Abstract: A printing head of a printing system may include an extruder, a nozzle, a rotation platform, an engine with a drive mechanism, and at least one curing module. The printing head is found in fluid communication with a feeding system to receive a resin material to be extruded out of the nozzle. The rotation platform comprises a rotary system configured for rotation in at least one axis. The engine and drive mechanism drive the rotation of the rotation platform. The curing module is coupled to rotate with the rotation platform. The curing module is configured to assist in the curing of the extruded resin material. The curing module and the rotation platform are operatively connected to a control system for controlling operation of the curing module and the rotation platform.

Abstract: A formulation for a photopolymer composite material for a 3D printing system includes an acrylate monomer or an acrylate oligomer, an inorganic hydrate, a reinforcing filler, a co-initiator, a thermal initiator, and an ultraviolet (UV) initiator. In the formulation the acrylate monomer or the acrylate oligomer may be between about 10.0-30.0 w % of the formulation. The thermal initiator may be between about 0.001-0.05 w %, the co-initiator may be between about 0.001-0.05 w %, and the UV initiator may be between about 0.001-0.2 w % of the formulation. A method of generating a formulation of a photopolymer composite material for use in a 3D printing system includes using an acrylate monomer or an acrylate oligomer, an inorganic hydrate, a reinforcing filler, a co-initiator, a thermal initiator, and an ultraviolet (UV) initiator.
