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 let’s 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
