Patent number: 11704858Abstract: A method of processing data for additive manufacturing of a 3D object comprises: receiving graphic elements defining a surface of the object, and an input color texture to be visible over a surface of the object; transforming the elements to voxelized computer object data; constructing a 3D color map having a plurality of pixels, each being associated with a voxel and being categorized as either a topmost pixel or an internal pixel. Each topmost pixel is associated with a group of internal pixels forming a receptive field for the topmost pixel. A color-value is assigned to each topmost pixel and each internal pixel of a receptive field associated with the topmost pixel, based on the color texture and according to a subtractive color mixing. A material to be used during the additive manufacturing is designated based on the color-value.Type: GrantFiled: August 14, 2022Date of Patent: July 18, 2023Assignee: Stratasys Ltd.Inventors: Yoav Bressler, Shai Lipowitch, Shahar Klinger, Mayan Rumbak

Patent number: 10562318Abstract: Embodiments of the invention relate to techniques whereby sufficient compensation is provided to counteract the deleterious effects of a malfunctioning nozzle (i.e. which might create a white streak within the printed ink image) in a manner that is faithful to/harmonious with the underlying AM or FM screening. In this manner, it is possible to minimize the negative impact a failed or malfunctioning nozzle has upon the printed ink image.Type: GrantFiled: November 5, 2018Date of Patent: February 18, 2020Assignee: LANDA CORPORATION LTD.Inventors: Alon Siman-Tov, Shahar Klinger, Mattetyahu Litvak, David Tal

Patent number: 10410100Abstract: Apparatus and methods for printing multi-level and multi-color digital image are disclosed herein. In some embodiments, first and second level AM half-tone screens are respectively applied to first and second multi-level color-components of the multi-level and multi-color input digital image to respectively generate first and second target binary images. The first and second target binary images are printed respectively using first and second inks (e.g. of different colors) onto a common surface. Specific properties of the AM half-tone screens as well as techniques for producing the AM half-tone screens are disclosed herein. In some embodiments, the techniques overcome objectionable textures derived from rounding errors in divisional of conventional AM supercells.Type: GrantFiled: November 14, 2018Date of Patent: September 10, 2019Assignee: LANDA CORPORATION LTD.Inventors: David Tal, Shahar Klinger

Patent number: 9749497Abstract: There is provided an ink-deposition device suitable for depositing ink on a target surface and a printing system comprising the same. In operation in a printing system, the ink-deposition device can convert digital images into ink images on the target surface using pixel-masks and methods as disclosed herein. Advantageously, the ink-deposition device, the printing system comprising it and the methods of using the same can reduce or prevent the occurrence of some undesired ink-formations typically governed by the respective physical and/or chemical properties of the surface and ink being used or mitigate their effect on print quality. Application of the pixel-image mask yields a binary image that exhibits pixel-clusters with stochastically distributed centroids.Type: GrantFiled: January 22, 2015Date of Patent: August 29, 2017Assignee: LANDA CORPORATION LTD.Inventors: Mattetyahu Litvak, Shahar Klinger, Alon Siman Tov, Avraham Guttman
