1. An additive manufacturing system, comprising:
a build tool configured to deposit a feedstock material and/or deliver consolidation energy promoting consolidation of the feedstock material, within an accessible range defining a build space; and
a controller configured to:
determine a build trajectory through the build space, the build trajectory having (i) a plurality of layers, (ii) a combination of a raster and a spiral form within at least one of the plurality of layers, and (iii) a plurality of build points at which the feedstock material is deposited and/or the consolidation energy is delivered,
determine respective consolidation times of the feedstock material for one or more of the plurality of the build points,
determine, based at least in part on the determined consolidation times of the feedstock material, a deposition rate at which the feedstock material is deposited and/or consolidation energy is delivered to the feedstock material, and
cause the build tool to build an object in accordance with the determined build trajectory and the determined deposition rate.
