Research progress of 3D printing of bionic damping materials
Compared with the traditional material manufacturing technology,the bottom-up additive manufacturing process of 3D printing technology has a high degree of similarity with the formation process of biological structures,which can more effectively mimic the complex structure and functionality of biomaterials.However,there are still some problems in technology and materials.And there is a lack of systematic research review.Based on different 3D printing technologies applied to the preparation of biomimetic damping materials,the technical characteristics of 3D printing technologies such as light curing technology,material extrusion technology,material jetting technology and powder bed fusion technology are reviewed.This paper summarises the development tendency of the 3D printing technology towards the microscopic scale.In this paper,the performance of pore structure,shell-like soft-hard phase stack sandwich structure,honeycomb-like lightweight porous structure,carapace-like spiral sandwich structure,horn-hoof hollow tube layered structure and other biomimetic damping materials are analyzed.The technical points and problems to be solved in the printing process of different printing technologies in the bionic damping materials are analyzed.The development trend of the 3D printing technology of the bionic damping materials is discussed from the aspects of new materials,new design,new means and new ways,so as to provide references for the rapid advancement of the technology.
