About

The UAB 3D PrintLab is located in the Department of Computer and Information Sciences. Our charter is to do research in Computer Graphics, Solid Modeling, and Fast Prototyping. We have a number of 3D printers ranging from hobby-level machines to industrial strength models. As of late 2013, we can print in both ABS (sturdy, suitable for test-and-fit) and PLA (non-toxic, bio-degradable, suitable for implant).

The lab is also equipped with computers and special purpose devices devoted to capturing data which is later converted to solid models suitable for printing. We do 2D and 3D imaging, and laser range finding. We are especially interested in research on converting these various sources of input data into usable solid models.

3D printing services are available to anyone at UAB. We are actively seeking collaboration with researchers in all fields who have interesting problems that can benefit from this technology. We also provide routine 3D printing services, at prices designed to cover basic costs.

theGömböc

The Gömböc

Gömböc is the name for any convex 3-D body that is of uniform density and has only one stable equilibrium and one unstable equilibrium. They are also known as mono-monostatic bodies. Gömböcs where first conjectured by Vladimir Arnold in 1995 and proven to exist by Gábor Domokos and Péter Várkonyi in 2006. The body on …

TheMixUAB: 3D printing — from bones to buildings

Kenneth Sloan, Ph.D., a specialist in computer graphics and director of UAB’s 3D Print Lab, talks about the technology that recent articles predict might be used to create everything from replacement heart valves to moon bases. Sloan helped us separate the possible from the hype. The podcast is available at UAB’s research blog themixuab.blogspot.com, www.facebook.com/TheMixUAB, …

Like Clockwork

These parts were generated by a student in the Intro to Graphics class. There’s one part missing from this pile – can you tell which part has escaped? [never fear - it was printed separately, the clock will work…as soon as he figures out how to put all the pieces together]

Positive and Negative Treads

If the shoe fits… Ground truth was a foam block with the impression of a shoe tread. We scanned the foam block and designed a plastic brick with the impression on one side…and a positive print of the shoe that made the impression on the flip side.
