Abstract

Disclosed is a 3D printing manufacturing technology of a metal porous material with a through hole structure. The 3D printing manufacturing technology of the metal porous material with the through hole structure comprises the following steps that S1, a 3D model of the porous material with the actual structure and the actual size is drawn; S2, 3D printing of a porous material blank is conducted; S3, thermosetting treatment of the porous material blank is conducted; S4, powder in the porous material blank is removed to form inner channels and pores; and S5, a required porous material product is manufactured through degreasing and sintering. The 3D printing manufacturing technology of the metal porous material with the through hole structure omits laser devices, has the advantages of being simple in manufacturing technology and low in manufacturing cost, can manufacture the structure with complex inner pore channels on the basis of a low-cost 3D printing technology, can be widely applied to manufacture of two porous materials including honeycomb-shaped metal porous materials and open-pore foam materials, and is broad in application prospect.

Description

technical field [0001] The invention relates to a class of porous materials with complex internal structures and the field of 3D printing manufacturing technology thereof, in particular to a 3D printing manufacturing technology of metal porous materials with through-hole structure. Background technique [0002] Typical porous materials include honeycomb porous materials, open-cell foam materials and closed-cell foam materials, among which the first two are porous materials with a through-pore structure. Metal porous materials have both functional and structural properties. As a structural material, it has the characteristics of light weight and high specific strength. As a functional material, it has the advantages of energy absorption and shock absorption, noise reduction, electromagnetic shielding, breathable and water permeable, and heat insulation. Heat transfer and other aspects show their own characteristics, so metal porous materials have been more and more widely use...
