Today’s post is contributed by Scott Sherman, otherwise known as loki3 on Shapeways, where he has a wide variety of exotic dice models, including a new kind of d4 and even…
Today we look at two objects that I had trouble printing on a Replicator 2 without doing some fixes. Usually when a model won’t slice with MakerWare, I use MeshLab…
Today we printed a large copy of a Rhombic Tricontahedron (Day 203) to give to a doctor friend who is leading the pack of those trying to figure out a…
We liked yesterday’s little Buckyball so much that today we printed pmoews’ Large Buckyball from Thingiverse. Both models are icosahedral; you can see the icosahedron shape if you look at…
Today’s print is the small Buckyball model from pmoews’ Buckyball Easter Egg gift set on Thingiverse. Like owens’ Menger Sponge with External Support model (see Day 157), this Buckyball prints with…
Last week I used the shell model from Day 237 in class and it was so great to get to that point at the board where my picture is all…
More shells! This time we printed a model to match an example from the Khan Academy, so that you can go there and learn how to set up the definite integral…
Tomorrow in calculus we’ll be discussing how to approximate volumes of solids of revolution using “shells”. This is traditionally a very difficult concept for students to visualize, so having a…
Today, eight models we’ve seen before, optimized for printing small and fast. We’ll be printing one of these tiny models for each person that comes to the Fall Meeting of…
This semester five students and I have been 3D-printing the knots through 7 crossings in both standard and special configurations, as part of our MATH 297 – Knot Theory Research and…
