Print Settings Detector - Recommended FDM Settings From Your STL Mesh

Print Settings Detector turns a finished STL into concrete FDM starting settings. Upload the mesh, SliceFoundry measures overhangs, local wall thickness, tip-over risk, and overall size, then recommends layer height, nozzle, walls, infill, supports, and bed adhesion - with short reasons tied to those measurements. The same file always maps to the same recommendations.

Results are cached by a content hash of the STL, so re-checking a file you already analyzed is instant. No slicer profile guesswork disconnected from geometry - the guidance comes from the mesh you are about to print.

Who This Is For

• Makers with a downloaded STL who want a sane first slice without trial and error.
• Designers exporting from CAD or AI tools who need print-oriented defaults before sharing.
• Anyone unsure about supports - see whether steep overhangs actually dominate the surface.
• People printing small detailed parts or large shells - layer height and walls track feature size and thin-wall risk.

How It Works

1. Upload an STL (binary or ASCII, up to 20 MB).
2. Mesh analysis scores thickness, overhang area above the bed, stability, and extents.
3. Deterministic recommendations convert those metrics into FDM settings you can enter in any slicer.
4. Cached for next time - the same mesh hash returns the same analysis without re-scoring.
