For Blender 2.70, I'm trying to figure out:

  • Which 3D printer file formats Blender natively supports
  • Which 3D printer file formats Blender can support with the use of plugins/extensions/etc.
  • Which 3D printer file formats can be converted into another format that works with Blender
  • Which 3D printer file formats Blender cannot support at all, ever

The most important one of those is the last one (which file types can Blender not import/export/modify at all). Can someone point me to any documentation or help me figure out which file formats fall into which group?


Blender supports the STL (STereoLithography) format which is supported by all printers and considered as standard for prototyping.

Shapeways for example supports the file types: STL, OBJ, X3D, Collada or VRML97/2.

Blender comes with support of STL, OBJ, X3D and Collada.

When there is a public demand for a specific file format someone will create an import / export addon for it.

  • $\begingroup$ Thanks @stacker (I'd upvote you if I had the rep to do so) - if STL is a standard for prototyping, what file format is considered "viable for production" (and, does Blender support that format)? Thanks again! $\endgroup$

  • $\begingroup$ @Venkat I'm not an expert on 3D printing. I just created a model and uploaded it to several sites which provide print services and all of them supported STL. This might be interesting: 3dprinting-forums.com/viewtopic.php?f=33&t=6844 $\endgroup$
