0 bytes uploaded. Print Orientation Optimizer runs entirely in your browser using three.js and WebGL. Your meshes never leave your device.
We minimise (a) overhang area below 45° and (b) horizontal footprint. The ideal orientation has lots of flat bed contact and few unsupported overhangs.
Yes — the JSON output includes a rotation matrix you can paste into your slicer, plus a downloaded STL with the rotation baked in.
The optimiser doesn't know which faces matter for fit/finish. Use the result as a starting point, then tweak based on your part's critical surfaces.
Rotate any STL/OBJ/GLB 180° around the X axis to fix upside-down imports. Common when bringing CAD into print slicers. Browser-based.
Open toolAuto-scale STL/OBJ/GLB models to fit any printer bed (X/Y/Z mm). Maintains proportions. Browser-based, no upload.
Open toolFind walls thinner than your minimum print threshold. Ray-cast across the mesh to detect thin sections that may fail to print or break. Browser-based.
