Take a Bambu Studio, PrusaSlicer or MakerWorld 3MF into a modelling tool — unpacked, merged and ready to edit.

From print project to editable mesh

A 3MF is a zip container: geometry, print settings, plate layout and thumbnails bundled together. Modelling tools do not want any of that except the geometry, and many still do not read 3MF at all. We unpack the container, apply each object's transform, merge duplicate vertices and write a plain OBJ.

Print settings and plate arrangement live only in the 3MF and are deliberately dropped — an OBJ has nowhere to put them, and you would not want them in a modelling tool anyway.

Frequently asked questions

Why OBJ rather than STL?
OBJ preserves UV coordinates and is the friendlier import for Blender, ZBrush, Maya and 3ds Max. If you are heading to a slicer instead, use 3MF to STL.
Can I get the separate objects rather than one merged mesh?
Not from this converter — objects are merged so transforms resolve correctly. Export each object to its own 3MF from your slicer if you need them apart.
Is this converter free?
Yes — up to 10 conversions a day and files up to 25 MB, no account needed. Larger files (up to 60 MB) and high-detail STEP output use credits ($9 for 20). Everything runs server-side on real geometry kernels, and failed jobs auto-refund.
What happens to my files?
Files are uploaded only to run your conversion and stored briefly so you can download the result. We don't share them, mine them or train on them. See our privacy policy.
