Abstract: Described is a method for manufacturing 3D objects from woven fabric-based composite materials. The method includes a movable mold used to manufacture a complete object by tiling the object, instead of using a single monolithic mold. The method includes using an easily configurable digital mold matrix for the tiling mentioned above and a calibration unit configured to set the desired shape of a strip of the digital mold matrix surface. A digital file provides the information required for building the digital mold surface. A movable and adjustable pins matrix form a configurable support surface of the digital mold matrix. The configurable support surface of the digital mold matrix receives and supports the material from which the 3D object is built while tiling.

Abstract: 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.

Abstract: Described is a method of manufacture of 3D objects from composite materials. The method includes the use of an extrusion nozzle configured to extrude the composite material, including a multistrand filament with a thixotropic acrylic matrix material surrounding the multistrand filament. Extruding a 3D object surface segment spanning in the air over at least a segment of a discontinuous work surface and operating concurrently a source of curing energy to pin and enhance the strength of a 3D object surface segment spanning in air. The 3D object extruded surface segment spanning in the air is sufficiently rigid and maintains its shape without the use of a mandrel.

Abstract: Described is a self-cleaning extrusion orifice assembly including an enclosure, a cylindrical body inserted into the enclosure and terminated by an extrusion orifice. The self-cleaning extrusion orifice assembly is operated by a pressurized air flow. The pressurized air flow flushes surfaces of some elements of self-cleaning extrusion orifice assembly removing debris that could be deposited on these surfaces. In addition, some elements of self-cleaning extrusion orifice assembly are configured to scrape extrusion process debris from the same surfaces.

Abstract: Described is a method and apparatus for manufacturing complex-shaped tubular or hollow 3D objects without using a mandrel. Instead of a mandrel, the shape of the composite object is determined locally by a roller that is placed according to the local geometry of the part at the point of layup. The use of rapidly curing resins allows “freezing’ of the composite strip immediately after layup.
