Challenges
Frames can be manufactured by hand, with careful measurement and drilling. While meditative, this work is repetitive and laborious. Time studies of the hand production process using a drill press reveal that positioning the undrilled frame stock for precise drilling consumes the majority of effort. Automating the process in an affordable manner will reduce cost, increase availability, and free time for creative effort.
Approaches
Flat pack frame drill
The frame drill automatically drills regularly spaced holes in square raw material to produce reusable Replimat frames. It is constructed of a number of custom plates, motors, a controller, and several 3D printed parts.
