ThreeJS-export-STL

STL exporter for three.js

Can create both binary and ascii STL's.

Example

import * as THREE from 'three';
import { saveAs } from 'file-saver';
import * as exportSTL from 'Doodle3D/ThreeJS-export-STL';
 
const geometry = new THREE.BoxGeometry(1, 1, 1).clone();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00, wireframe: true });
const mesh = new THREE.Mesh(geometry, material);
 
mesh.position.y = 0.5;
 
const buffer = exportSTL.fromMesh(mesh);
const blob = new Blob([buffer], { type: exportSTL.mimeType });
 
saveAs(blob, 'cube.stl');

Installation

Using JSPM (ECMAScript / ES6 Module)

Install the library.

jspm install github:Doodle3D/ThreeJS-export-STL

Include the library.

import * as exportSTL from 'Doodle3D/ThreeJS-export-STL';

Using NPM (CommonJS module)

Install the library.

npm install threejs-export-stl --save

Include the library.

const exportSTL = require('threejs-export-stl');

API

exportSTL.fromMesh

data: String || Buffer = exportSTL.fromMesh( mesh: THREE.Mesh, [ binary: Boolean = true ] )

Creates a .STL from THREE.Mesh. When binary is set to true result will be a Buffer Object, when set to false result will be an ASCII string. The transformation on the THREE.Mesh will be applied to the STL geometry.

exportSTL.fromGeometry

data: String || Buffer = exportSTL.fromGeometry( geometry: THREE.Geometry || THREE.BufferGeometry, [ matrix: THREE.Matrix4, binary: Boolean = true ] )

Creates a .STL from THREE.Geometry. When binary is set to true result will be a Buffer Object, when set to false result will be an ASCII string. The transformation from the optional matrix argument will be applied to the STL geometry.

exportSTL.mimeType

mimeType: String = exportSTL.mimeType

A constant with the mime type of STL (application/vnd.ms-pki.stl).
