First reported by 3Ders.org, the saw was designed piece by piece in a computer modeling program, then brought to life using an Ultimaker 2 3-D printer. Powered by a hearing aid battery, the sawblade spins when you press a button, though for now it can’t actually cut anything except air. That should change in the next version, though. There’s even a little case to put it in.
What Lance came up with, was a four part design, featuring two sides of the main housing, as well as a blade guard and a blade holder. All were 3D printed on his Ultimaker 2 3D printer in PLA material. ‘It’s printed with a 0.25mm jet nozzle using the Olsson block upgrade from 3dsolex.com and 0.04mm layer height,’ he explains to 3ders.org. With a shell thickness of 0.5 mm, total printing time was less than an hour.
