Simplify3D team had the good idea to realize this very comprehensive guide on a lot of problems. I invite you to consult it and add it to your favorites.

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!


Most of troubleshooting are fix with few steps :
