Abstract
According to examples, machine-readable instructions in a computer-readable medium may cause a processor to generate code representing a cavity to be formed in an object, generate code representing a first lattice structure to be formed in the object directly above the cavity, and generate code representing a second lattice structure to be formed in the object in an area adjacent to the first lattice structure, in which the first lattice structure may be stiffer than the second lattice structure. In addition, the processor may output the generated codes, in which a three-dimensional (3D) fabrication system may fabricate the object according to the generated codes.
Claims16
A non-transitory computer-readable medium storing instructions that when executed by a processor, cause the processor to:
- generate code representing a compressible cavity to be formed in an object, such the compressible cavity compresses under sufficient compression of the object responsive to a corresponding applied load;
- generate code representing a first lattice structure to be formed in the object directly above the compressible cavity, wherein responsive to the corresponding applied load, the compressible cavity compresses prior to the first lattice structure compressing;
- generate code representing a second lattice structure to be formed in the object in an area adjacent to the first lattice structure, wherein the first lattice structure is stiffer than the second lattice structure;
- and
- output the generated codes, wherein a three-dimensional (3D) fabrication system is to fabricate the object according to the generated codes.
A method comprising:
- determining, by a processor, a height of a compressible cavity and a height of a first lattice structure in a first section of a shoe midsole to be fabricated, wherein
- the compressible cavity and the first lattice structure are to cause the first section to absorb a first load level, the first lattice structure to be fabricated directly above the compressible cavity, and
- the compressible cavity compresses under sufficient compression of the first section of the shoe midsole responsive to a corresponding applied load, where responsive to the corresponding applied load, the compressible cavity compresses prior to the first lattice structure compressing;
- determining, by the processor, a dimension of elements in the first lattice structure that is to cause the first lattice structure to have a first stiffness level;
- determining, by the processor, a dimension of elements in a second lattice structure that is to cause the second lattice structure to have a second stiffness level, wherein the second lattice structure is to be fabricated adjacent to the first lattice structure;
- generating, by the processor, codes representing the compressible cavity, the first lattice structure, and the second lattice structure;
- and
- causing a three-dimensional (3D) fabrication system to fabricate the shoe midsole according to the generated codes.
A three-dimensionally (3D) printed object comprising:
- a first lattice structure;
- a compressible cavity formed beneath the first lattice structure, such the compressible cavity compresses under sufficient compression of the 3D printed object responsive to a corresponding applied load, wherein responsive to the corresponding applied load, the compressible cavity compresses prior to the first lattice structure compressing;
- a second lattice structure formed in an area adjacent to the first lattice structure, wherein the first lattice structure is stiffer than the second lattice structure.
