Day 199 – Triakis Icosahedron 640 480 mathgrrl

For the last week I’ve been printing whatever polyhedra appeal to me, and today I realized that everything I’ve printed is a Catalan solid. Today is the fifth, the Triakis Icosahedron¬†– dual of the Truncated Dodecahedron, and the first one so far that has triangular faces. This way leads madness; I’m going to have to print all of them now. Luckily, there are only thirteen Catalan solids. (Of course later I could print all of the Archimedean solids, then the Johnson solids, then Platonic solids and prisms and anti-prisms and arrgggh…)

  • We've had success printing the gyroelongated pentagonal bicupola from Day 192, by reducing the support density in Cura in a similar fashion to your knot profile. Butfrankly it works better for knots than for the polyhedra, and I'm really amazed that you can print such a complicated shape as this one and still get the support material out. How long did it take?!

    • Good question, I forgot to write down how long the printing took! Removing the supports isn't so bad but the ones with narrow triangles like this are the worst. I'll print up another triangle one and make note of the time and amount of support…
