3D Printer Construction Set
April 29, 2017 | Factor e Farm – Maysville, MO (USA)
Build Yourself. Build Your World.
The Open Source Ecology 3D Printer Construction Set Workshop is an immersion experience where you can build your own 3D printer, in one day. You have the option to take the 3D printer – called D3D – home with you.
The 3D Printer Construction Set is a set of building blocks that allows you to build a 3D printer of any size – and also – if the parts are enlarged but the same design principles are used – to build other machines including a CNC Torch Table, a CNC Router, and a CNC Laser Cutter.
Just another 3D printer?
While there are many different 3D printers out there – and they are becoming low cost and accessible – we felt that they are still complex enough to be beyond the reach of the average builder. To lower the barriers to 3D printing – and to multiaxis CNC machines in general – we decided to design the simplest possible 3D Printer – in the world. We have gotten the unique parts count down to about 40 – which is about half that of an average printer. Moreover, we are using magnetic connectors to attach the axes, tool head, end stops, power supply, the controller, and even the cable chain – making this system like a Lego set for rapid building of different machines. Our construction set approach allows us to stack, multiply, scale, piggyback, and otherwise reconfigure components for maximum flexibility. Our steel frame is heavy duty, so our system is more than a toy. We are designing a system intended to be scaled for industrial applications – consistent with our work on the Global Village Construction Set.
In this workshop, you will have an option to build 3 different 3D printer sizes:
- 16″ frame, 8″x8″ print bed, expandable up to 12″x12″
- 12″ frame, 8″x8″ print bed
- 8″ frame, 5″x5″ print bed
The 16″ frame version is the one shown in the video.
To create a Construction Set – we designed a small set of identical parts that can be reconfigured. The core part is the axis module – with the same axis module used in the x,y, and z directions – which is used to create the x-y-z motion system associated with an automated machine.
In this workshop, we are using 8 mm rods for the universal axis (about 5/16″) – but the rods/sizes can be enlarged – such as 1″ rods or even 2″ rods for heavier duty applications. The same axes as used above can be joined, lengthened, or stacked to build a much larger machine – such as this 4’x8’x1′ CNC Torch Table:
Note how the basic axis unit and its ability to connect to other axis units allows for a wide range of design variations, putting the ability to design CNC machines within the hands of ordinary people. Depending on the tool head that is used – the machine can have the functionality of the corresponding tool head – whether a 3D printer extruder, a router, a laser cutter, a cutting torch, or many others.
Parts can in principlebe stacked in multiples, as in this 9-headed production 3D Printer shown printing more parts for the axis unit:
The beauty lies in an absolute minimum number of parts that are used to build an infinite variety of CNC machines – depending on size, axis configuration, and tool heads.
This workshop builds upon OSE’s Extreme Manufacturing approach of rapid building with multiple teams working in parallel on modular components. By simplifying the design and streamlining the build with digitally-fabricated, open source parts – people are now able to build a high quality 3D printer in record time at low cost.
We are also developing an open source enterprise model for how to run such workshops anywhere in the world. We are publishing our enterprise model openly, with all supporting information that helps people in a successful startup – without reinventing the wheel.
This workshop is intended for those people who don’t have the time to build a printer themselves – or who don’t think they have the skills to build one – but who are interested in an extremely streamlined and efficient process. The intended audience is also anyone who would consider running Extreme Manufacturing 3D printer workshops as part of their livelihood.
Participants will gain an appreciation for the productivity that happens when we break down the design into clear modules, such that multiple components can be assembled rapidly or in parallel based on clearly defined boundaries. This is an application of OSE’s radical modularity, just like we are applying to the heavy machines of the Global Village Construction Set:
In this one day workshop – the participants will walk away with a basic understanding of how to design and build their own 3D printer – as well as other machine variations – using the OSE 3D Printer Construction Set, including software setup. Individuals who buy the materials package walk out with their own 3D printer. We estimate that the entire build should take 4-8 hours with one person – without requiring technical savvy from the participant.

If you are traveling – you may secure a hotel in Cameron, Missouri (15 miles away). Please note that there is no public transportation between Cameron and Factor e Farm and that we cannot pick you up or drop you off on a daily basis during the workshop. Car rentals are available at the KCI airport.
We have a shared-room dorm on site – HabLab. There is no extra cost for staying at the dorm and spots are filled on a “first come, first served” basis. Please note that this is a very rudimentary earth building and our accommodations are rough. The dorm rooms may be noisy due to late night conversations by participants. We do not have housekeeping, so you would be expected to clean up after yourself. Factor e Farm is an experimental facility that is permanently under construction, so please gauge your expectations accordingly. If you want a more comfortable stay, we recommend that you stay in a hotel.
We also have primitive camping on site which includes a composting toilet. Showers and a bathroom are located in the HabLab and there is a kitchen for basic food preparation.
The only transportation to our site is by car, as there is no public transportation in the area. The nearest airport is Kansas City International (MCI), about 1:15 hours away from Factor e Farm. FeF is located in a rural zone and there is no public transportation outside of long-distance buses stopping in Cameron. We do not offer airport transportation, though we may be able to coordinate a ride with other workshop participants and collaborators. Car rentals are available at the KCI airport.
For one day workshops, OSE does not provide catering. Participants may use our kitchen to cook and prepare food. Some snacks will be available. Participants are encouraged to coordinate with one another.
For multi-day workshops, we typically have dinner catered by local restaurants. However, since we’re in an isolated area, the number of restaurants available and the quality of the food may not be what you’re used to. There are only 3 restaurants in the area that do catering: a Mexican restaurant, a Chinese restaurant, and a Subway. Another option is for us to provide the ingredients and allow participants to self-organize dinner preparation (which means some of you would volunteer to cook for the group). Upon registration, we survey the group to find out what is the preferred option.
What to Pack
You are welcome to bring your own tools if you wish to – there is no such thing as too many tools. We will have all the necessary tools on site. For machine builds and house construction, we have gloves, protective eyewear, and hard hats. If possible, bring steel-toe boots – as that’s the safest footwear for any workshop. If not, please bring the sturdiest boots/shoes you have.
This being Missouri, the weather is highly unpredictable. It could be hot, it could be cold, it could rain – often all 3 on the same day. Bring clothes for all eventualities and weather. It can also get quite muddy when it rains, so sturdy boots are recommended.
If you plan to stay on site, please also bring a sleeping bag and a bath towel. If you’re staying in the HabLab, we have fitted sheets, pillows and pillow cases available – but you may want to bring your own pillow if that’s something that is important to you. If you’re camping, please pack everything you’d normally pack for a camping trip.
Early Bird Registration and Regular admission are available. See below for prices and Early Bird deadline.
2-for-1 Discount: bring a family member or friend with you for free (friend or family member assists you and does NOT take a second printer home).
