Abstract: Summary A golf club face member is made by a manufacturing process, such as 3D printing, for a complex topology that is sturdy with good CT. 3D printing creates a face in which struts, a lattice-like structure, a waffle-iron pattern, or interior voids provide great strength and low mass. A golf club head has a club head body defining a heel portion and a toe portion and a hosel extending upward from the heel portion when the club head is at address. A face member is disposed between the heel portion and the toe portion such that it faces forward when the club head is at address. At least portion of the face member comprises a 3D printed material such as a 3D printed or sintered metal.
