    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.

    Abstract: A method of three-dimensional (3D) printing is provided. Print data is received, which defines patterns of at least one agent to be applied to a layer of build material. These patterns are at least partially based on a 3D model of at least one object to be generated. The print data is processed to determine regions which are distant from said patterns. The print data is modified to add a further pattern of a detailing agent to be selectively applied to the layer of build material to generate fracture regions in a processed volume of build material.

    Abstract: Object model data modification is described in which object model data defining a three dimensional model to be generated by a three-dimensional printer may be obtained. Data relating to a first sensitive portion of the model may be obtained, the first sensitive portion representing a portion of the model to be concealed. Modified object model data in generated, the modified object model data including a first version of the three dimensional model that is represented in a first pre-processing application without exposing the first sensitive portion, and including the first object model data defining the three dimensional model for printing by a three-dimensional printer.
