[Jonathan Ward] came up with the MTM Snap, a snap-together pcb mill as part of the Machines That Make group at MIT.
We covered [Jonathan]‘s previous work constructed out of half-inch plywood, however the new iteration of his PCB includes a clever snap-together system instead of screws as well as bolts. Although the MTM snap looks a great deal like3d printers such as a reprap, the similarities end with the off-the-shelf stepper motors. instead of utilizing motor drivers as well as manage electronics from a reprap, the job utilizes customized stepper drivers, managed by a bare Arduino.
We’re truly impressed with the results of the MTM snap compared with what is possible on a reprap-derived milling device like a makerbot or wolfstrap. We’re believing that’s because of the mass of this job compared to the printed ABS parts of the ‘common’ 3d printers, however any type of MEs are much more than pleased to appropriate that notion.
Check out the video after the break to see the device in action as well as a fantastic view of the snap-fit mechanism.
