Nice page. I especially like the idea of printing semiconductors :-)
Maybe some consolidation or linking with http://reprap.org/wiki/Heated_Bed
I recently added there a spreadsheet for trace resistance calculation (hope
to not have errors on it) and a link to an online PCB trace resistance
About milling heated beds:
Also maybe some words of caution: people should not automatically assume
that the blank unidentified PCBs they buy in the wild (a.k.a eBay) feature
the "standard" copper layer thickness of 35 microns. From experience, can be
way less than that.
As a consequence, I had to patch my plate
(100x100 mm), but after that, it runs really fine.
No warping so far.
