Its finally here, heatbed is tested and ready to make your prints flat as pancake. It is a long story of testing and developing to make it really working and long lasting, you can check some background info in previous version here http://www.thingiverse.com/thing:2172 .
Active heated area is 20x20cm big and overall size is 214x214mm, its compatible with Mendel and all kinds of other RepStraps, just check if you can fit it on your bed. Its double-sided, so its more rigid and will not damage the heating element if you set wrong Z offset (thanks Joaz for this idea).
Its powered by 12V, prototype draws 9.9A when cold which goes down to 7.5A when hot. With isolation on the bottom of this heater, it reaches 100°C in about ~4,5 minutes, measured on the side of the heat field. These ratings may be slightly different on each PCB. It can be easily converted to use 24V or 48V.
I know guys from RepRapsSource and convinced them to fabricate these beds, so you can buy professionally fabri
