Putter 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.

Additive manufacturing methods for golf club components

A golf club head comprising a body and a hollow stiffening structure is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The hollow stiffening structure extends within the hollow interior from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The hollow stiffening structure creates stiffness in a vertical, crown-sole direction of the body, while reducing stiffness in the horizontal, front-rear direction, and is filled with a weighted dampening insert that extends the entirety of the length of the stiffening structure and blocks entry into the stiffening structure.

Golf club head with stress-reducing features

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.

Support structures for golf club heads and methods of manufacturing improved support structures

Golf club components with complex 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 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.

Binder jet printed golf club components with lattice structure

Methods of creating golf products with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, and golf products that are created using those methods, are described herein. The structures described herein may be made from metal, non-metal materials, or combinations thereof, and may have one or more portions that are made from transparent or translucent materials.
