Export and print

STL, 3MF, OBJ — every printer, every slicer

What this actually means

  • 3MF carries real units, so you never hit the classic 「it arrived 1000× too small」.
  • STL is the universal fallback — even twenty-year-old software reads it.
  • Mesh resolution is adjustable: raise it for smooth curves, lower it for smaller files, with the triangle count shown before you export.
  • Select one part and you export just that part; select nothing and you get the whole model — no need to split the model first.

Common questions

STL or 3MF?
3MF whenever you can: units, colour, smaller files, better precision. Keep STL for old software and anything that insists on it.
How big are the files?
It depends on mesh resolution. A typical enclosure runs from a few hundred KB to a few MB. Curvy models grow noticeably at high resolution — that triangle count is there so you can judge before exporting.
Can I hand it to someone who will keep editing?
Yes. Besides the mesh formats you can export the whole project (parameters and source), and they can carry on from there — whereas an STL is baked, and all they can edit is the mesh.
