3D printing seems to have some sort of turning point in the last few months. Lots of people know what it is and many are experimenting with it. This week I began teaching on my History of Mathematics module; yesterday’s lecture was about Archimedes. I would never imagined that the two could be combined but today I saw a preprint on the arXive on the combination of Archimedes and 3D printing. The paper has a brief history of Archimedes and his works (and quite a few elementary typos) and focusses on how to make models of his inventions, for example his water screw, and more mathematical objects using a 3D printer. I don’t have access to 3D printing but would be intrigued to give some of the Archimedes models a go. Certainly, it would be great to have a supply of Platonic and Archimedian solids to show students. Has anyone out there tried something...
