Custom Heated Build Platform for Prusa Mendel 3D Printer

A lot of things going on at Pentaho have kept me away from this blog in the past months, but in the meanwhile, in my spare time, I've been playing with a couple of things. I had time to pimp up my 3D printer's heatbed for one thing.

The top layer is a piece of pyroceramic glass. It can withstand huge temperatures and supports very well abrupt temperature changes. This also means that it doesn't change shape at all when heated. This is the most critical requirement of a high end build platform for a 3D printer. If the base isn't perfectly flat (I mean down to 0.05mm precision)the prints will come out wrong.
