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.

Reduce STEP File Size StarForge 3D Modeling Software

Lighten Tessellated CAD Parts

STEP, the ISO 10303 exchange format behind SolidWorks, Fusion 360, Onshape and FreeCAD, stores exact surfaces that turn into dense triangles once tessellated for a printer. Reduce STEP File Size reads the STEP model and decimates the resulting mesh to 300,000 triangles, keeping the look while dropping the dead weight, with nothing uploaded. The output is a 3D Print STL File ready for a slicer or an upload limit. StarForge 3D Modeling Software makes this mesh simplification for 3D printing free, with the effect of a Blender decimate modifier and none of the learning.
