3D printed circle saw actually works

Back in March, we talked a bit about a dude named Lance Abernethy from New Zealand who 3D printed a working drill. That little drill was very cool and Abernethy is back with a new 3D printed contraption, this time a circular saw. Like the drill, the saw was 3D printed using an Ultimaker 2 3D printer.

The individual parts of the saw were created using software called Onshape. The components are printed in PLA at a layer height of 21-40 microns with a shell thickness of 0.5mm. The entire printing process for the circle saw took an hour to complete. The tiny saw is made using four pieces.

The housing is made in two parts and the other two are the saw guard and the blade holder. The 3D printed saw gets power from a hearing aid battery and has a button on the handle that turns it on. The only downside to the 3D printed circular saw is that it can't cut through anything.

It's unclear exactly what sort of electronics are inside the tiny circle saw to make the blade spin. Abernethy says that he will be back with plans for parts that people can download and print to build their own tiny devices.
