Low-temperature 3D printing material and preparation method thereof

The invention discloses a low-temperature 3D printing material and a preparation method thereof. The low-temperature 3D printing material is prepared from, by mass, 58-84.2% of PCL, 15-40% of surface-processed inorganic powder, 0.3-1% of an antioxidant and 0.2-1% of a lubricating agent. The sum of the mass percentage content of all the components in the low-temperature 3D printing material is 100%. The conveying problem of the PCL material is solved, the low-temperature performance of the PCL material can also be kept, and the application field of the PCL material in the 3D printing industry is widened.
