Abstract

A method for fabrication of a 3D printed part with high through-plane thermal conductivity is provided, where pure polymer particles and a carbon-based filler for heat conduction are subjected to milling and mixing in the mechanochemical reactor disclosed in Chinese patent ZL 95111258.9 under the controlled milling conditions including milling pan surface temperature, milling pan pressure, and number of milling cycles; then a resulting mixture is extruded to obtain 3D printing filaments; and finally, the 3D printing filaments are used to fabricate the 3D printed part with high through-plane thermal conductivity through fused deposition modeling (FDM) 3D printing. The fabrication method can realize the fabrication of a 3D printed part with high through-plane thermal conductivity through the FDM 3D printing technology, features simple process, continuous production, etc., and is suitable for the industrial production of thermally-conductive parts with complex structures.
