Polar Bear is my massive Delta-style 3D Printer. This machine is an implementation of a BigDelta printer (link below).

This project has about 30hrs invested in it thus far. It's still early-on, and so I'm not going to post much on it for now.

This project is on ice due to a number of very uninteresting, non-technical factors. My DeltaFlyer project has taken most of my efforts that were going in to Polar Bear. Depending on the Flyer's success, I may resume the Polar Bear.
