Patent number: 11872828Abstract: A method of printing a three-dimensional (3D) color object, layer-by-layer, comprises: obtaining a 3D CAD specification defining a 3D geometry and a surface color distribution for the color object to be printed, defining regions on a surface of the color object; defining colors for each region based on the CAD specification; determining, using the 3D geometry of the specification, conditions applying at respective regions that are liable to cause color variation, such that using the colors as defined at the respective regions may give rise to a coloration error; selecting color corrections defined for respective determined conditions; correcting the defined colors; and printing the 3D color object with the color corrections.Type: GrantFiled: July 8, 2021Date of Patent: January 16, 2024Assignee: Stratasys Ltd.Inventors: Daniel Dikovsky, Stanislav Shtilerman, Yoav Bressler

Publication number: 20220040763Abstract: A method to define construction of a green compact with at least one object embedded therein is disclosed. The method includes receiving three-dimensional data defining the at least one object and identifying a planar surface in the at least one object based on the three-dimensional data. Orientation of the at least one object is defined so that the planar surface extends at least partially over a Z height of the green compact. A mask pattern is defined per layer to form the at least one object in the defined orientation by an additive manufacturing process with powder material.Type: ApplicationFiled: December 16, 2019Publication date: February 10, 2022Applicant: Stratasys Ltd.Inventors: Shai HIRSCH, Yehoshua SHEINMAN, Stanislav SHTILERMAN

Patent number: 10318654Abstract: A method for slicing a three-dimensional model for printing of a corresponding object by a 3D printer, comprises: obtaining the envelope of the object as polygons, then for each region of a predefined work area within the slicing plane: identifying the closest polygon of said envelope that is positioned above said respective pixel; where no polygon is identified, then marking a corresponding region as a no-print region; if the direction vector of said closest above polygon has a positive component in the Z direction, then marking said corresponding region as a model region; and if the direction vector of said polygon has a negative component in the Z direction, then marking the region as a support region, and printing accordingly. An advantage of the above procedure is that the slicing, and in addition texture mapping, can be efficiently carried out on a graphics card or GPU.Type: GrantFiled: March 13, 2014Date of Patent: June 11, 2019Assignee: Stratasys Ltd.Inventor: Stanislav Shtilerman
