Golf club head

Golf club components with complex structures such as lattice structures, beam structures, and complex surface-based structures, are described herein. A binder jet machine is used create complex structures within these golf club components to optimize weighting, sound, and performance of golf club heads. These components may be manufactured using a method that 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.

Golf club head with binder jet printed lattice support structures

A golf club head with a sole having a low stiffness compliance zone, which allows the face to deflect downward upon impact with a golf ball, is disclosed herein. The compliance zone comprises a plurality of through openings that are filled with one or more filler pieces comprising a low modulus material, all of which are located within three inches of a face section measured along a front-to-back axis of the golf club head.

Golf club head with sole compliance zone

A golf club head with a central body component is disclosed herein. The central body component includes a crown portion and a sole portion. The crown portion is composed of a continuous carbon fiber reinforced epoxy material. The sole portion is composed of a chopped carbon fiber reinforced vinyl ester sheet molding compound material. The central body component has a front opening and a rear opening with a hollow interior.

A golf club head, preferably a putter head, comprising at least one structural support member is disclosed herein. The structural support member has a smooth, organic-looking aesthetic, with a continuously changing curvature along its spline and at least one surface, and preferably connects one portion of the golf club head to another portion. Where the support member connects to other portions of the golf club head, the surfaces of the member have a curvature that changes smoothly and continuously, lacking any sharp corners. The support member may be part of a lattice structure formed via binder jetting.
