OG exemplary drawing
 
1. A driver-type golf club head comprising:
a metal body comprising a front wall, a sole, a front opening in the front wall and an external surface;
a metal face component affixed to the body to close the front opening;
a crown insert;
a component comprising a channel;
a lattice structure comprising a plurality of voids; and
a plurality of port holes extending into the external surface,
wherein at least of 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 of the metal body and fills only a portion of an internal cavity of the driver-type golf club head and is proximate the channel;
wherein the lattice structure comprises a uniform final material density of at least 90%,
wherein the lattice structure comprises a plurality of non-ordered beams,
wherein each of the plurality of non-ordered beams has a cross sectional shape selected from the group consisting of circular and elliptical,
wherein each of the plurality of non-ordered beams has a tapered diameter,
wherein the lattice structure comprises a region with a twisted characteristic, and
wherein the lattice structure is affixed to a portion of the sole and to a portion of the crown insert and curves generally away from the front wall.
