Electroforming

(Taken from Wikipedia)
Electroforming is a highly specialized process of metal part fabrication using electrodeposition in a plating bath over a base form or mandrel which is subsequently removed. Technically, it is a process of synthesizing a metal object by controlling the electrodeposition of metal passing through an electrolytic solution onto a metal or metallized form. More simply, a metal skin is built up on a metal surface, or any surface that has been rendered electroconductive through the application of a paint that contains metal particles. Essentially, a metal part is fabricated from the plating itself.

This differs from electroplating basically because the skin is much thicker and can exist as a self-supporting structure if the original matrix, or mandrel, is removed. The object being electroformed can be a permanent part of the end product or can be temporary (as in the case of wax), and removed later, leaving only the metal form, the “electroform”.
