Abstract: 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.

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.

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: A method of forming a three-dimensional object by extrusion of a highly viscous pseudoplastic flame retardant material having a first viscosity and agitating the material to shear the pseudoplastic flame retardant material thereby decreasing the first viscosity to a second viscosity and to cause the pseudoplastic flame retardant material to flow. Adjacent layers of the extruded material are offset to form a cantilevered 3D object.

Abstract: An apparatus for 3D printing includes a support configured to support a 3D object to be printed. A material dispensing nozzle is configured to move relative to the support and dispense layers of material from which the 3D object is built. Movement of the material dispensing nozzle is a function of a gap and shell weak spaces between two neighbor layers to be printed.

Abstract: A method and apparatus for manufacturing of 3D objects. The apparatus includes a number of material deposition heads terminated by nozzles, of which one or two nozzles are configured to deposit a first material to form a first and second pattern layers. The pattern layers are laterally shifted from each other such that when the first and second pattern layers are deposited, a space (empty volume) with a varying cross section is formed. In some examples, two or more nozzles could be used to deposit the corresponding first and second pattern layers. The nozzles could move independent of each other.

Abstract: An additive manufacturing device is disclosed that enables the manufacturing of 3D objects at a short time. The device uses multiple writing heads to write simultaneously different segments of the object and thus complete the object manufacture in a shorter time as compared to a one head additive manufacturing device.
