Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing instructions for printing of 3D objects. One of the methods includes obtaining i) information regarding one or more geometric features of a 3D model of an object to be printed by an extrusion-based 3D printer and ii) process parameters for use in printing; generating, by the computer-aided manufacturing environment, print instructions for the printing of the 3D object by the extrusion-based 3D printer in a series of multiple layers, wherein modified process parameters are generated as part of the print instructions by modifying the obtained process parameters for a proper subset of layers based on the information regarding the one or more geometric features of the 3D model of the object; and providing, by the computer-aided manufacturing environment, the print instructions comprising the modified process parameters to operate the extrusion-based 3D printer to print the object.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for designing and manufacturing physical objects including lattice structures include, in one aspect, a method including: providing a three-dimensional model including a dual representation of a lattice structure, wherein both a shell mesh model and a solid body model of the lattice structure are producible from an additional model of the lattice structure, and beams of the lattice structure in the solid body model are hollow; performing numerical simulation using at least the shell mesh model of the dual representation to produce a current numerical assessment; modifying the additional model of the dual representation based on the current numerical assessment; repeating the performing and the modifying one or more times until the numerical simulation indicates the lattice structure satisfies at least one response requirement; and providing at least the solid body model for use in manufacturing the lattice structure.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for designing and manufacturing physical objects including lattice structures include, in one aspect, a method including: obtaining a skeleton model of a lattice structure, constructing a control point frame surface model using the skeleton model, generating a shell mesh model of the lattice structure using the control point frame surface model, performing numerical simulation of a physical object using the shell mesh model included within a 3D model of the physical object to produce an assessment, modifying the skeleton model or the control point frame surface model based on the assessment to change the lattice structure until it satisfies at least one response requirement, producing from the control point frame surface model a solid body model of the lattice structure hollow beams, and providing at least the solid body model for use in manufacturing a hollow lattice structure.
