Three Slicer

Slice 3D Models to Gcode in browsers. No install, no upload.

What it does

Prepare 3D prints without installing anything. Drop in an STL, get G-code — walls, supports, multi-material, even resin (.sl1). It's OrcaSlicer's engine ported to WebAssembly, so nothing is uploaded; your files never leave the tab. Free and open source.

Free online slicer for 3D printing. Convert STL, OBJ, 3MF and STEP models to G-code in your browser — an OrcaSlicer WebAssembly kernel, no install and no upload.

Three Slicer converts STL, OBJ, 3MF, AMF, PLY and STEP models into G-code directly in the browser, using a WebAssembly build of the OrcaSlicer kernel. There is nothing to install and nothing is uploaded to a server — the slicing runs on your own machine, in the tab. Open the slicer . No. The slicing kernel is compiled to WebAssembly and runs inside the browser tab, so the model file never leaves the machine it was opened on. There is no account and no server-side queue. STL, OBJ, 3MF, AMF and PLY are read directly, and STEP is read through a loader that is only fetched when a STEP file is actually opened; an .sl1 resin archive can be opened as well. The output is G-code for filament…from slicer.kimgh06.com

    3D print Z reinforcement via injected loopsJun 2026 · mgunlogson.github.io · ▲66

    Commodity FDM print strength is limited by poor Z-axis layer bonding. Parts crack along Z under stress. MAGMA tries to fix this in software that works on any FDM 3D printer. It's a fork of OrcaSlicer with a new infill type that creates paired U-shaped vertical channels inside the print, plus G-code that injects molten plastic into those channels to bridge Z layer interfaces with continuous plastic. Big caveat: I have a junky Ender 3 and haven't gotten a clean physical print yet. Don't expect this to work out of the box! After months of tinkering, I'm releasing the software so the 3DP…

    Hi HN, I’m the creator of SynapsCAD, an open-source desktop application I've been building that combines an OpenSCAD code editor, a real-time 3D viewport, and an AI assistant. You can write OpenSCAD code, compile it directly to a 3D mesh, and use an LLM (OpenAI, Claude, Gemini, ...) to modify the code through natural language. Demo video: https://www.youtube.com/watch?v=cN8a5UozS5Q A bit about the architecture: - It’s built entirely in Rust. - The UI and 3D viewport are powered by Bevy 0.15 and egui. - It uses a pure-Rust compilation pipeline (openscad-rs for parsing and csgrs…

    Share Slicer Settings for 3D Printers2015 · ▲11

    3D printers need slicer software to turn 3D models into print commands. Slicers have lots of configuration parameters, any of which could screw up a print. A couple months back I was looking for slicer settings to get my new k8200 printer working with anything other than PLA. A kind Redditor shared her settings on a private Github with me, but only after a couple weeks of forum hunting and Googling. That got me thinking - there has to be a better, faster way to do this.. I put together www.slicershare.com to make sharing slicer setting files dead easy. You can browse for slicer settings by…

    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-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.
