Intro Video - 5 Week Immersion Program

Published May 16, 2018

The Open Source Microfactory Boot Camp - starting for the first time in 2018 - is part of a greater OSE immersion program for growing the OSE development effort. See this video - which covers both the 5 week Immersion Training and the 1 week OSE Boot Camp:

Summary

An immersion, 7 day course - August 25-31, 2018, at Open Source Ecology, Kansas City area, Missouri, USA

Learn to design, build, and use the open source desktop Microfactory in an immersive learning environment. The Microfactory consisting of important digital manufacturing tools: a 3D printer, CNC Circuit Mill, Laser Cutter, and Filament maker. Participants will build a 3D printer to take home with them, and learn how to set up an online print cluster as a small enterprise for printing parts. Atttendees will also assist in teaching a workshop on how to build the 3D Printer - to experience the teaching side of the equation.

All together, this is a crash course in open source product design and enterprise - using accessible, open source software, and the open source Microfactory for rapid prototyping. The basic microfactory involves a modular, Universal Axis motion system - allowing anyone to take our design and modify the design to any size and shape that they like. Because our design is based on common, off-the-shelf parts - participants can use the 3D printer to print parts for additional machines of the desktop Microfactory.

And - with the Filament Maker - one can turn scrap plastic to 3D printing filament - for closed loop manufacturing - while cleaning up the environment. Together with an online print cluster, we will show how average people can begin changing the landscape of production by using open source blueprints for common consumer goods. We will show how a professional grade cordless drill can be designed in an open source fashion, and how it can be built from scratch using the open source microfactory. We will start with scrap plastic that is turned to 3D printing filament - and used to print the cordless drill body. The body will be 3D scanned from an existing drill and reverse engineered. The CNC circuit mill will be used for the cordless drill charger, and the laser cutter will be used to make the battery charger enclosure. Together with easy-to-source parts, we will build the cordless drill from scratch as an example of a professional grade tool that can be built in the open source microfactory as a potential small enteprise.

Overview Schedule

  • 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. But that is only the beginning: we will introduce the Power Electronics Construction Set - and explain how simple, scalable power systems can be made with arduinos and transistors. This is relevant to building your own welders, plasma cutters, induction furnaces, wind turbines, electric vehicle controllers, and many other industrial and consumer applications.
  • 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.
  • Day 5 - The Open Source Everything Store. Imagine the open source version of Walmart or Amazon: all products are collaboratively designed and open sourced by people all over the world, and the products designed for fabrication in the open source microfactory. Can the next generation of democratic manufacturing bring production back to communities for responsible manufacturing? The key to this lies in developing effective crowd development techniques that leverage collaboration while avoiding the hardware version of Brook's Law. We will practice this on the design and build of a 3D printed cordless drill. We will study how large-scale design and prototyping events can take place in real-time, and how to leverage incentive prizes for such development. We will show an example of collaborative development by designing and building an open source cordless drill with speed control. 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 as a team. This is an experimental day designed to push the limits of collaborative design and prototyping using both onsite and virtual collaboration.
  • Day 6 - Enterprise. Now that we have learned good productivity skills based on open source equipment, we are ready to make economic impact. That is done by entrepreneurship that converts ideas into products of common use. We learn the overview of running an open source hardware and education enterprise. We will learn about open source enterprise software, and how to build a team for a continued and impactful effort of changing the technosphere to open source. Can we make open source product development the norm of how products enter our lives? The reward is a greater distribution of wealth and opportunity, environmentally sound supply chains, and a newly relevant producer culture - that can hope to transcend artificial scarcity.
  • Day 7 - Big Build Day. With the techniques and tools that we learned - we will apply our new skills to building a fully functioning, high performance 3D printer with a 1 cubic meter build volume. The nice thing is - we will do this from scratch and without a prior design. We will simply use the Construction Set approach and our proven design principles. We will use the part libraries, do the calculations, do the cutting, printing, and circuit milling - and build a decent product all by working as a team on the modular design. Our aim is to bring with us a library of common, admissible parts, and build the entire project from metal, transistors, raw circuit boards, and printed plastic - all in one day. We will push the limits of what can be done with the Level 1 Microfactory to build a finished product.

Dinner - Open Source Pool Party.

Day 7 - Build Workshop

  • Leaving - 8 AM - We will build a 3D Printer with a 3' large bed and metal frame - in 1 day. With all the learnings of the 6 days, it's time for a road trip to a nearby University to experience an extreme Design/Build Workshop in practice. We start - armed with FreeCAD design knowledge and design insights on the Universal Axis System - and design and build a large 3D printer. We will both participate as a team, and guide additional participants who sign up for the workshop. This will be an experimental workshop where we show the power of the Construction Set model in building larger, more powerful machines - while collaborating as a larger team. This is possible because we are using the modular Universal Axis system - where the interfaces between the different components are clear and well-proven, and specific design principles simplify the design significantly to create a product with industry standard performance - while reducing the part count to about 1/2-1/3. We will demonstrate the scalability of the print bed to any size - axis sizes - and show how the simple 8 mm Universal Axis system can be leveraged to make quality machines on a larger scale, at a fraction of the cost of similar designs. The event is designed to be an experiment in working as a team - as we push the limits in terms of the number of participants that can work constructively not only on a design/build - but also the documentation. Our goal is to develop techniques where meaningful collaboration can happen with as many people as can fit in any room. This means that a common understanding of open sourcce design and build techniques matches the availability of open source equipment to build the open designs.

Feedback

  • Zbynek - Is it happening? I am remote participant and there is nobody at the jitsi room I was told to join. I have been waiting a couple of hours by now. Can anyone help me?
    • in case anyone is wondering, the first day onsite internet failed so there was no streaming on Saturday
    • Sunday should have been at a different location with working internet connection - now we should be half way through the program but again no streaming so far
  • Bhakti - I would love to learn how to 3D print using different materials. Also, the CNC circuit mill is pretty cool. If you can add how to design the electrical circuit for newbies and translate them to the PCB, that would be great. ]
  • Dixon - As for the topics on the schedue, I am honestly most interested in the laser cutter topics, that said the schedule looks pretty good to me anyway.
  • Diderik - Learning about the OSE approach, the people and culture, more than is possible via reading the website(s), gathering input for initiating an Open Source Design R&D Hub in The Netherlands. One of the projects would be to "make a Makerspace" (or "Microfactory").
