How to Repair STL Files

blog-header-repair-stls

My first blog article for the new year for my friends at Pinshape is now available, and walks step-by-step through a number of common repairs you may need to make to your files prior to 3D printing – just click this link to read all about it and follow along. The main things covered are:

  1. How to repair holes and gaps in surfaces
  2. How to delete or trim unwanted surfaces, particularly useful for 3D scan data
  3. How to add thickness to surface geometry, turning it into a solid
  4. How to reduce file size

All of the tutorials use the freely available software Meshmixer from Autodesk, as it’s by far been the most user friendly tool I’ve found for working with .stl files, however you should have similar success using other free software like MeshLab or netfabb Basic. This tutorial builds upon another similar tutorial I wrote for Pinshape in 2015 called How to Modify an STL File: A Beginner’s Guide which shows you how to take a downloaded .stl (or one of your own) and begin customising it for your own needs, for example adding text onto the design.

I hope it helps improve your designs and your 3D printing success rate 🙂
