By George Hart for the Museum of Mathematics
Color 3D printing allows one to make beautiful objects that are pretty much impossible to fabricate by any other technique. Here is a 9-inch diameter sculpture I designed and built on a 3D Systems Zprinter 450. The underlying geometry is based on one of the well-known stellations of the icosahedron, but I modified it, punctured it, and colored it to suit my taste.
If you are lucky enough to have access to a color 3D printer, you can make a copy for yourself using the data file available here. Below is a closeup shot of another example in this series, which emphasizes curves and gradations of color. You can see the rest of it and a series of related 3D printed color forms see here.

If you have already been watching MAKE’s alt.SXSW livestream, stay tuned today until 3:30 CST and you’ll catch MAKE’s official SXSW podcast. We are doing a SXSW Maker Show and Tell, profiling local Austinites and makers here for THE FESTIVAL. (If you have a SXSW badge, the panel is 3:30 at Driskill Hotel’s Maximillian Room, 6th and Brazos.)
Some of the fun we’ll be having:
- Joe DiPrima of ArcAttack! will be showing off some mad electricity tricks.
- Christopher A. Locke’s Heartless Machines (pictured)
- Dr. Bleep of Bleeplabs fame
- Ethan Reesor’s Jacob’s ladder
- Austin Tinkering School’s giant bow & arrow project
- 17 year old Markus Clardy’s “Android in Steel”
- YOU! If you’re here for SXSW and have a project you’d like to show off, come to the Driskill / Maximillian Room by 3 PM.
