Boy Surface ¶

3/30/16

Andrew Sommese asked me to print Boy Surface for him, as on display at Oberwolfach. Of course, I oblige!

I have prepared the model, and am waiting for another Klein bottle to finish printing. Tomorrow I will print Boy Surface.

Some prints for a topology class ¶

3/24/16

An instructor in the Mathematics department here at Notre Dame had heard that I print mathematical surfaces. So he came and talked to me about printing several objects for a topology class he is teaching. Today, I have completed printing those surfaces!

The surfaces include:

• a klein bottle (model not mine, but thingiverse thing)
• a torus
• a two-holed torus
• the real projective plane

Torus, two-torus, and real projective plane were computed by me, with help from Edward. The tori were computed directly from Bertini_real, while RP was explicitly parameterized.
