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!

Thumbnail Overview

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 of Print

Printer does not extrude plastic at the beginning of the print

Not Sticking to the 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
