Key point

Web Three Slicer slices 3D models directly in the browser without requiring a server or installation.

Details

Web Three Slicer is an open-source project that runs a slicer engine and viewer for 3D printing in the browser. It was implemented as a WASM kernel and npm package by reverse-engineering OrcaSlicer, operating without a separate server or installation.

It accepts the following 3D model files as input and outputs G-code.

  • STL, OBJ, 3MF, AMF, PLY
  • STEP support via a plugin loader

Reloading a .3mf project created in the slicer restores the build plate layout and settings. The repository is organized into a packages directory containing the engine and a web directory containing the web application.
