3MFLint — 3MF slicer compliance and profile engine 3MFLint checks .3mf project files against a production standard you define: print profile, nozzle size, infill pattern, build plate, approved filaments, plate naming and filename convention. Mismatches come back with the corrected value, and most can be repaired and re-downloaded in one click. Your model never leaves your machine. The file is unpacked in your browser and only a small set of slicer settings is transmitted, never the mesh geometry or your custom G-code. Works with Bambu Studio and OrcaSlicer-family projects, including Snapmaker. JavaScript is required to use the app.
