How to export a STL design file using Autodesk 3DS Max

STL designs are good for all 3D materials.

1. Remove extra vertices

Select all the vertices and use the Weld function in the Edit mesh modifier to remove any double ups.

2. Check Triangulation.

3ds Max will triangulate your mesh when you export. Sometimes this can cause issues with smooth or curved parts of your model, so to check to see what it will look like, select all edges, and under Surface Properties press Auto Edge.

3. Unify normals

Select all faces and use Unify under Surface Properties to make sure the normals are facing the right way.

4. Check the model for errors

Use STL Check in the Modifier List to check your model for errors. For your file to export correctly, you must have no errors. Make sure you are not currently editing the model, or STL Check will return no errors, even if there are some:

Here’s a little support on how to fix errors that STL Check has picked up.

5. Export to STL

Choose File, Export (non-native). Select STL (*.stl) from the drop down menu and save your file:

6. Check the Export Settings

After you have clicked Save, make sure the STL Settings are set to “Binary” (the object name is not important) and click OK.

You’re now ready to...



Upload issues?

My file is too big

Your 3D design file must be less than 20mb. If it is not, you can make it smaller by reducing the number of vertices in your model. If you are using a MeshSmooth or Turbosmooth modifier, try reducing the number of Iterations.

I get a non-manifold mesh error, but I can’t find where it is

Use STL Check to find and select non-manifold mesh edges, faces and vertices. To make it easier to work on, try hiding large faces and checking your model from the inside out.

Too hard?
