PrintPatch

PrintPatch is the 3D printing companion that actually learns from your prints.
Most troubleshooting guides give you generic advice. PrintPatch is different: it studies your own print history and tells you what's really going on — like "over-extrusion showed up on 6 of your last 8 prints with this spool, here's the fix." The more you log, the smarter it gets.

Built for FDM hobbyists and makers, and works fully offline.

SPOT PROBLEMS BEFORE THEY COST YOU FILAMENT
PrintPatch surfaces patterns across your prints — by spool, by material, and over time — and connects each one to a grounded, trustworthy fix from a curated knowledge base. No guesswork, no generic "try lowering your temperature."
