A heater for the build stage of a RepRap 3D printer which can be made by the standard home etch technique used for making PCBs
This heater has two parallel tracks and can be wired with them in parallel for use on a 12V supply, or wired in series for a 24V supply. The resistance of 1.6 Ohms per track allows quicker heating than the commonly available types..
Two types are provided, the first, HeaterA, was designed for my own printer and has holes for spring supports and locating pins while for HeaterB these have been removed so that it can be configured for mounting holes on the corners.
I don't know if the DXF file is useful - or even if it works. I added it as Thingiverse wouldn't accept that PDF files were legitimate production files
Instructions
The PCB laminate used was from Maplins as part no. FA59P, 305 x 203mm 1.6mm double sided FR4 copper weight unknown but believed to be 1oz. The laminate was sprayed with Maplins N17KH photoresist and developed with a universal PCB developer. The posative photographic transparancy was "Dataline" OHP transparancy film and was printed on a Brother MFC6510DW printer at "BEST" print setting. The back copper layer was protected with Kapton tape to prevent it from being etched.
