权利要求：
1. A basketball comprising: a single integrally formed unitary body comprising: first layer comprising an inner lattice; second layer comprising an outer lattice and surface strips; and radial beams interconnecting the first layer and the second layer.
2. The basketball of claim 1, wherein the outer lattice is lobular with a plurality of lobes joined along the surface strips, and/or wherein the inner lattice is spherical and non-lobular, or wherein the inner lattice is lobular.
3. The basketball of claim 1 or 2, wherein the radial beams comprise a first number of the radial beams interconnecting the first layer and the second layer beneath the surface strips and a second number of the radial beams interconnecting the first layer and the second layer circumferentially between the surface strips and wherein each of the first number of radial beams has a first height and wherein each of the second number of radial beams has a second height greater than the first height.
4. The basketball of claim 3, wherein each of the first number of radial beams has a first thickness and wherein each of the second number of radial beams has a second thickness less than the first thickness, optionally wherein the radial beams comprise a third number of the radial beams interconnecting the first layer and the second layer in circumferential regions between the surface strips, each of the third number of radial beams having the second height and a third thickness greater than the second thickness.
5. The basketball of any preceding claim, wherein the radial beams comprise a first number of the radial beams interconnecting the first layer and the second layer inward of the surface strips and a second number of the radial beams interconnecting the first layer and the second layer circumferentially between the surface strips and wherein each of the first number of radial beams has a first thickness and wherein each of the second number of radial beams has a second thickness less than the first thickness.
6. The basketball of any preceding claim, wherein the outer lattice comprises outer lattice beams having flat outer surfaces, and/or wherein the outer lattice comprises an outer textured surface.
7. The basketball of any preceding claim, wherein the radial beams have a uniform thickness between the inner lattice and the outer lattice.
8. The basketball of any preceding claim, wherein the inner lattice and the outer lattice each comprise a two-dimensional hexagonal lattice, and/or wherein the inner lattice and the outer lattice comprise cells having a center-to-center distance of at least 5 mm and no greater than 12 mm.
9. The basketball of any preceding claim, wherein the inner lattice comprises inner lattice beams having a thickness of at least 1 mm and no greater than 5 mm and wherein the outer lattice comprises outer lattice beams having a thickness of at least 0.8 mm and no greater than 3.5 mm.
10. The basketball of any preceding claim, wherein the single integrally formed unitary body is formed from a material having material properties, measured as injection molded, of: a density of at least 0.9 g/cm3 and no greater than 1.2 g/cm3, a shore A durometer of at least 80 and no greater than 92; a flexural modulus of at least 80, a tensile modulus of at least 50, and elongation percentage of at least 150% and a rebound resilience of at least 50% as measured pursuant to ASTM D7121/DIN 53512 DIN 53516.
11. The basketball of any preceding claim, further comprising an outer skin over an outer surface of the outer lattice, optionally wherein the outer skin is imperforate, optionally wherein the outer skin is transparent or translucent.
12. The basketball of any preceding claim, further comprising an inner skin formed on an inner surface of one of the inner lattice and the outer lattice.
13. The basketball of any preceding claim, wherein the basketball has a circumference of at least 742 mm and no greater than 759 mm, a mass of at least 567 g and no greater than 628 g, and a rebound of at least 1320.8 mm (52 inches) and no greater than 1346.2 mm (53 inches).
14. A computer program comprising computer executable instructions that, when executed by a processor, cause the processor to control an additive manufacturing apparatus to manufacture a basketball of any preceding claim.
15. A method of manufacturing a basketball of any one of claims 1 to 13, the method comprising: obtaining an electronic file representing a geometry of the basketball; and controlling an additive manufacturing apparatus to manufacture, over one or more additive manufacturing steps, the basketball according to the geometry specified in the electronic file.
