Claim 19:
20. 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 an angle of incidence of each of multiple segments of a build part at a candidate position of the build part relative to a platform on which the build part is to be build, the angle of incidence of each of the segments defined between (i) a beam line extending from the beam emitter of an 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 angles of incidence of the segments, 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, the second set of beam parameters including a greater offset beam parameter than the first set based on the angle of incidence of the second segment being greater than the angle of incidence of the first segment.
