Heatbed MK1 PCB
Printing on a cold surface just doesn't work. We've tried, and so have thousands of other RepRap builders. ABS simply does not stick well to cold glass/acrylic/tape. Prusa's MK1 Heatbed is the popular solution (yes, from the same guy who designed the "Prusa" Mendel).
The MK1 is easy to install: Solder two 12AWG wires to the MK1 and connect to your DC power supply. The board naturally pulls about 7-10A and heats to the stable temperature of 110C within minutes. You are responsible for obtaining and installing all wiring and mounting equipment as required by your specific RepRap.
