Abstract: According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions that when executed by the processor are to cause the processor to access a reduced resolution three-dimensional (3D) model file of an object to be built in a build bed of a 3D printing system, the reduced resolution 3D model file comprising a reduced resolution file of a first resolution 3D model file of the object. The instructions may also cause the processor to determine a packing arrangement for the object and a plurality of other objects to be built in the build bed through use of the reduced resolution 3D model file and output the determined packing arrangement for the 3D printing system to print the object and the other objects.

Abstract: Systems and methods are described herein to determine positive or negative displacement distances for each pixel of an image of a graphical element. A displacement subsystem may determine surface displacement distances based on a function of a distance of each pixel to a nearest edge pixel of the image of the graphical element. A mapping subsystem may generate a surface displacement map of the graphical element to be applied to a surface of a three-dimensional object. The surface displacement map may be used to generate a mesh file and/or transmitted to a three-dimensional printing for printing on a surface of an object.

Abstract: A method for generating 3D printing points may include obtaining a Steiner patch that is part of a tessellation approximation of the 3D object, determining a parametric curve of a slicing plane and the Steiner patch, determining a classification of the parametric curve, sampling, based upon the classification, first and second points spaced by a parametric spacing along the parametric curve, determining a Euclidean spacing of the first and second points, and comparing the Euclidean spacing to a predefined spacing threshold. In response to the Euclidean spacing failing to satisfy the predefined threshold, sampling a third point along the parametric curve between the first and second points, generating 3D printing points in Euclidean space for the object based upon the first point, second point and third point sampled along the parametric curve.
