Print Quality
Troubleshooting Guide



This guide is a great place to start if you are trying to improve the quality of your 3D printed parts. We have compiled an extensive list of the most common 3D printing issues along with the software settings that you can use to solve them. Best of all, the guide uses a large collection of real-world images to make each issue easy to identify when examining your own 3D printed parts. So letís get started!

Use the thumbnails below to identify the picture that most closely represents the quality issue that you are seeing in your own 3D printed parts. You can click on the thumbnail to jump that that portion of the guide for immediate recommendations on how to resolve the issue. If you are not able to locate your issues from the thumbnails, feel free to scroll down and read through each section of the guide in more detail. There are plenty of useful tips to learn that can help improve your 3D printed results!



Not Extruding At Start


Printer does not extrude plastic at the beginning of the print






Not Sticking To Bed


The first layer does not stick to the bed and the print quickly fails




Under-Extrusion


Printer does not extrude enough plastic, gaps between perimeters and infill




Over-Extrusion


Printer extrudes too much plastic, prints looks very messy




Gaps in Top Layers


Holes or gaps in the top layers of the print




Stringing or Oozing


Lots of strings and hairs left behind when moving between different sections of the print




Overheating


Small features become overheated and deformed




Layer Shifting


Layers are misaligned and shift relative to one another




Layer Separation and Splitting


Layers are separating and splitting apart while printing




Grinding Filament


Plastic is being ground away until the filament no longer moves, otherwise known as "stripped" filament




Clogged Extruder


Extruder is clogged or jammed and will no longer extrude plastic from the nozzle tip




Stops Extruding Mid Print


Printer stops extruding plastic randomly in the middle of a print



Weak Infill


Very thin, stringy infill that creates a weak interior and does not bond together well




Blobs and Zits


Small blobs on the surface of print, otherwise known as zits




Gaps Between Infill and Outline


Gaps between the outline of the part and the outer solid infill layers



Curling or Rough Corners


Corners of the print tend to curl and deform after they are printed




Scars on Top Surface


The nozzle drags across the top of the print and creates a scar on the surface



Gaps in Floor Corners


Gaps in the corners of the print, where the top layer does not join to the outline of the next layer



Lines on the Side of Print


Side walls are not smooth, lines are visible on the side of the print



Vibrations and Ringing


Vibrations that cause oscillations on the surface of the print, otherwise known as "ringing"



Gaps in Thin Walls


Gaps between thin walls of the print where the perimeters do not touch




Small Features Not Printed


Very small features are not printed or are missing from the software preview




Inconsistent Extrusion


Extrusion amount tends to vary and is not consistent enough to produce an accurate shape
