	*'''Day 8-9''' - We get industrial! We will work with the [[2" Universal Axis]] to build a heavy duty CNC machine with a goal of 200lb of tool force at 10 micron resolution. We will build on our past work with the Universal Axis to produce a much stronger version with 36x the motion force than the 3D printer - by using 50 mm steel rods instead of 8 mm rods as the basis of the motion system. We will also build a 3D printer that prints in solid metal - by using the 1" universal axis and a 1 meter print bed - where we simply hang a MIG welder gun on the tool head instead of using a plastic filament extruder. This gets us to printing fully solid, functiuonal steel objects. We will start by 3D printing heavy duty drive sprockets for the [[MicroTrac]] tractor.		*'''Day 8-9''' - We get industrial!

	*'''Day 5''' - geardowns. Planetary, split ring planetary, and stacked geardowns to connect our new motor to drive a Precious Plastic Shredder. Planetary geardown for a Nema 17 motor. Large geardowns. We will experiment with how to make efficient geardowns for attaining high torque using 3D printed parts, and will measure the practical limits that can be achieved. Split ring planetary geardown with a Nema 17 Motor for 100x higher torque. People have used planetary geardowns for 600 lb winches - so there is room for exploration.		*'''Day 5''' - geardowns.

	*'''Day 6-7'''- We will explore open source product development by collaborating on an a 3D printed, cordless drill. We allocate multiple 3D printers for real-time, on-demand prototyping without long wait periods for parts. We will design and build various geardowns, battery packs, and simple 3D printed circuits (component holder structures for soldered components), and put together a functional cordless drill. Here we let the creativity of the group take over - for applying CAD design rapid prototyping. We will provide crash course tutorials on cordless drill design, electric motor design, battery pack design, and controls, building of 3D printed planetary gears, and other topics relevant to making a cordless drill. We will aim for building a 3D printed cordless drill motor, but will have off-the-shelf electric motors to experiment with as well.		*'''Day 6-7'''- We will explore open source product development by collaborating on an a 3D printed, cordless drill.

	The focus is around gaining decent understanding of the tools and techniques necessary to build small mechatronic devices - such as 3D printers or cordless drills as the cases in point - with fully open source tool chains. This includes developing open source motors, electronics, heating elements, drive systems, and geardowns that can be applied to building many other types of products. We focus around the 3D printer as a universal prototyping tool, and teach [[Open Source Product Development]] techniques that we have been developing at OSE to leverage open collaboration for open source product design.

	We are preparing to deploy an Incentive Design Challenge in 2020 - a global collaborative development challenge aimed at producing a professional grade cordless drill. We are planning on leveraging a significant reward ($250k) to engage wide participation - but the rules are different. We will reward collaboration - where building upon other contributors' work is required to solve a challenge greater than any single person could do. We are focusing not only on the design of the cordless drill - but also the design of an enterprise infrastructure such that these open source drills can begin filling the shelves of local hardware stores. If this works out, we will have demonstrated the true power of open collaborative development for ~~economically significant results~~ - using fully open source toolchains.

	In 2019 we are offering an experimental, public-interest design, STEM boot camp Summer Camp that combines both well-prepared builds and time for experimenting with design and prototyping. The first 3 days cover building 3D printers and learning to design objects using open source FreeCAD software. The remaining part of the Summer Camp involves experimentation with a wide variety of CNC machines, 3D printed electric motors, 3D printed geardowns, and electronic controller for the 3D printed motor. We focus around OSE's [[Universal Axis System]] - a scalable and modular plantform for building CNC machines based on a common set of parts. Participants have a chance to build a 3D printer on the first day to take home with them - and to use this printer in prototyping throughout the week. We will build 2 more CNC machines in the week: a metal 3D printer and a heavy duty CNC mill for manufacturing engine parts. We will also do a prototype build of a 3D printed cordless drill including 3D printed battery pack and motor - as a test of the collaborative development methods. The goal of the week is to equip participants with a wide array of skills that allow replication of OSE's modular build techniques.

			==General Schedule (to be finalized)==
	On day 1 - we build the OSE D3D 3D printer - a 3D printer that is intended for unleashing industrial productivity on a small scale. We will build our latest version - [[D3D v19.04]]. We feature silent operation, the Titan Aero extruder with Volcano nozzle for printing deposition rates up to 5 lb per day, and a PEI, insulated heat bed that heats faster and uses less energy than any other comparable 3D printer.(*show data on heat time and graphs of bed energy use). We are using our scalable [[Universal Axis]] motion system, which means that you will learn how to build larger machines using the same basic building blocks. The design is fully open source and intended for widespread replication.

	*'''Day 2 - Learn to use your 3D Printer and to design objects using open source CAD'''. This will be the foundation for doing useful design in the remaining days of the Boot Camp. We will teach you how to use FreeCAD to do simple and complex design so you can create and modify 3D printing files using a completely open source toolchain. We will teach you a basic, but powerful workflow that can be learned in 1 hour of hands-on practice - so that you can add effective CAD design to your skill set as one of the core outcomes of the Boot Camp. To test the accuracy of your printer, we will 3D print calipers that have up to 50 micron accuracy. We will teach you how to switch to different nozzles for printing - depending on if you want high detail or fast prints. We will teach you how to design printable objects, and how to prepare them for successful printing.		*'''Day 2 - Learn to use your 3D Printer and to design objects using open source CAD'''.

	*'''Day 3 - Large 3D Printer'''. Today we will build 2 large printers - one that has a 1 meter bed, and another that is a 6' tall 3D printer. To do this, we will use the 1" size [[Universal Axis]] in the larger printer. We will print with large printing nozzles of 80W - which can print up to 20lb of plastic per day. This means that 3D printing of large objects such as furniture or building materials such as plastic lumber now becomes feasible.		*'''Day 3 - Large 3D Printer'''.

We will build on our past work with the Universal Axis to produce a much stronger version with 36x the motion force than the 3D printer - by using 50 mm steel rods instead of 8 mm rods as the basis of the motion system. We will also build a metal 3D printer using the 1" universal axis at 1 meter print bed - where we simply hang a MIG welder gun on the tool head instead of using a plastic filament extruder.

	*<strike>'''Day 5 ''' - It's time to turn our 3D prints to metal. We will experiment with lost plastic casting using [[PolyCast]]. We will encapsulate 3D prints using plaster of paris and greensand - and make metal objects from Zinc Aluminum alloys. We will brew our own zinc aluminum alloy from zinc, aluminum, and a little bit of copper using a small furnace.
	*Circuits for controlling motors
	*'''Day 3 - Build a Filaments Maker''' - OSE is about industrial productivity on a small scale - meaning that we want to print useful, lerger-scale objects in addition to small 3D prints. For OSE, that means printing plastic lumber, rubber tires for vehicles, glazing panels for greenhouses, chairs and furniture, and much more. For that - 3D printing fiament costs become prohibitive, as commercial 3D printing filament costs are $10/lb - which makes printing of any sizeable objects cost-prohibitive. This is where the open source filament maker comes in, where we can produce 3D printing filament from waste plastic. We will build 1-4 filament makers (depending on how many people register for the course) from easy to source, off-the-shelf parts - and start making our own filament on Day 3. Thus, if we use scrap plastic - our filament cost drops 100x from $10lb, to about $0.10 per lb. 3D printing costs another 10 cents/lb in electricity. But don't take our word for it - we will take data using an improved and insulated version of our 3D printer - with super fast printing nozzles - to reduce printing costs to well bolow the above figures. We will break up into 2 groups, with one group working on the Filament Maker, and another on the plastic shredder - using the newly built 3D printers to produce parts on demand as a swarming print cluster.

	~~==Other Possibilities==~~
	~~<strike>~~
	*Build a filament maker for producing 3D printing filament from scrap plastic'''. We will teach you how to design a practical filament maker so that you can take every-day plastics from the waste stream and turn them into useful 3D printing filament. After a design session - you will learn how to actually build a working filament maker. We will build a filament maker similar to the Precious Plastic design - but redesigned for a simpler build that can be done easily as a group in One Day. As such, we will break into 2 groups and build 2 filament makers. After going through this process, you will know a filament maker inside out. We are also offering kits for the filament maker so you can Build Yourself, after this workshop.
	*Making filament and composing filament formulas - We will use the newly-built filament maker to produce 3D printing plastic from scrap PLA, ABS, PET, and PVC - and mix these with each other as well as sand, sawdust, and other materials to produce composite filaments. The process starts with grinding, for which we need to use grinders.
	*Playing with ~~Geardowns and Building a Plastic Shredder - Give me a lever long enough... and I shall move the world. - Archimedes. We will 3D print planetary gears and apply them to building a~~ heavy duty ~~shredder.~~
	*Building ~~an open source,~~ 3D ~~Printed Cordless Drill''' - we will 3D print electric motors, use the CNC Circuit Mill to mill circuits and aluminum, and experiment with Desktop Metal Casting to make~~ metal parts from low melting Zinc Aluminum alloys that melt in a pot right on your stovetop at only 420C. We will also make simple circuits using 3D printed circuit making techniques. Combined with the planetary geardown and a battery pack based on common 18650 cells - we will spend 2 days designing and building a functional cordless drill starting from waste plastic, aluminum, and post-1982 pennies.

	On day 4 and 5 - we will build 3D printed brushless electric motors and 3D printed planetary geardowns. We will also build the control electronics for the motors using simple circuit production techniques that combine 3D printing with laser printer based circuit fabrication. Our goal is to demonstrate that we can get practical power levels from the 3D printed motors - and that we can apply these homebrew motors to drive high torque devices such as the [[OSE Shredder]] by using high-torque, planetary geardowns.

	~~Day~~ 8-9		On days 8-9 - we go to heavier industrial applications. We are also dedicating 2 days for exploration of a heavy duty CNC mill using the larger [[2" Universal Axis]]. If more than 12 people register for the workshop (our ideal number is 24) - then we will split to a second group which builds a metal 3D printer using the 1" universal axis. This is nothing more than mounting a 200 amp MIG welder torch head as a toolhead instead of the plastic filament extruder - so we print in solid steel. This requires a design where the motion components are hidden from the weld spatter - which is easy to do using our modular Universal Axis system.
	We are also dedicating 2 ~~extra~~ days for exploration of a heavy duty CNC mill using the larger Universal Axis
