Winner of a the Gigabot social good contest

Open source 3-D printing of OSAT is gaining traction as groups like Re:3D (makers of the Gigabot) have sponsored contests to encourage designers to think about using 3D printers for social good, Michigan Tech sponsored the 3D printers for peace contest, the Plastic Bank, Techfortrade and the Ethical Filament Foundation are developing a new social economy for recycled 3D printer filament and Tekla Lab sponsored a contest to make open source lab equipment.

Do you have a great idea for a open-source appropriate technology that could be 3-D printed? First check out all the existing designs here. If you can not find it then click the "edit" below and post your idea. If you have an Appropedia account you can tag it with your signature --~~~~

In the Fall every year MTU will be offering a class in open-source 3-D printing. One of the assignments will be to design and prototype OSAT. 50 students use this page for ideas.

Designers if you see a request for an item you would like to work on - you can tag it with your signature --~~~~ as well and leave a message for the requester or collaborators.

  • Shapeways drone - rescue contest - fire fighters and other first responders use drones, like the DJI Phantom 4, to help in search and rescue operations? With its long range and integrated camera, the DJI Phantom 4 make it a valuable tool when searching for a small body in a large body of water. Now is your opportunity to help save more lives with 3D printing. Your mission is to design accessories to be added to the DJI Phantom 4 to help make it into the ultimate rescue drone.

  • Community feedback boxes that are easy to drop a note in but not possible for them to take the note out (as that should only be taken out by our designated staff) - that can be installed in communities for their feedback on projects

  • The FireAnt Prototype (contact: Wayne Johnson, email: , Friluftsliv Farm, Turtle Lake, North Dakota)

Small commercial robots designed to withstand outdoor environments currently cost over $10,000. This puts these devices out of reach for smallholder farmers with less than a hundred acres. Our goal is to drive these costs under $1,000 in successive iterations through open source designs and 3D printing. FireAnt will eventually be a 3D printable small-scale multipurpose robotic system to which one could add a variety of accessories for doing tasks around the farm. The first step is to create a rolling chassis and body to house the electronic hardware and power supplies and provide structure for the four wheels that will be driven by electric motors. It is essentially an inner box within an outer box. The outer box provides a way to attach the wheel/electric motor assembly, and store a Li-ion traction battery pack and a microcontroller that takes input from a GPS, gyroscope, and accelerometer and controls the wheel assembly motors. On top of the outer box would be a mounting plate and a mounting pattern that allows other devices such as cameras, LIDAR, robotic arms, etc. to be mounted with openings for the cables that connect these devices to its internal PC. The inner box would house a PC power supply and an internal PC (e.g. Mini-ITX PC) and other electronic equipment that the user may add. The dimensions of the outer box would be 13" W x 20" L x 10" H with a clearance of 2.5" from the ground. A wheel with tire is about 2" W x 8" H. The user should be able to easily remove the inner box to access the contents of the outer box. More details and examples will be provided on request.

Food processing[edit]

  • higher (electric) mill throughput, while maintaining efficiency
  • identify viable winnower
  • explore peanut milling
  • identify viable highly-efficient cooking appliances, e.g. induction stoves, electric pressure cookers, rice cookers, etc.
  • more efficient deep-frying

Bicycle parts[edit]

For MTU students interested in bicycle part design, Dr. John Gershenson has offered the use of his lab for measurements. existing bike hacks
