Abstract: The present invention is a method for manufacturing a golf ball including a core, at least one intermediate layer, and a cover, the core being formed of a rubber material, the intermediate layer being formed of a resin composition, and the cover being formed of a urethane resin material, the method including: a step (1) of forming an intermediate layer-encased sphere by encasing the core with the at least one intermediate layer; a step (2) of subjecting the intermediate layer-encased sphere to a heat treatment at a temperature of at least a melting point of a base resin of the resin composition of the intermediate layer and less than 160° C.; and a step (3) of thereafter forming a cover-encased sphere by encasing the intermediate layer- encased sphere with the cover.

Abstract: A method of forming a pickleball in an additive manufacturing system includes selecting one of a polymer or liquid resin material from which the pickleball is to be additively manufactured. A computer file is provided containing computer readable instructions for the automated additive manufacturing of a computer generated model of the pickleball, the instructions including a definition of the geometric shape of the pickleball divided into a plurality of successively layered cross sectional slices. A 3D printer executes the instructions to initiate an automated additive manufacturing of a physical pickleball from the selected polymer, corresponding to the design of the computer generated model. The 3D printer creates solid cross sections of the pickleball in the selected material that are progressively and integrally bonded together and correspond to the successively layered cross sectional slices of the pickleball design, to form a complete pickleball.

Abstract: A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.

Abstract: The presently disclosed subject matter is directed to a golf ball providing improve play characteristics. The disclosed golf ball includes an outer cover comprising a plurality of divots. The disclosed golf ball further includes a central core comprising one or more lightweight materials, such as aerogel. The combination of the lightweight core and the unique divots enable the golf ball to go farther and straighter when hit by the golfer, thereby providing increased performance.

Abstract: In a method for providing a three-dimensional object, the method includes the steps of providing a representation of the three-dimensional object; determining a polygon mesh of a polyhedral resembling the object, wherein the polyhedral fits within the object; determining a surface difference between an outer surface of the object and an outer surface of the polyhedral; defining a relief layer corresponding to the polygon mesh based on said surface difference; instructing a printing assembly to provide the relief layer; and folding the relief layer in accordance with the polygon mesh to form the polyhedral resembling the three-dimensional object. Thus, using a printing assembly to print two-dimensional layers, a three-dimensional object may be provided or at least approximated.

Abstract: Described are methods for manufacturing an outer layer for a panel of a ball, in particular of a football, an outer layer manufactured with such a method as well as a panel and a ball comprising such an outer layer. The method includes shaping a sheet of material in a mold, wherein the mold is formed in such a way that during shaping, the sheet of material assumes a three-dimensional shape of the outer layer of the panel. Moreover, the method includes creating first textures in at least a first partial region on a first side of the sheet of material and creating second textures in at least a second partial region of the sheet of material.
