Estimating physical property of 3D printed parts

Abstract:

Methods, systems, and apparatus, including medium-encoded computer program products, for estimating the physical properties of 3D printed objects that include: obtaining a three dimensional (3D) model of a 3D object to be manufactured by a 3D extrusion printer; obtaining at least a portion of tool path data for the 3D extrusion printer to build the 3D object in accordance with the 3D model; creating unit cell geometry from the at least a portion of tool path data using at least one limitation on one or more unit cells of the unit cell geometry with respect to an aspect of the 3D extrusion printer's build of the 3D object; generating a numerical simulation of one or more microstructural properties of the 3D object to be built using the unit cell geometry; and estimating one or more macroscale properties, of the 3D object to be built, from the numerical simulation.
