Claim 0:
1. An additive manufacturing system comprising:
a beam emitter; and a control unit comprising one or more processors and a memory, the 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 build platform of an additive manufacturing instrument, wherein the one or more geometrical characteristics include an angle of incidence between (i) a beam line extending from the beam emitter of the additive manufacturing instrument to a surface layer of the build part and (ii) a surface normal vector of a respective skin of the corresponding segment proximate to the beam line, wherein the skin of the corresponding segment is a side surface of one or more layers of the build part immediately below the surface layer,
wherein the one or more processors are configured to select, based on the one or more geometrical characteristics of the segments including the angle of incidence, a first set of beam parameters to be used by the beam emitter to emit first focused energy beams that form a first segment of the segments of the build part and a second set of beam parameters to be used by the beam emitter to emit second focused energy beams that form a second segment of the segments of the build part, wherein at least one of the beam parameters in the second set differs from the beam parameters in the first set.
