Golf ball components made using three-dimensional additive manufacturing systems

A golf ball having at least one three-dimensional piece, wherein the golf ball comprise an inner core and surrounding cover, the inner core being formed by a method comprising the steps of:

• a) providing a bath member having a bottom surface with an oxygen-permeable ultraviolet light-transparent window, wherein the bath contains ultraviolet light-polyrnerizable resin;
• b) projecting a sequence of ultraviolet light images through the window according to digital information to form the inner core on a support plate;
• c) continuously elevating the support plate and drawing the inner core out of the resin in the bath and curing the inner core, as a polymerization inhibition zone is created between the window and inner core being elevated on the support plate and as the images are projected through the window, the inner core having an interior portion and an outer portion connected via lattice structural members as a single piece, the inner portion outer portion, and structural member being made of the same material, such that the core contains air pockets encased within the lattice of the core.
