They reminded me of the woodcuts by Wentzel Jamnitzer, a 16th century polyhedral artist. It's great that we can fabricate these things now. http://www.georgehart.com/virtual-polyhedra/jamnitzer.html I got to see some of these up close and personal at Capricon last year.

Could be wrong but I don't think laser cutting figures into this process. -Tonky You say: 3D-printed laser-cut metal

I think these would be 3D printed using a alloy dust – then fired in a kiln to vitrify.

Could be wrong but I don’t think laser cutting figures into this process.

She also makes available mathematical/geometric objects that are laser etched into the contents of crystal cubes and other shapes. One of the most wonderful is the rendering there of the 3D shadow of an 8 dimensional object -- the E8 Polytope.

I love them very much; and they're always an eye-catcher when folks come by the desk. Bathsheba Grossman's work is a delight to both have and hold; and one of the real delights is in inspecting these pieces from different angles in your hand, seeing the different facets and beautiful surprises waiting to be found. Disclaimer: I have no connection with the artist, his work, or shapeways. I just really like math art, and these have long been favorites.

The full-size sculptures are fabulous. A friend got us one of the little infolded spheres for a wedding gift, and we quite adore it. We saw her work at a show in Jamaica Plain a couple of years ago.
