Patent number: 11673318Abstract: A method employs a first polymeric material to deposit first and second pattern layers laterally shifted from each other such that laterally shifted pattern layers form between them an empty volume with a variable cross-section that varies along with the first and second pattern layers. A second polymeric material is cast in the empty volume between the first and second pattern layers to cast a complex-shaped 3D object identical in shape to the empty volume between the first and second pattern layers. Radiation is applied to cure the first and second polymeric materials. The first polymeric material is a water breakable material composition including acrylamide, methacrylamide, acrylate, acrylic acids, and acrylic acid salts, hydroxy(meth)acrylate, carboxy(meth)acrylate, acrylonitrile, carbohydrate monomers, methacrylate and polyfunctional acrylics.Type: GrantFiled: June 2, 2021Date of Patent: June 13, 2023Assignee: MASSIVIT 3D PRINTING TECHNOLOGIES LTD.Inventor: Shai Garty

Patent number: 10167409Abstract: The current three-dimensional object manufacturing technique relies on the deposition of a pseudoplastic material in gel aggregate state. The gel flows through a deposition nozzle because the applied agitation and pressure shears the bonds and induces a breakdown in the material elasticity. The elasticity recovers immediately after leaving the nozzle, and the gel solidifies to maintain its shape and strength.Type: GrantFiled: November 17, 2015Date of Patent: January 1, 2019Assignee: MASSIVIT 3D PRINTING TECHNOLOGIES LTDInventors: Nataly Lisitsin, Yoav Miller, Igor Yakubov, Moshe Uzan, Victoria Gordon
