PCB heat bed
The Prusa designed PCB heat bed is a great addition to your Reprap printer to help your printing platform to be a heated surface perfect for minimizing warping of larger prints.The heating element is on the bottom side. The heating is done by long traces of copper.The top side is solid copper to keep the PCB flat enough.
If you want to make your printing platform flat enough, ideal stuff is glass sheet. Borosilicate glass is rated for higher temperatures than normal sheet glass making it a better material for use as a heated bed. After cracking a few sheets of normal glass from rapidly cooling or heating, borosilicate glass will quell your frustrations.
The Aluminium Bed Mount Plate design is pre-drilled and tapped to mount boltable bushings, the PCB heated print bed, belt standoffs, belt clamps. This mount plate is designed to fit onto a Reprap Prusa Mendel lm8uu 3D printer.
