A golf club including a golf club head formed of metal by an additive manufacturing process, the golf club head including a front side, a rear side, a bottom side, a top side, a toe side, and a heel side, a body that defines a toe region, a heel region, and a medial region, a first plane that extends orthogonal to a ground plane, a second plane that extends orthogonal to the ground plane, a front face, a topline, a sole, a plurality of laterally-extending grooves, a toe portion, a heel portion, a hosel, and a cavity that is enclosed by the front face and the body. The ground plane is a horizontal plane parallel to the ground when the golf club head is at address. The front face and the body are formed of sintered metal. The hosel defines a hosel cavity that is configured to receive a shaft.

Systems and methods for additive manufacturing of a golf club

Golf club head

A golf club head that includes a body that has a topline, a sole, and a front face. The front face defines a rear surface that extends along a plane and the body defines a center of gravity plane. The golf club head also includes a lattice structure formed on a portion of the body, layer by layer, via an additive manufacturing process. The portion of the body is bounded by the plane, the center of gravity plane, and an intersection between the plane and the center of gravity plane.

Golf club

A process of manufacturing a golf club head. The process comprises the step of spreading a thin layer of metal powder over a build plane defined over a build platform. The process also comprises the step of selectively depositing droplets of a binding agent over the thin layer of metal powder in order to bond the metal powder. The process further comprises the step of sintering a green part body to form the golf club head. The golf club head comprises a lattice structure positioned within an internal cavity of the golf club head. The build plane is offset from a ground plane by between about 5 degrees and about 160 degrees. The ground plane defined as a horizontal plane parallel to the ground when the golf club head is at address. The build plane is not a face angle of the golf club head.

A process of manufacturing a golf club head that includes the steps of generating, via an additive manufacturing process, a printed part that includes the steps of printing a material, layer by layer, along a build plane and creating at least one blow through aperture that allows fluid to flow through an internal cavity of the printed part. The build plane is offset from a ground plane by between about 5 degrees and about 160 degrees. The ground plane is defined as a horizontal plane parallel to the ground when the golf club head is at address. The process also includes the steps of excavating the printed part by forcing excess material out from within the internal cavity using the at least one blow through aperture and removing excess material formed at one or more material deposits disposed along the printed part golf club head.

A process of manufacturing a golf club component includes spreading a thin layer of metal powder over a build plane defined over a build platform and bonding, using a laser, portions of the thin layer of metal powder. The spreading and bonding are repeated until the golf club component is formed. The golf club component comprises a lattice structure positioned within an internal cavity of the golf club component and the lattice structure is interrupted by a solid portion that extends along a bottom side of the golf club component from a toe region of the golf club component to a location between the toe region and a heel region of the golf club component.

An iron-type golf club includes an iron-type golf club head formed of metal by an additive manufacturing process. The iron-type golf club head includes a front side, a rear side, a bottom side, a top side, a toe side, and a heel side, and a body that defines a medial region between a toe region and a heel region. The iron-type golf club head also includes a first plane that extends orthogonal to a ground plane and separates the toe region from the medial region, and a second plane that extends orthogonal to the ground plane and separates the heel region from the medial region. A front face extends along the front side from the toe region, through the medial region, and into the heel region, and the front face and the body are formed of sintered metal by the additive manufacturing process.

A variable thickness face plate for a golf club head includes a peripheral edge having an upper peripheral edge and a lower peripheral edge, and a plurality of regions of constant thickness defined by an internal surface of the face plate. The plurality of regions of constant thickness include a first subset of regions of constant thickness being disposed along a first horizontally-extending path proximate the upper peripheral edge, the first horizontally-extending path being disposed radially inward from and parallel to the upper peripheral edge, and a second subset of regions of constant thickness being disposed along a second horizontally-extending path proximate the lower peripheral edge, the second horizontally-extending path being disposed radially inward from and parallel to the lower peripheral edge.

Golf club weight

A golf club head includes a body and an insert. The body defines a top side, a toe side, and a heel side, and includes a sole extending between the toe side and the heel side at a location on the body opposite to the top side. The body defines an internal volume defined between a ball-striking face and an internal wall. The insert is arranged within the internal volume and is formed layer by layer via an additive manufacturing process. The insert includes a lattice structure arranged between a rear surface of the ball-striking face and the internal wall. The lattice structure is in engagement with the rear surface and formed integrally with the ball-striking face and the internal wall.

Systems and methods for additive manufacturing of a golf club having an insert structure

A process of manufacturing a face insert of a golf club head that includes the steps of forming, via an additive manufacturing process, a mold insert that includes a lattice structure or a ribbed structure protruding therefrom, creating a mold from the mold insert formed via the additive manufacturing process, and molding an insert from the mold insert.

A golf club head includes a body formed layer by layer and having a topline, a sole, and an internal cavity arranged between the topline and the sole. The golf club head further includes at least one aperture formed through at least one of a hosel extending from the body, a rear surface of the body, and a toe portion of the body. The at least one aperture is configured to form a flow path that extends along the internal cavity and the at least one aperture.

A headcover for a golf club includes a body formed layer by layer upon a build plane during an additive manufacturing process. The body defines a chamber adapted to receive a golf club head and includes a heel end, a toe end, and a plurality of sidewalls. The headcover further includes a lattice structure formed unitarily on a portion of the body during the additive manufacturing process. The lattice structure extends over at least a portion of each of the plurality of sidewalls and the toe end of the body.
