Abstract

The invention discloses a chromium-doped inorganic nanocomposite material for 3D printing. The chromium-doped inorganic nanocomposite material comprises the following components in percentage by weight: 73-80% of ceramic precursor powder, 5-10% of nano-powder reinforcing material, 2-5% of chromium 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-powder reinforcing material is 20-200nm. By adopting the surfactant to perform deaggregation treatment on nano-powder, the nano-powder has excellent dispersivity; by adding the nano-powder into the ceramic precursor powder, the density and strength of ceramic can be improved, and the toughness of a product can be further upgraded; by mutually coordinating and matching the inorganic mixed powder, the inorganic binder and the low-temperature curing agent, the fast binding can be realized at low temperature; and the inorganic nanocomposite material can be used as a molding raw material of a 3D printing fast molding machine, the fast molding on the 3D printing machine can be effectively realized, and the chromium-doped inorganic nanocomposite material can be applied to a variety of types of 3D printing machines.
