Abstract
(EN)
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 co­initiator, 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.
