Abstract

Material is incrementally deposited using material directed toward a deposition zone. The scan path of the directed material is controlled according to a path plan derived to reduce derivation from an ideal uniform temperature profile for the deposition during the deposition process. A path plan having angled scan passes that intersect (or overcross one another), for example in a mirrorbox path plan, is preferred.
