Abstract

The invention relates to an anti-friction material based on FDM 3D printing, a preparation method of the anti-friction material and a method for enhancing an anti-friction property of the product made of the material. The anti-friction material based on FDM 3D printing is a material which is mainly made of babbitt metal powder and thermoplastic resin. The preparation method comprises the following steps: (1) mixing various components in a composition, and preferably fully mixing the components for 5-30 minutes by a high-speed mixer; and (2) carrying out melt plastification on a mixture obtained by mixing in the step (1) through a double-screw extruder, and carrying out granulation through a granulator. The method for enhancing the anti-friction property of the product made of the anti-friction material based on FDM 3D printing comprises the following steps: (1) preparing the anti-friction material based on FDM 3D printing into a 3D printing product; and (2) placing the 3D printing product obtained in the step (1) into an electromagnetic induction heating furnace, and melting babbitt metal so that a gap in the product is filled with the melted babbitt metal. The anti-friction material for FDM 3D printing has anti-friction characteristic.

Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to an FDM 3D printing-based antifriction material, a preparation method thereof, and a method for enhancing the antifriction performance of the material product.
