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…
Today we printed owens’ Diagonal Cut Menger Sponge design from Thingiverse. If you sliced a Level 2 Menger sponge in half along a diagonal plane as shown in the picture,…
To finish our collection of trefoil conformations, we have a stick knot and a cubic lattice knot: STL file for stick: http://www.geekhaus.com/makerhome/day153_trefoil_stick_40_25.stl STL file for lattice: http://www.geekhaus.com/makerhome/day153_trefoil_lattice_40_25.stl Thingiverse link: http://www.thingiverse.com/thing:234107 Technical…
Two more trefoil conformations – as a petal knot (all crossings line up along one center stem) and a tight knot (with the smallest amount of rope length possible given…
Continuing our collection of trefoil knots, today we printed a trefoil in a Fourier-(1,1,2) knot conformation and a trefoil knot in a tritangentless conformation. In other words, the first trefoil…
For the next four days we’ll be posting various mathematically interesting models of the trefoil knot. Mathematicians consider two knotted forms to be equivalent if one can be transformed into the other…
