Dual-mediated polymerizable composite for additive manufacturing

A method of generating a formulation of a photopolymer composite material for use in a 3D printing system, the method comprising:

• at least one of an acrylate monomer and an acrylate oligomer in the range between about 10.0-30.0 w % of the formulation, an ultraviolet (UV) initiator, in the range between about 0.001-0.2 w % of the formulation, a co-initiator in the range between about 0.001-0.05 w % of the formulation, an inorganic hydrate, comprising a borax decahydrate, in the range between about 22.0-30.0 w % of the formulation, and a reinforcing filler, in the range between about 50.0-80.0 w % of the formulation, in a blender;
• generating a resin premix by blending the acrylate oligomer, the UV initiator, the inorganic hydrate, the co-initiator, and the reinforcing filler through operation of the blender for a first amount of time;
• combining the resin premix with a thermal initiator in the range between about 0.001-0.05 w % of the formulation in the blender;
• and
• generating a photopolymer composite resin by blending the thermal initiator and the resin premix through operation of the blender for a second amount of time.
