Printing conductive elements
In an example, an apparatus includes processing circuitry comprising a model assessment module to identify an indication of a conductive element within object model data representing an object to be printed and a print instruction module to generate print instructions to generate the object. The print instructions may include an instruction to print conductive agent to form the conductive element and an instruction to print a fusing agent comprising an instruction to reduce an amount of fusing agent to be printed in a region of the conductive element compared to at least one other region of the object.
1. A method comprising:
identifying, by a processor and from object model data for a physical object, a first region of an object layer comprising an indication of a conductive element;
printing, using an additive manufacturing apparatus, the object layer comprising the first region comprising the conductive element, and a second region comprising an insulating composition;
applying, using the additive manufacturing apparatus, a first amount of at least one fusing agent to the object layer within the first region;
applying, using the additive manufacturing apparatus, a second amount of the at least one fusing agent to the object layer within the second region, wherein the first amount of the at least one fusing agent is selected to be less than the second amount of the at least one fusing agent based on identifying the first region as comprising the indication of the conductive element; and
fusing, using the additive manufacturing apparatus, at least one layer of build material from which the object layer is formed by controlling irradiation of the at least one fusing agent by the additive manufacturing apparatus in the first region and the second region.
2. The method of claim 1 , further comprising:
printing, using the additive manufacturing apparatus, a fusible conductive agent in the first region before applying the first amount and the second amount of the at least one fusing agent.
3. The method of claim 1 , further comprising:
controlling, by the processor, either or both of an irradiation time and an irradiation intensity during the irradiation of the at least one fusing agent by the additive manufacturing apparatus in the first region and the second region.
4. The method of claim 1 , further comprising:
controlling, by the processor, the irradiation of the at least one fusing agent by the additive manufacturing apparatus using a non-print pass.
5. The method of claim 1 , further comprising:
controlling, by the processor, the irradiation of the at least one fusing agent by the additive manufacturing apparatus based on the first amount of the fusing agent.
6. The method of claim 1 , wherein either:
the processor is part of an apparatus separate from the additive manufacturing apparatus; or
the processor is part of the additive manufacturing apparatus.
