Open Source Microfactory Boot Camp

Narrative

3D printing and open source micromanufacturing, in its infancy, has great potential for distributing production. We start with a 3D printer, learn how to build one, and set up an online printing service for producing parts. In order to expand our enterprise - and enable the printing of large objects at low cost - we diversify into producing 3D printing filament from scrap plastic. We grind down scrap plastic, extrude it into 3D printing filament with our filament maker, and then wind it onto spools with the filament winder. Produced at a cost of only 10 cents per lb - we have inexpensive 3D printing filament that is almost free. So we can run an online 3D printing service successfully. But can we then develop high value products that are competitive with standard consumer goods? That is our goal. So we collaborate on the Open Source Everything Store, where we design a whole catalogue of products that compete with Amazon and Walmart - but are produced locally. Household consumer goods total a $20T global market - so the pie is large and there is plenty of room for collaboration. It turns out that with 3D printing, a CNC Circuit Mill, and a small laser cutter/engraver - we can produce a whole range of useful products, and thus begin to effect manufacturing. We are excited, and want to spread the word.
