node-stl

Parse STL files with Node.js and get volume, weight, the bounding box, the center of mass and whether it is watertight or not.

example

const NodeStl = require("node-stl");

var stl = new NodeStl(__dirname + '/myCool.stl', {density: 1.04});
console.log(stl.volume + 'cm^3');     // 21cm^3
console.log(stl.weight + 'gm');       //  1gm
console.log(stl.boundingBox,'(mm)');  // [60,45,50] (mm)
console.log(stl.area,'(m)');          // 91.26 (m)
console.log(stl.centerOfMass,'(mm)'); // [30,22.5,25] (mm)
console.log(stl.isWatertight ? 'STL is watertight' : 'STL is not watertight');

node-stl recognizes by itself whether it is dealing with an ASCII STL or a binary STL file

load file from url

Use request to load a file from url

const NodeStl = require("node-stl");
const request = require('request');

const requestSettings = {
   method: 'GET',
   url: 'https://s3.amazonaws.com/minifactory-stl/WALLY_1plate.stl',
   encoding: null,
};

request(requestSettings, function(error, response, body) {
    var stl = new NodeStl(body);
    assert.equal(stl.volume, 21.87511539650792);
    done(null);
});

install
