Abstract

A method for flexible functionally tailorable slicing for additive manufacturing includes the steps of receiving and parsing an input model of an object to be additively manufactured; reconstructing a domain boundary of the object; computing individual layer boundaries of the object; constructing, for each layer, layer domains from respective enclosing boundaries; computing, for each layer, a perimeter shell and a volumetric infill by finding level sets of a field function selected by a user; collecting and arranging into a coherent sequence each perimeter shell and volumetric infill; and formatting the coherent sequence as motion commands for an additive manufacturing system.
