Printproof

What it does

PrintProof converts multi color 3MF files from OrcaSlicer and Bambu Studio into GLB, OBJ, and USDZ with paint colors intact. Built by reverse engineering the undocumented paint format. Free, open source, fully client side, with AR preview and a Node CLI.

See your multi-color 3D print before you print it. Printproof parses Bambu Studio, OrcaSlicer, and Snapmaker U1 3MF files without losing color data, lets you recolor zones live, preview true-size in AR, and export GLB / USDZ / a re-sliceable 3MF. 100% client-side, no uploads.

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  I trained a 125M model to autocomplete piano on-device▲598

  I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
