Patent number: 11897187Abstract: A method of additive manufacturing of a three-dimensional object includes sequentially dispensing and solidifying a plurality of layers. The plurality of layers may be formed with a plurality of different colored model materials, a flexible material arranged in a configured pattern to form a sacrificial structure at least partially encompassing the object, and a soft material. The soft material is arranged in a configured pattern to provide separation between the model material and the sacrificial structure. The plurality of different colored model materials is arranged in a configured pattern corresponding to the shape and color definition of the object.Type: GrantFiled: June 28, 2020Date of Patent: February 13, 2024Assignee: Stratasys Ltd.Inventors: Mayan Rumbak, Eduardo Napadensky, Gavish Mida

Publication number: 20230071980Abstract: A method of additive manufacturing a three-dimensional object by layerwise deposition of a building material with an inkjet printing system comprising a print head and a building tray, comprises calculating a weighting value for each nozzle, then for each layer obtaining a 2-D map of the layer, comprising active pixels at building material dispensing positions; obtaining a Data Correction Filter (DCF) including a height map of the previous layer, comparing the data of the 2D map to the data of the DCF at each position and determining if the nozzle at that position should dispense, then printing the layer, updating the weighting values and adjusting the position of the print head vis a vis the printing tray. The above is repeated until the three-dimensional object is printed.Type: ApplicationFiled: November 15, 2022Publication date: March 9, 2023Applicant: Stratasys Ltd.Inventors: Mayan RUMBAK, Eduardo NAPADENSKY, Raffy SARFATI, Gavish MIDA

Publication number: 20230001631Abstract: A method of layerwise fabrication of a three-dimensional object is disclosed. The method comprises, for each of at least a few of the layers: dispensing at least a first modeling formulation and a second modeling formulation to form a core region using both the first and the second modeling formulations, and at least one envelope region at least partially surrounding the core region using one of the first and the second modeling formulations but not the other one of the first and the second modeling formulations. The method can also comprise exposing the layer to curing energy. The first modeling formulation is characterized, when hardened, by heat deflection temperature (HDT) of at least 90° C., and the second modeling formulation is characterized, when hardened, by Izod impact resistance (IR) value of at least 45 J/m.Type: ApplicationFiled: September 1, 2022Publication date: January 5, 2023Applicant: Stratasys Ltd.Inventors: Diana RAVICH, Ophira MELAMED, Avraham TEKEN, Gavish MIDA, Avraham LEVY, Cesar M.
