Systems and methods for additive manufacturing of a golf club

A method of making a golf club head, the method comprising the steps of:

• providing a powdered material;
• depositing a binding agent onto a layer of the powdered material to form a green part, the green part including:
• a toe side, a heel side, a front side, a top side, a bottom side, and a rear side;
• a body that includes a toe region, a medial region, and a heel region, the body further including a topline extending from the toe region to the heel region, a sole extending from the toe region to the heel region and disposed opposite the topline, a front face having a striking face, and a rear face;
• and
• a segmented portion comprising a plurality of interconnected segments and a plurality of voids;
• removing excess powdered material from the green part;
• and
• sintering the green part to form a final part, wherein the final part includes the segmented portion that defines an external border of the body along the rear face, the external border being an externally-facing border of the segmented portion, and wherein the segmented portion defines an externally-accessible structure,
• wherein the segmented portion extends laterally and continuously over the medial region and at least a portion of each of the toe region and the heel region, and
• wherein the segmented portion defines a thickness such that the segmented portion extends into the body in a direction normal to a rear surface of the body,
• wherein the thickness is between 3 mm and 7 mm.
