Abstract
A method of printing a 3D printing a photopolymer composite material includes providing a resin premix material including an acrylate monomer or an acrylate oligomer, an inorganic hydrate, a reinforcing filler, a co-initiator, and an ultraviolet (UV) initiator. A thermal initiator is mixed with the resin premix to form a photopolymer composite resin. The photopolymer composite resin is repeatedly extruded and dual-cured by a 3D printing system to create a photopolymer composite material. The 3D printing system includes a control system, a mixing system, a feeding system in fluid communication with the mixing system, a light curing module controlled by the control system, and a printing head controlled by the control system.
