Happy Valentine’s Day! In celebration, today we made a Möbius strip in the shape of a heart. The OpenSCAD code was kindly provided by kitwallace. From the side you can…
The Menger slices from Day 169 and Day 170 each divided the cube into two identical pieces. Today we make a a slice parallel to the Starmaker from the first…
Lots of people know what the inside of a sliced Menger cube looks like, at least the way we sliced it yesterday. But there are infinitely many ways to slice…
Today we made a white stand and slice illustrator to accompany the diagonally sliced Level 2 Menger sponge we printed on Day 155. Don’t look at the second picture until you…
Using the same OpenSCAD code of kitwallace’s from yesterday, today we made a Mobius-like solid whose cross-sections are triangles and whose boundary is the trefoil knot – that is, the knot…
Today we did not print an umbilic torus. But we did print a triangular-cross-section mobius strip, which is very close. In yesterday’s post we wished for a way to remesh…
Today I spoke with jamesford007, a student at SUNY Geneseo who is spearheading efforts there to bring 3D printing into the study of mathematics. He shared with me his technique…
We are going to be printing a lot of Menger-type objects, I think. Today’s is a level 3, sliced to reveal the stars. Model again by owens on Thingiverse. Here’s…
Thank you, owens at Thingiverse! You have made the impossible possible. It was great fun walking this print around the math department today, since everyone there knows just how difficult it…
The Holy Grail! Owens’ model Menger sponge with external support prints a beautiful Level 2 Menger sponge with no internal supports. The difficulty with printing a Menger sponge on a filament-deposition printer…
