To find out what types of display configuration are supported check the configuration tool or file for your particular firmware. There will be pointers to some display types.
As for making pcbs on a 3D printer it is definitely possible. I believe this is the sanest, most reliable process:
- completely cover the pcb in permanent marker ink
- strap a very sharp nail/needle to the print head
- use the printer to scratch away the ink where you want the copper to be removed
- etch away using your acid of choice (usually ferric chloride)
