Abstract: In an example, three-dimensional (3D) models of objects are combined for additive manufacturing. Two-dimensional (2D) slices are determined for each 3D model. If the 2D slices are determined to be complete, the 2D slices are combined according to a Boolean operation to generate combined 2D slices printable by an additive manufacturing system.

Abstract: Examples disclosed herein relate to selecting a 3D printing parameter based on voxel property association and conflict resolution. In one implementation, a processor assigns properties to a voxel of a 3D print object based on a first and second zone including the voxel and a condition of a first property associated with the first zone and a condition of a second property associated with the second zone. The processor may update the assigned properties to resolve conflicts between the properties and select a 3D printing parameter based on the assigned properties.

Abstract: A computer program product for generating data for a three-dimensional (3D) printable object includes a computer readable storage medium. The computer readable storage medium includes computer usable program code embodied therewith. The computer usable program code, when executed by a processing device converts mesh data into a volumetric voxel data set. The voxel data set is organized as an N-ary tree defining at least a portion of the 3D printable object. The computer usable program code converts the N-ary tree of the voxel data set into print instructions defining a truss structure, and prints the 3D object including the truss structure.

Abstract: One example includes a non-transitory machine readable storage medium including voxels organized by an octree and at least one quad-tree index. The octree defines an object to be three-dimensionally printed and includes a list of nodes for each depth of the octree where each node includes nodal content representing at least one voxel. The at least one quad-tree index is to index at least one node of the octree and has a depth less than or equal to a maximum resolved depth. The at least one quad-tree index is to be accessed by computer executable instructions to retrieve nodal content from the octree to control a processor to process the object to be three-dimensionally printed.
