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.

Publication number: 20210260828Abstract: A method for carrying out additive manufacture while regulating material consumption, comprises making a digital representation of at least part of an object for printing, the representation comprising a plurality of voxels, and then identifying voxels which are flexible in respect of being able to consist of any one of at least two available materials. A balanced material consumption policy is then used to choose between the available materials so as to ensure that as far as possible, different materials are evenly used and wastage is minimized. Finally the object is printed with the selected materials.Type: ApplicationFiled: May 7, 2021Publication date: August 26, 2021Applicant: Stratasys Ltd.Inventors: Avraham TEKEN, Boris BELOCON

Patent number: 9688020Abstract: Embodiments of the present invention are directed to a system and method for reusing surplus material generated by an Additive Manufacturing system in the process of manufacturing a 3-dimensional (3D) object. Surplus material removed from deposited layers and purged material used for printing head maintenance are transferred to back to the printing system to be deposited within subsequent layers. The reusable material may be deposited within the boundaries of a cross section of the 3-dimensional object to become part of 3D object or outside the boundaries of a cross section of the 3-dimensional object as part of the support construction, which is removed from the finished product. According to embodiments of the invention, a portion of the waste material for disposal may be deposited and cured layer by layer to form a waste block, concurrently with printing the layers of the 3D dimensional object. The fully cured waste block may be then disposed of in a safe manner.Type: GrantFiled: December 21, 2011Date of Patent: June 27, 2017Assignee: STRATASYS LTD.Inventors: Avraham Teken, Boris Belocon
