In the Buildclass workshop series, participants were guided through the building of their own 3D printer over the course of two days, all the while building a fundamental skill set in digital fabrication. In 2015 and 2016 we built 3D Printers of with more than 150 people at institutions including John’s Hopkins University, University of Toronto, Baltimore Under Ground Science Space, and others. Over the course of these events we produced 60 units of our original 3D Printer design.
