Maker 3D prints the world’s tiniest working circular saw


Lance Abernethy has 3D printed a fully-functional saw that’s no larger than your thumbnail.


Last year, Lance Abernethy 3D printed a mini, fully-functional cordless drill. But why stop there? The New Zealand-based Maker has now added another tiny tool to his collection: a fingernail-sized circular saw.

Abernethy designed each of the saw’s four components — two body pieces, a saw guard and a blade holder — using Onshape CAD software and printed them out on his ATmega2560 driven Ultimaker 2 machine. The itty bitty parts were made of PLA at a layer height of 21-40 microns and shell thickness of 0.5mm. The printing process itself took just under an hour to complete.

Not unlike its brethren, the circular saw is powered by a small hearing aid battery and starts working at the press of a button its handle.

While the wee saw may not be powerful enough to cut through anything (other than tearing a piece of paper, maybe), the Maker does hope to make another iteration that has a bit more oomph to rip through small pieces of wood, in addition to creating other equipment that would fit inside his miniature toolbox (or what he calls “little brief cases”).
