Abstract

The invention discloses a 3D printing method of a metal ceramic functional gradient part in an alternating magnetic field. A metal material with excellent electric conductivity in the alternating magnetic field generates induction current inside due to continuous change of a magnetic field; based on different responses of the metal material with excellent electric conductivity and ceramic not easy to conducting electricity to the alternating magnetic field, the directional distribution of the metal materials is controlled through the alternating magnetic field in the printing process; the magnitude of driving force is changed through changing alternating current intensity and current frequency; the metal ceramic functional gradient part is prepared; the 3D printing of the metal ceramic gradient part in the alternating magnetic field is realized; the gradient material distribution can be realized in any space position; the material and the equipment cost are saved; and the 3D printing method is suitable for wide popularization and application.

Description

technical field [0001] The invention belongs to the 3D printing technology in the field of mechanical manufacturing, and in particular relates to a 3D printing method for metal-ceramic functional gradient parts in an alternating magnetic field. Background technique [0002] 3D printing is a rapid prototyping technology that uses digital models as the driving source to construct the spatial form of objects by layer-by-layer printing. In recent years, with the development of additive manufacturing to functional parts manufacturing, metal additive manufacturing has also reached an extreme. With the development of the earth, the existing metal 3D printing technologies include selective laser sintering technology (SLS), selective laser melting technology (SLM), laser rapid prototyping technology (LRF) or laser stereoforming technology (LSF). Most of the laser operations remain in the homogeneous processing of single materials, and it is impossible to realize the forming of parts ...
