Corrupted 3D models for printing

Updated 2 months ago ​by Mikolas

You’d be surprised how many 3D models you can find on the internet are broken in some way. Modern slicers are pretty good at repairing the models without you even noticing. However, not all of the corrupted 3D models can be repaired automatically. Therefore, we would like to give you some tips how to repair these. 

Repairing corrupted 3D models

There are several ways to repair a 3D model. We’ll only focus on solutions that are free and easy to use:

  • Microsoft STL repair – online service
  • Meshmixer
    • Auto-repair – easy to use, but doesn’t always work
    • Make solid – that almost always works, but has its downsides
  • 3D Builder – really easy to use and a great tool, but only for Windows
