Abstract
A 3D printed metal coil for an electrical machine. The 3D printed coil has a plurality of turns and is configured to fit within a slot in an electrical machine. A cross-sectional shape of successive turns of the plurality of turns varies such that a portion of each turn forms a part of an external surface of the metal coil, the external surface forming an interface with a side of the slot.
