This disclosure describes three-dimensional printing kits, methods of making three-dimensional printed objects, and systems for three-dimensional printing. In one example, a three-dimensional printing kit can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer particles and a redox-active inorganic salt mixed with the polymer particles. The fusing agent can include water and an electromagnetic radiation absorber, wherein the electromagnetic radiation absorber absorbs electromagnetic radiation energy and converts the electromagnetic radiation energy to heat.

An improved golf club head is provided having a striking face portion, a topline, a heel portion adapted to receive a shaft, a toe portion, and a sole. The improved golf club head includes port holes extending from one or more cavities to allow insertion of a polymer and metal shot into the golf club head. The insertion of a polymer and metal shot facilitates increasing weight and/or biasing weight distribution of the golf club head. The improved golf club head may be manufactured by forging the main body of the golf club head, machining a recess into the main body, and attaching an insert in the recess. The recess forms a cavity and allows a port hole to facilitate insertion of the polymer and metal shot into the golf club head. After insertion, the polymer is cured to form the golf club head.
