This Is The World’s Smallest Functional Circular Saw


By -

Once you have managed to 3D print world’s smallest power drill, the next task is to create another power tool obviously. That is exactly what Lance Abernethy did; 3D printed another miniature power tool for powering his Lilliputian toolbox. This creation is a 3D printed circular saw that can easily fit into a briefcase that is a tiny bit larger than a thumbnail.World’s Smallest Functional Circular Saw 4

Abernethy made use of Onshape software for the designing the saw and then printed it using Ultimaker 2 3D printer. It features all the components that a regular sized circular saw sports; a lade holder, two halves that constitute the main housing and a saw guard. The saw parts have a shell thickness measuring of 0.5mm while featuring a layer height of 21-40 microns. The whole assembly was printed in less than an hour.World’s Smallest Functional Circular Saw 2

Abernethy who is a maintenance engineer from Auckland, New Zealand said, “The saw was just a natural progression from the drill. I would like to be able to make a whole set of power tools just like my Makita set I have. I’m not sure how many I will get around to making though.”World’s Smallest Functional Circular Saw 3


It is being powered via small hearing aid battery and can be turned on using a very small button located on its handle. The saw doesn’t cut anything right now, however, Abernethy is working on a design that will eventually allow him to cut with this miniature saw. Good Luck Abernethy!
