Desktop CNC Electroforming Machine

Classical machining operations largely fall into the "subtractive manufacturing" category - operations that remove material from a solid billet to form the desired part. In recent decades, however, new forms of "additive manufacturing" have become available. In these cases, a CNC machine is used to add material to the workpiece to build up the desired features on the part.
