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.
