An AI powered slicer designed specifically for the three.js ecosystem and inspired by the discussion on this issue. The idea is to be able to go straight from a three.js mesh to a machine usable G-code, thus eliminating the need for intermediary file formats and 3rd party slicing software.
Polyslice is designed to streamline the 3D printing workflow. Whether you're designing models in three.js or loading existing STL, OBJ, or other 3D files, Polyslice can process them and generate machine ready G-code. With built-in support for popular 3D file formats and the ability to send G-code directly to your 3D printer via Web Serial API or serialport, the entire design-to-print workflow can happen seamlessly in a web browser or Node.js environment. This makes 3D printing more accessible and eliminates the friction of using multiple tools.

npm install @jgphilpott/polyslice<!-- Include three.js first -->
<script src="https://unpkg.com/[email protected]/build/three.min.js"></script>
<!-- Include Polyslice next -->
<script src="https://unpkg.com/@jgphilpott/polyslice/dist/index.browser.min.js"></script>Here is a simple example to get you started:
// Require THREE, Polyslice, Printer and Filament (omit for browser)
const THREE = require("three");
const { Polyslice, Printer, Filament } = require("@jgphilpott/polyslice");
// Create the printer and filament objects
const printer = new Printer("Ender3");
const filament = new Filament("GenericPLA");
// Create the slicer instance with the printer, filament and other configs
const slicer = new Polyslice({
printer: printer,
filament: filament,
infillPattern: "triangles",
infillDensity: 30,
testStrip: true,
verbose: true
});
// Create a 1cm cube (10mm x 10mm x 10mm)
const geometry = new THREE.BoxGeometry(10, 10, 10);
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
// Slice the cube and generate the G-code
const gcode = slicer.slice(cube);To run this example locally follow these steps:
- Clone the Polyslice repo:
git clone [email protected]:jgphilpott/polyslice.git - Navigate into the repo directory:
cd polyslice - Install the node modules:
npm install - Compile the code:
npm run compile - Run the example script:
node examples/scripts/quick-start.js
