  • Patent number: 11904409
    Abstract: Additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position of the build part relative to an additive manufacturing instrument. The geometrical characteristics include an angle of incidence between a beam line extending from a beam emitter and a surface normal of a respective skin of the corresponding segment proximate to the beam line. The one or more processors select, based on the determined geometrical characteristics, a first set of beam parameters for forming a first segment of the build part and a second set of beam parameters for forming a second segment of the build part. At least one of the beam parameters in the second set differs from the beam parameters in the first set.

  • Patent number: 11772195
    Abstract: An additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position relative to an additive manufacturing instrument. The one or more geometrical characteristics include an angle of incidence between a beam line extending from a beam source and a surface normal of a respective skin of the corresponding segment proximate to the beam line. The one or more processors are configured to control the additive manufacturing instrument, based on the one or more geometrical characteristics, to direct focused energy beams from a first orientation relative to the build part to form a first segment of the segments of the build part and to direct focused energy beams from a second orientation relative to the build part to form a second segment of the segments of the build part.

  • Patent number: 11766745
    Abstract: An additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position of the build part relative to an additive manufacturing instrument. The one or more geometrical characteristics include an angle of incidence between a beam line extending from an electromagnetic energy source of the additive manufacturing instrument and a surface normal of a respective skin of the corresponding segment proximate to the beam line. The one or more processors are configured to determine, based on one or more geometrical characteristics of the segments at the candidate position, one or more locations of support material to be formed adjacent the build part during a build process of the build part.

  • Patent number: 11073824
    Abstract: An additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position of the build part relative to a platform. The one or more processors are configured to generate a quality score for each of the segments at the candidate position based on the one or more geometrical characteristics, The one or more processors are also configured to generate a simulation model of the build part at the candidate position for display. The simulation model includes graphic indicators corresponding to each of the segments. The graphic indicators are representative of the quality scores of the corresponding segments.
