Abstract: 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.

Abstract: A putter-type golf club head having a body with a face insert composed of a cast urethane and glass microspheres is disclosed herein, as are methods of making face inserts with a polymer-microsphere mixture. The microspheres are non-uniformly distributed within the cast urethane to have a greater concentration of the microspheres at one section of the insert. The microspheres include K, S, iM, and XLD microspheres.
