3D printers are the tool of choice for all the hackerspaces we’ve been to, and laser cutters take a close second. There’s another class of plastic manipulating machines that doesn’t get enough credit with the hackerspace crowd – the vacuum thermoformer. Surprisingly, there haven’t been many – if any – vacuum formers on Kickstarter. Until now, that is.
[Ben] and [Calvin] are the guys behind the MOFO, and built their machine around ease of use and reliability. After a few prototypes, they settled on their design of aluminum extrusion for the frame, a ceramic heating element for the heater, and an off-the-shelf PID controller for the electronics.
The MOFO has so far been tested with polycarbonate, acrylic, PETG and styrene with good results. The Kickstarter has reward levels of $500 for a 12″x12″ work area, and $1000 for a 24″x24″ work area. That’s not too bad, and building your own similar thermoformer would probably cost just as much. Just the thing if you need to print out a few dozen sets of storm trooper armor.
