We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

STL to 3MF Converter StarForge 3D Modeling Software

Open Print Files as Slicer Projects

Bambu Studio, PrusaSlicer and Cura all treat the 3D Manufacturing Format as their native project file, a zipped XML package that records real units and can hold several objects at once. The STL to 3MF Converter wraps a Stereolithography mesh into that container right in the browser, so a downloaded 3D Print STL File drops into a modern slicer as a tidy 3MF without anything being uploaded. It is free, needs no extra software, and is one of the many 3D printing format pairs handled inside StarForge 3D Modeling Software.
