The regular ABS print was painted with conductive copper paint and then had a thin layer of copper deposited over it using electroforming. The process is similar to electroplating, but the metal coating is much thicker.
The ultimate goal is to electroform a thick enough layer that the ABS print could be dissolved out leaving just the metal. This is my first attempt at electroforming (the first one worth showing off anyway).
