There was a contest to develop 3D printable files for the International Space Station's 3D printer. The winner got a 3D printer ... runners up got Fluke DVOM's and all entrants got a t-shirt.

ISS 3D Print Contest

They offer 3 materials: ABS, HDPE, and PEI+PC ... I'm not familiar with the last one. Anyone know?

If found this material on Matweb: PEI+PC Alloy

These links are thought to last a very long time. I hope many of you decide to upload a project into contest site and compete for the grand prize ... A sweet John Fluke DVOM. If nothing else a free awesome T-shirt.

PEI - polyethermide is a "common" coating for heated print beds. PC is so many different things, but in this context, it's likely to mean polycarbonate plastic. From what I've read, it's challenging to print with and especially challenging to get a good bond on the build plate. One reference suggests to use a PEI coated bed with a slurry of ABS applied prior to printing. As with so many things 3d printer related, many people have many different methods. The above one appears to be well received as a successful method.
