A formulation for a photopolymer composite material for a 3D printing system includes an acrylate oligomer, an inorganic hydrate, a reinforcing filler, and an ultraviolet (UV) initiator. In the formulation the acrylate oligomer may be found in the range between about 20.0-60.0 w % of the formulation. The inorganic hydrate may be found in the range between about 20.0-50.0 w % of the formulation. The reinforcing filler may be found in the range between about 5.0-60.0 w % of the formulation, and the UV initiator may be found in the range between about 0.001-0.5 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 oligomer, an inorganic hydrate, a reinforcing filler, and an ultraviolet (UV) initiator.

3D printed material, structure and method for making the same

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.

3D printing of a composite material via sequential dual-curing polymerization

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.

Dual-mediated polymerizable composite for additive manufacturing

The present invention relates to polymer compositions suitable for 3D printing. The composition comprises 60 to 80 mass % of oligoester acrylate; 10 to 30 mass % of a liquid polyethylene glycol; 7 to 9 mass % of a non-liquid polyethylene glycol; and 0.1 to 1 mass % of a system of photopolymerization initiators. A distinguishing feature of the composition is that after being extruded at an environment temperature of 22&#xb0; C. with the extrusion rate of 2.5 to 3.5 cm/sec through a nozzle of a hand-held 3D printing device having an output orifice with a diameter in the range of 0.6 to 1.5 mm and after being irradiated after extrusion with a light having a wavelength in the range of 390 to 410 nm by LEDs having a total power of 2 Wt, the composition maintained its shape without a support.
