  • Patent number: 11926101
    Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, may cause the processor to identify a property of a portion of a three-dimensional (3D) part to be fabricated and determine, based on the identified property, a thermal value associated with the portion. The instructions may also cause the processor to, based on the determined thermal value, determine a first agent composition to be used to fabricate the portion and determine a second agent composition to be used to fabricate a section external and adjacent to the portion, in which the first agent composition and the second agent composition may be determined to cause the portion and the external section to be fabricated to have the identified property while maintaining the external section separate from the portion.

  • Patent number: 11760027
    Abstract: In some examples, an additive manufacturing system includes a dispensing device, an applicator, a thermal energy source, a thermal imaging device, and a controller. The controller is to cause the dispensing device to deposit a layer of build material and cause the applicator to apply the fusing agent to form an object portion and to apply the detailing agent to form a reference portion in the layer of build material. The controller is to cause the thermal energy source to heat the reference portion and to heat and fuse the object portion and cause the thermal imaging device to measure a temperature of the reference portion. The controller is to regulate a power level of the thermal energy source based on a comparison between the temperature of the reference portion and a set-point for the reference portion, which is based on a target temperature for the object portion.

  • Publication number: 20230191492
    Abstract: In some examples, a system receives measurement data obtained based on a non-destructive imaging of an identifiable structure within a three-dimensional (3D) object formed using an additive manufacturing machine, the identifiable structure formed based on control of a characteristic of a build material of a first internal object portion relative to a characteristic of the build material in a second internal object portion, the first and second internal object portions being within the 3D object. The system determines, based on the measurement data, a deviation of a physical property of the identifiable structure from a target physical property, and outputs information indicating the deviation.
