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.

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

  • electric fence components (e.g. insulators)
  • lasso accessory: figure eight pattern or perforated plate called also kielasta in Finnish. The accessory is used to create a noose which is set to be tightened around reindeer antler Joshua (talk) 18:13, 22 October 2015 (PDT)
