Alex Feingold's Mathematical Art

I am a Professor of Mathematics with a strong interest in Mathematical Art. I have been making mathematical art by carving wood, carving stone, and casting bronze and iron, and welding. The results of my efforts over many years can be seen on my university website:  under the section ``Mathematical Art by Alex Feingold".  Now I am exploring how to make such art using 3D printing. My first goal was to recreate in jewelry size the Figure 8 knot with hypocycloid cross section (concave triangle) twisted 120 degrees as it goes around the path once, so that the resulting surface has just one side and one edge like a Mobius strip. This is my 1-Sided Mobius Figure 8 Knot. Compare it to the untwisted 3-Sided Figure 8 Knot which was much easier to design. I now have several other designs of mathematical art jewelry, as well as desktop size mathematical art. If you are interested in my wood, stone or cast sculptures, contact me by email.
