Abstract: Described is an apparatus for the manufacture of 3D objects from composite materials. The apparatus includes an adjustable support platform formed by a plurality of individually adjustable support columns; at least one material extrusion nozzle configured to extrude a composite material of a manufactured 3D object; and at least one robotic arm configured to operate a plurality of end-effector tools. The at least one robotic arm maintains at least an extrusion nozzle perpendicular to surface of the extruded 3D object's surface segment.

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 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.
