Engineered-for-FDM supportless designs — overhangs tuned to ≤45°, bridging spans tested, and orientation pre-solved by the creator. Inspect overhang angles in the 3D viewer before your first print.
≤45° Overhang Guarantee
Creators orient and chamfer every overhang so standard FDM printers handle the file with zero support material.
Tested Bridging Spans
Bridge lengths are documented and print-tested by the designer — no guessing if your machine will close the gap.
Inspect Overhang Angles in 3D
Orbit the model in the viewer to check steep faces before slicing — no surprises when the print hits the plate.
HiddenMark on Every File
Supportless design downloads carry a unique watermark — creators can trace any shared or resold STL instantly.
0% Commission
Supportless designers keep 100% of every sale. A flat buyer fee funds Proofly — no creator commission taken.
