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.

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 catalog of products that compete with Amazon and Walmart - but are designed and 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 - and a bunch of readily available, off-the-shelf parts - we can produce a whole range of useful products, and thus begin to effect manufacturing in a substantial way. We are excited, and want to spread the word. So we run public workshops teaching people to build these machines, and how to design products that can be made with these machines - using a completely open source toolchain. We take this to our local libraries, schools, events - and involve thousands of people in collaborative product design. We teach people about massive parallel swarm-based development techniques - and every child and grandmother begin designing their own products and publishing the plans on the internet for free. The depth of local manufacturing increases - and people begin making more of the parts that would normally be purchased - such as motors and power supplies. We democratize the face of manufacturing - converting consumers to producers...

That is the narrative we'd like to see happen, and the 1 week OSE Boot Camp is an introduction to how to do this in practice. Some may say that this is already happening - but 3D printing and distributed manufacturing has not taken much of a hold in terms of replacing consumer goods. The key is high quality, proven designs - not fringe things on 3D printing websites that in many cases cannot even be printed. The key is engaging enough cooperation - that all the possible products truly become best-in-class - while remaining fully open source. We not only show you that this new mindset is possible - but how to build the actual production tools - and how to leverage massive collaborative development processes - so that we democratize product development on the face of this earth. Perhaps the greatest single impact is environmental - as people learn to build their products - they also know how to fix them - thereby putting an end to the throw-away society - with lifetime design that can be modified, improved, or recycled back into feed-stocks. Our aim in the OSE Boot Camp is to introduce people to the first steps in seizing democratic control of production.

Schedule

Detailed Narrative

• Day 1 - Intro + 3D Printer - We start with the open source design software, how to design a 3D printer using our Universal Axis system, and then build a 3D printer from scratch in the afternoon. We use common, off-the-shelf materials and 3D printed parts, so that the builds can be replicated easily anywhere in the world. This first day of the OSE Boot Camp is open to the public for one day participation with others who want to participate in the 3D printer build.
• Day 2 - 3D Print Cluster + Filament Maker - Did you ever think about producing useful products that can be part of a circular economy? Here we teach you how you can start your own microfactory at home - which you can connect to the internet as an on-demand printing service. To reduce the cost of 3D printing filament, we will teach you how to produce your own 3D printing filament from scrap plastic. Thus, the transition to distributed, closed loop production can start right at your home.
• Day 3 - CNC Circuit Mill + Open Source Electronics Toolchains -Besides 3D printed plastic parts, many consumer goods contain circuits. We will learn how to design circuits with open source software, and how to mill them using an open source CNC Circuit Mill. We will show how to import designs from KiCad into FreeCAD. As 2 examples, we will mill an open source switch mode power supply and inverter for producing useful power. The power supply can take 120AC into an adjustable DC value - such as power supplies for the 3D printer or CNC circuit mill itself - and the inverter can take a 12 v battery and turn it into 120 AC, for example for off-grid energy systems.
• Day 4 - Laser Cutting + 3D Scanning + Rapid Prototyping - We will learn about the full laser cutter toolchain - using OSE's open source laser cutter head add-on to the Universal Axis system. And then we go deeper: building a simple CO2 discharge tube for a CO2 laser: out of PVC pipe! Then we move on to rapid prototyping and reverse engineering: using pictures of a part taken from all angles, we will reconstruct a part as a detailed 3D CAD file in FreeCAD - using an open source photogrammetry toolchain. With working knowledge of 3D printing, laser cutting, and circuit milling - we will be in a position to design and build many consumer goods. We will show an example of collaborative development by designing and building an open source cordless drill with speed control, which we are also hosting as a design challenge on HeroX. For the cordless drill, we will 3D scan an existing drill as a starting point for our design. Together with the 3D printer, CNC circuit mill, laser cutter, and processing scrap plastic into 3D printing filament - and a capacitor-based battery spot welder - we will prototype the cordless drill.
