with them and see where they can take you.<\/li><li>Adjust line width &#8211; Adjust (not necessarily increase) line width or the amount of outlines to force your slicer to construct your wall differently.<\/li><li>You can try increasing your extrusion multiplier to close the gap by intentionally over-extruding.<\/li><li>You can also set a narrower nozzle diameter in your slicer settings than you actually have fitted. If used with care and balanced against the extrusion multiplier, this can overcome some situations that your favourite slicer cannot cope with.<\/li><\/ul>\n\n\n<p><strong>Read more:<\/strong> <a href=\"https:\/\/www.3dsourced.com\/guides\/3d-print-gaps-and-holes\/\" target=\"_blank\" data-type=\"post\" data-id=\"20516\" rel=\"noopener\" data-lasso-id=\"11365\">every way to fix gaps and holes in 3D prints<\/a>.<\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\"><\/div>\n\n\n\n<div id=\"small parts &amp; features not printing\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:150px\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"200\" height=\"150\" src=\"https:\/\/www.3dsourced.com\/wp-content\/uploads\/2022\/04\/SeveredRotor1_x150.png\" alt=\"\" class=\"wp-image-14553\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"gb-headline gb-headline-eef49030 gb-headline-text\" id=\"small-parts-not-printing\">28.

Therefore, they intentionally leave a small gap between the support structure and the actual model that sits on top of it. The height of this gap is usually adjustable in your slicer settings. Less gap means better quality but also harder to remove.<\/p>\n\n\n<p>If the gap is too close, breaking off the supports will damage the surface of your actual object.<\/p>\n\n\n<p><strong>Dual extrusion<\/strong><\/p>\n\n\n<p>If you find yourself suffering from this problem a lot, you might want to think about getting a dual extrusion system. Printing with water soluble\u00a0<a href=\"https:\/\/rigid.ink\/products\/pva-soluble-support-material-1-75-mm-2-85-mm-0-03-mm-tolerance\" data-lasso-id=\"6318\" target=\"_blank\" rel=\"noopener\">rigid.ink PVA<\/a>\u00a0or the easy to remove\u00a0<a href=\"https:\/\/rigid.ink\/products\/break-away-1-75mm-3d-printer-support-filament\" data-lasso-id=\"6319\" target=\"_blank\" rel=\"noopener\">rigid.ink Break-Away<\/a>\u00a0will allow you to transition seamlessly from support to the actual model completely eliminating the gap and the problems it entails.<\/p>\n\n\n<p><strong>Increase support density<\/strong><\/p>\n\n\n<p>Support structures are usually not printed solid, but rather, like infill, use a percentage, often called support density. Increase this density to improve the surface quality of the part printed above the support.<\/p>\n\n\n<p><strong>Rotate Model<\/strong><\/p>\n\n\n<p>Often, the object to be printed can be rotated on the bed so less supports are needed. Or you could split the model in half using a plane cut tool and avoid the supports entirely.<\/p>\n\n\n<p><strong>Custom Supports<\/strong><\/p>\n\n\n<p>If you designed the model yourself, read up on design guidelines to reduce the need for supports in the first place, or how to place your own supports at design time.<\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"failing supports\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:150px\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"159\" height=\"150\" src=\"https:\/\/www.3dsourced.com\/wp-content\/uploads\/2022\/04\/SupportFail01BeforeEdit_x150.png\" alt=\"\" class=\"wp-image-14561\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"gb-headline gb-headline-ab6f3e54 gb-headline-text\" id=\"failing-supports\">36.

We\u2019re not sure why this is; some presume hotter temperatures will improve flow rate. Sure, there\u2019s a bit of a give here and there especially with thermistors not being the most accurate critters to begin with, but your first check should be &#8211; are you exceeding the print temperature recommendation for the filament used? We always suggest starting at the lowest point in the recommended range and work your way up in 5\u00b0C increments, if needed.<\/p>\n\n\n<p>Check with the filament manufacturer&#8217;s documentation to make sure. Just because it says \u201cPLA\u201d on the box, it does not mean they will all print the same! There are hundreds, possibly thousands, of different types of PLA produced across the world.<\/p>\n\n\n<p><strong>Print slower<\/strong><\/p>\n\n\n<p>Printing slower allows the heat building up in the printed object to dissipate before the next pass of the nozzle over the same area of the print.<\/p>\n\n\n<p><strong>Check\/increase fans<\/strong><\/p>\n\n\n<p>Make sure your fans are working. You can try to switch to fans that are pushing more air or add more fans. Sometimes, using a desk fan as a workaround can help you until a more streamlined solution is found.<\/p>\n\n\n<p><strong>Cooler ambient<\/strong><\/p>\n\n\n<p>The ambient temperature is too high. If your printer is enclosed, open all doors, side panels or top covers to keep the ambient temperature down. Even the best fans are inefficient if all they\u2019re doing is moving hot air around.<\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"burnt stuff dripping on your print\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:150px\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"160\" height=\"150\" src=\"https:\/\/www.3dsourced.com\/wp-content\/uploads\/2022\/04\/burntsml_x150.png\" alt=\"\" class=\"wp-image-14565\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"gb-headline gb-headline-cf0cf131 gb-headline-text\" id=\"burnt-dripping\">40.

While usually harmless, the print quality will suffer greatly from this.<\/p>\n\n\n<p><strong>What to do<\/strong><\/p>\n\n\n<p>If it\u2019s too late and moisture has affected the filament, try drying the filament or replace the spool.<\/p>\n\n\n<p>To prevent moisture store your filament dry, this is why we at rigid.ink provide special Mylar (metallic) resealable bags with each order. Maybe build a dry box for storage or even to keep the filament dry while printing sensitive materials like Nylons or PVA, with those materials, a few hours on an especially humid day is all it takes.<\/p>\n\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h3 id=\"at-14469147\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Smoke coming out of your nozzle<\/h3><div id=\"ac-14469147\" class=\"c-accordion__content\">\n\n<p><strong>Explanation<\/strong><\/p>\n\n\n<p>Usually this is a hardware issue.

I Cannot Print Model X<\/h2>\n\n\n\n<p>Places like Thingiverse, Youmagine, etc. are great for downloading free models to print. However, people uploading these models are not necessarily aware what design considerations need to be done for a certain printer type to be able to print the model in question. Sometimes all your 3D printing troubleshooting efforts can be mute if the file just isn\u2019t printable.<\/p>\n\n\n\n<p>Some models are designed for resin based printers and will fail miserably on FDM filament based printers. There are certain geometries that are impossible to print with filament based printers and throwing supports at it might not be enough to make it work. There are STL files that are not meant to be printed at all. Some models that should print ok are plain and simple broken. Some print fine unless you try to scale them.\u00a0<\/p>\n\n\n\n<p>Downloading STL files is a hit and miss kind of thing. Some work, others won\u2019t. You can try some of the free STL fixing tools, like Netfabb-online, MakePrintable.com or the like, but your results may vary. Not all STL files will print. Luckily MyMiniFactory boast guaranteed printable files, so this is usually a good place to start.<\/p>\n\n\n\n<p>Something that might help you sort out the good from the bad when browsing these \u2018free\u2019 model download sites.<\/p>\n\n\n\n<p>Taking Thingiverse as an example, if you see an object you are interested in printing, if there are no associated photographs of the printed object supplied by the uploader, and all you see is the system-generated blue object image &#8211; it might not be at all printable. Take a look at the associated comments section to confirm this one way or another.<\/p>\n\n\n\n<p>It may be that the model is just fine, or has only just been uploaded. In any case, if there is another similar object that has photos, comments and lots of downloads, you might be better off looking to see if that meets your needs first.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<p>I hope this troubleshooting 3D printing guide was helpful.
