Golf club head
Methods of creating golf club components with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, are described herein. In particular, a binder jet machine is used create complex structures to optimize weighting, sound, and performance of golf club heads. The method preferably includes the steps of designing a golf club head component in CAD using optimization software, printing the component from a powdered material, and then removing excess powder from the component via port holes that extend into an external surface of the component and communicate with interior voids within the component.
1. A golf club head component comprising:
an external surface;
a lattice structure comprising a plurality of voids; and
a plurality of port holes extending into the external surface,
wherein at least one of the plurality of port holes communicates with at least one of the plurality of voids, and
wherein the lattice structure is at least partially bounded by the external surface;
wherein the lattice structure comprises a region with a characteristic selected from the group consisting of warped, twisted, distorted, curved, and stretched.
2. The golf club head component of claim 1 , wherein each of the plurality of port holes communicates with at least one of the plurality of voids.
3. The golf club head component of claim 1 , wherein the lattice structure is completely enclosed by the external surface.
4. The golf club head component of claim 1 , wherein the lattice structure comprises a plurality of non-ordered beams.
5. The golf club head component of claim 1 , wherein the lattice structure comprises a plurality of beams, and wherein each of the plurality of beams has a cross sectional shape selected from the group consisting of circular and elliptical.
6. The golf club head component of claim 5 , wherein each of the plurality of beams has a diameter that is selected from the group consisting of constant and tapered.
7. The golf club head component of claim 1 , wherein the lattice structure is composed of a non-metal material.
