Abstract
An apparatus for manufacturing a three-dimensional article by additive manufacturing includes a processor and an information storage device. The information storage device includes a non-transient or non-volatile device storing software instructions. In response to execution by the processor, the software instructions cause the apparatus to: receive initial data defining the three-dimensional article having an outer surface, define a shell having the outer surface of the three-dimensional article and an opposing inner surface that defines an inner cavity, define a boundary in the inner cavity that further defines an outer lattice volume between the inner surface of the shell and the boundary and an inner volume inside the boundary, and define a lattice that fills the outer lattice volume.
