Abstract
According to examples, an apparatus may include a plurality of structures formed of fused sections of build material particles and a plurality of porous sections supported by the plurality of structures. The plurality of porous sections may be formed of partially-fused build material particles, in which the partially-fused build material particles may include build material particles that may be partially fused together to cause the plurality of porous sections to have at least a predefined porosity level.
Claims12
A method performed by a processor and comprising:
- determining a porosity level of a porous section of a screen apparatus to be fabricated via an additive manufacturing process in which:
- on a layer-by-layer basis, build material is deposited and then one or more print agents are selectively applied onto the build material;
- and
- energy is applied to the build material to selectively fuse the build material together;
- determining one or more respective patterns at which the one or more print agents are to be selectively applied to the build material to provide controlled thermal bleeding of the build material upon application of the energy such that the build material is partially fused together past where at least one of the one or more print agents are selectively applied to the build material to realize the determined porosity level;
- and
- causing an additive manufacturing apparatus to additively manufacture the screen apparatus via the additive manufacturing process using the determined one or more respective patterns during the selective application of the one or more print agents.
A non-transitory computer-readable storage medium storing instructions executable by a processor to perform processing comprising:
- determining a porosity level of a porous section of a screen apparatus to be fabricated via an additive manufacturing process in which:
- on a layer-by-layer basis, build material is deposited and then one or more print agents are selectively applied onto the build material;
- and
- energy is applied to the build material to selectively fuse the build material together;
- determining one or more respective patterns at which the one or more print agents are to be selectively applied to the build material to provide controlled thermal bleeding of the build material upon application of the energy such that the build material is partially fused together past where at least one of the one or more print agents are selectively applied to the build material to realize the determined porosity level;
- and
- causing an additive manufacturing apparatus to additively manufacture the screen apparatus via the additive manufacturing process using the determined one or more respective patterns during the selective application of the one or more print agents.
A system comprising:
- a processor;
- and
- a memory storing instructions executable by the processor to perform processing comprising:
- determining a porosity level of a porous section of a screen apparatus to be fabricated via an additive manufacturing process in which:
- on a layer-by-layer basis, build material is deposited and then one or more print agents are selectively applied onto the build material;
- and
- energy is applied to the build material to selectively fuse the build material together;
- determining one or more respective patterns at which the one or more print agents are to be selectively applied to the build material to provide controlled thermal bleeding of the build material upon application of the energy such that the build material is partially fused together past where at least one of the one or more print agents are selectively applied to the build material to realize the determined porosity level;
- and
- causing an additive manufacturing apparatus to additively manufacture the screen apparatus via the additive manufacturing process using the determined one or more respective patterns during the selective application of the one or more print agents.
