Abstract

The invention discloses a copper-doped inorganic nano-grade composite material used in 3D printing. The material comprises, by weight, 73-80% of ceramic precursor powder, 5-10% of a nano-grade powder reinforcement material, 2-5% of copper powder, 2-5% of a surfactant, 2-5% of an organic solvent, 1-4% of an inorganic binder, and 5-10% of a low-temperature curing agent, wherein the particle size of the nano-grade powder reinforcement material is 20-200nm. According to the invention, the surfactant is used for carrying out a de-aggregation treatment upon the nano-grade powder, such that the nano-grade powder has excellent dispersion property. When the nano-grade powder is added into the ceramic precursor powder, ceramic compactness and strength can be improved, and product toughness can be further improved. The inorganic mixed powder, inorganic binder and low-temperature curing agent cooperate with each other, such that low-temperature fast bonding is realized. The inorganic nano-grade composite material is used as a prototyping raw material for a 3D printing rapid prototyping machine. With the material, fast prototyping can be effectively realized on a 3D printer. The material can be applied in 3D printers with different models.
