Open Source Microfactory Specification

Introduction

The Open Source Microfactory is a 4000 square foot facility with critical equipment for modern manufacturing, from heavy metal fabrication to 3D printing, CNC, and metal rolling. It includes CNC grinders, circuit makers, robotic arms, screw machines, and air bearing lathes - and is capable of producing any technological artifact from a precision machined part to a car.

Equipment Base

1. 3D Printer - basic Fused Filament Fabrication machine for small parts at 100 micron vertical resolution. Capable of printing in PLA, and optimized for rubber printing. $500 material cost. D3D Pro.
2. High Temperature 3D Printer - $700 material cost. Printer fully capable of continuous production using PEI (high temperature parts), PEEK (piston and pump parts), Delrin low friction material for glide surfaces, polycarbonate for high strength parts and glazing, and ABS/PVC for architectural applications.
3. Large format 3D printer - for printing housing panels up to 4'x4'x8', and for printing airless tires and rubber tracks for tractors; $2000 material cost.
4. Production Printer - of 1printer with 4 heads for production part printing and printing in multiple materials
5. Ironworker machine - for cutting slabs, angle, and punching holes in steel in typical thicknesses of 1
6. Bandsaw - for cutting thick solid stock >1".
7. Waterjet Cutter - a precision cutter for all materials
8. CNC Torch Table - oxyfuel machine
