3D Printed Bracelet
Today I printed the file bracelet.x3g on the MakerBot, which took roughly 50 minutes to complete. This is one of my favorite prints because it illustrates a very necessary design feature for thin objects such as this. Before the MakerBot can start printing the actual bracelet, it lays down a thin and flat scaffolding. This […]

A Cameo for our Silhouette Printer, Part II
This week I folded the three remaining polyhedra nets that I started last week. First up is the regular tetrahedron, more commonly known as a pyramid. The tetrahedron is made from 4 equilateral triangles. We also have a net made from 8 equilateral triangles. This net folds into a regular octahedron with four triangles […]

A Cameo for our Silhouette Printer!
The IGL is home to a Silhouette Cameo printer. This printer allows us to cut designs into card stock paper. While the possible uses of this machine are endless, our primary use of this printer is to cut polyhedra nets. Recall that a polyhedron is a solid living in three space made from flat faces, straight edges, and […]

Altgeld Hall
Altgeld Hall, beloved home of the mathematics department, was built in 1896-97 and was originally used as the university library. It later went on to become the College of Law, before finally becoming the house of the Department of Mathematics in 1955. For more historical information, click here. It takes a substantial amount of time […]

3D Printed Pendant!
Voronoi diagrams are irregular tilings of the plane. One places n points in the plane and forms polygons based on the following rule. Fixing a point in the plane, you compare its distance to each of the n designated points. The point will be in the interior of a polygon formed around the nearest point. […]

Tetrahedron: Wire Holder
A tetrahedron is composed of four triangles, three meeting at each vertex. This hollowed out tetrahedron was designed to hold and separate wires, perhaps in a computer lab. The tetrahedron was printed using file tetra_wire on the Ultimaker. The print took approximately 35 minutes.

Ultimaker Robot!
You probably aren’t surprised to learn that we print our Ultimaker Robot using the Ultimaker printer. The Ultimaker’s robot logo can be seen on the side of the machine. Our robot was printed from file ultimaker robot and took approxiamtely 40 minutes to complete. Penny for scale.

Cuboctahedron
A cuboctahedron is a polyhedron with eight triangular faces and six square face. For our cuboctahedron, we used the Ultimaker and printed the file of the same name, cuboctahedron. Since the print took slightly less than 10 minutes, I highly recommend this product for demonstrations. Becuase of its small size, it makes a great souvenir. Penny for scale.

A Stackable Cup
This cup was printed using the Ultimaker under file stackable-cup. I’ve deduced from the title that these are designed to be interlocking, i.e. stackable. Unfortunately I only have the one cup so far so I can’t report on the stacking properties. I’ll report back once we have a set. The printing time was about two […]

Octahedron
An octahedron is a polyhedron with eight faces. This week we printed one whose faces are all equilateral triangles, also known as a regular octahedron. We used the right extruder on the Makerbot and printed file octa2hollow. Since the print took slightly less than fifteen minutes, I highly recommend this product for demonstrations. Its a great […]
