1. A method of generating a formulation of a photopolymer composite material for use in a 3D printing system, the method comprising:
combining an acrylate oligomer, in the range between about 20.0-60.0 w % of the formulation, a ultraviolet (UV) initiator, in the range between about 0.001-0.5 w % of the formulation, and a reinforcing filler, in the range between about 5.0-60.0 w % of the formulation, in a blender;
generating a resin premix by blending the acrylate oligomer, the UV initiator, and the reinforcing filler through operation of the blender for a first amount of time;
combining the resin premix with an inorganic hydrate in the blender, wherein the inorganic hydrate is borax decahydrate and is in the range between about 22.0 to 25.0 w % of the formulation; and
generating a photopolymer composite resin by blending the inorganic hydrate and the resin premix through operation of the blender for a second amount of time.
