Abstract: A method for producing three-dimensional parts, which includes printing the three-dimensional parts and associated support structures onto soluble build sheets, marking each three-dimensional part with information relating to the three-dimensional part, and removing the associated support structures and the soluble build sheets from the printed three-dimensional parts with an aqueous solution using a support removal process. The markings remain applied to the three-dimensional parts after the support removal process, and preferably do not detract from aesthetic qualities of the three-dimensional parts.

Abstract: A method for printing a three-dimensional part in an additive manufacturing process, which includes calculating surface plane angles relative to one or more of the coordinate axes as a function of surface area of the surface geometry, calculating a build score for each coordinate axis as a function of the calculated surface plane angles, and selecting an orientation for the digital model in the coordinate system based at least in part on the calculated build scores. The build scores preferably predict which part orientations are likely to provide good surface quality for the printed three-dimensional part.
