Slicer Engine3D model slicing, in Rust.

One engine, three surfaces — CLI, WebSocket server, and Angular UI via WebAssembly. Built on Clipper2.

Runs entirely in your browser

The web-slicer build compiles the full slicing pipeline — Arachne walls, infill, G-code — to WebAssembly. Drop in an STL, OBJ, or 3MF and get G-code back. No server, no install. Try it at slicer.maxscopp.de.

One engine, four surfaces

The same Rust core powers the CLI, the WebSocket server, the Angular UI via WebAssembly, and a native Tauri desktop app. No drift, no second source of truth — previews and final output agree by construction.

Clipper2 under the hood

Battle-tested polygon clipping for surfaces, infill boundaries, and wall offsets — wrapped in a clean Rust API and orchestrated by the slicing pipeline.

Scene engine SSOT

A unified scene module owns object placement, orientation, and transforms across every surface. CLI flags and UI gestures both translate to the same SceneOp.

Modern formats & dialects

STL, OBJ, and 3MF in. Marlin- and Klipper-flavored G-code out, with custom start/end blocks and lifecycle markers.

TOML configuration

Layered slicer.toml — defaults, then user, then project, then CLI flags. Deep-merged, per-object overrides, validated at the boundary.
