Nachi3D Laser Studio
LiveAI-assisted laser engraving design — generate and optimise artwork for LightBurn.
About this project
Overview
A desktop app that generates AI images optimized for laser engraving on wood and leather. The workflow I had before was janky — describe something to an AI image generator, get back a photo-realistic image full of gradients, then spend time in Photoshop making it engravable. This app builds the prompt engineering directly in, so what comes out is already high-contrast line art with no gradients, crosshatching for depth, and material-specific tuning.
The backend calls FLUX.1-schnell via HuggingFace's Inference API, then runs the result through a Sharp post-processing pipeline — grayscale, normalize, contrast boost, sharpen, threshold — to push the image toward something a laser cutter can actually use.
The whole thing ships as a Windows installer with Node.js bundled. Getting the CI/CD pipeline working on Windows runners was genuinely painful — NSIS has silent path-length failures that took several days to track down.

What I'd do differently
In hindsight
I'd skip the Express server entirely and run image generation directly inside the Electron main process — the client/server split added packaging complexity for no real benefit in a single-user desktop app.
