What to check before you export
A standalone STL does not retain 3MF colors, print profiles, materials, supports, or project metadata. Keep the original 3MF when those details matter.
For Cura, PrusaSlicer, and similar slicers, treat the result as a single geometry file: recheck plate orientation, scale, and material assignments in the destination project. If the package contains several objects, inspect the combined face count and bounds before printing.
Frequently Asked Questions
Does 3MF to STL keep colors and slicer settings?
No. STL stores surface triangles and does not preserve 3MF colors, materials, print profiles, or support settings.
Can I use the result in Cura or PrusaSlicer?
Yes. Download the Binary STL, import it into your slicer, and verify scale and orientation before slicing.
What if the 3MF contains several build items?
The parser applies supported component and build transforms. Review the preview and output bounds before printing.
