How to convert 3DS to STL

  1. Add your .3DS file - drop it in the box above or click to browse.
  2. Convert it to .STL in a few seconds.
  3. Download your new .STL file.

What to expect

  • STL stores only triangulated surface geometry - materials, UV maps, textures, and any keyframe animation from the .3ds are lost on export.
  • Old .3ds files frequently have gaps between faces, duplicate vertices, or flipped normals; fix these in MeshLab or Blender's 3D Print Toolbox before sending the file to a slicer.
  • .3DS has no embedded unit definition, so check the model scale in your slicer after converting and rescale if the dimensions look wrong.

Frequently asked questions

Will textures and materials transfer to STL?
No - STL is a surface-only format that stores triangle faces and nothing else. If you need colour data in your print, export to OBJ or 3MF instead.
My converted model has holes - will it still print?
Non-manifold (open) meshes usually fail in slicers. Fix holes first using MeshLab's Filters > Cleaning and Repairing > Close Holes, or Blender's 3D Print Toolbox add-on.
I have a `.3ds` file from a Nintendo console - can I convert it to STL?
No - a Nintendo 3DS ROM shares the same extension but is a completely different file type; it cannot be converted to a 3D printable STL.
Is Blender free for commercial use?
Yes - Blender is open-source under the GPL licence and free for any purpose, including commercial projects.
