Abstract: Porous metal material is a new kind of multifunctional materialwith low density and a lot of superior performances. Aiming at manufacturing process of porous metal materials, this paper introduces some common methods at home and abroad. A kind of regular cellular metal based on cubic structure is proposed, and the cubic cells are manufactured through sheet metal stamping process. Then the cells would be bonded together by laser welding to form one layer. Secondly the respective layers could be bonded together by adhesive or braze-welding to form the block we need. Finally some experiments are carried out to validate the feasibility of this progress, and the improvement and the future work are given.
