PCB heated print bed
thingiverse
PCB heated bed. I'm working on this idea for nearly two months, inspired by http://www.neufeld.newton.ks.us/electronics/?p=864 . UPDATE tested at 110W and its working flawlesly, gives 108°C in few mins Now I'm working on great mounting solution This is V4 22x20cm hated area you can select what resistance you want 1.3ohms (110W at 12V) or 21ohms you dont need any steel or aluminium on top, just plane kapton tape (I'm testing it at 21ohms setup with 55V PSU which gives me 144W and about 110-120°C, will test with 12V soon and I'll give a report) Instructions etch it on FR4 35um copper board, should cost about $20 or if you are interested email me I can probably etch some for you. Not tinning or copper plating, this would lower the resistance. There are 4 resistors on the board, final resistance depends how you connect them by solder bridges. Parallel -> 1.3ohms. Serial -> 21ohms.
