Hi Alan,

re:
> I understand that the OBJ file format may be even better than STL.

Well OBJ format supports a lot more things than STL like it can have materials in it but it is not likely that this additional information will be used by your slicer program.

Also OBJ format supports n-gons (polygons with more than 3 or 4 sides) but it's also not likely that the slicer is set up to handle those very well so you would probably want to use the option "Export: Triangles only" when you export the .obj file.

STL format is the one that is most frequently used for 3D printing data transfer.

If you want to export to a rendering program, that's when OBJ format is better to use than STL.

Yes, correct, it was another user that had some tutorials. I appreciate your response and dedication to your creation. That helps me make my decision.

Perfect. I always work with stl files and thought that if I was getting into multi material use such as colors, that OBJ contained some info such as that color information? Could be wrong. Have a Mk3S that will be getting the MMU2 treatment when it is fully vetted.

Hi Alan, yes that is true that you would want to use OBJ format if you do want to transfer color/material information. There is no way to have colors in STL files but there is in OBJ files.

You probably would want to set "Export: Triangles only" on the meshing options dialog when you do the OBJ export.
