Abstract: A method of manufacturing a gas permeable metal is provided. First a plurality of metal powder particles is spread out tightly to form a first deposited layer and a second deposited layer is formed over the first deposited layer. Then scan the first and the second deposited layers along a plurality of parallel and spaced linear paths. A gap is formed by a difference between a width of melt pool and a linear distance between the two adjacent linear paths. The linear paths of the first and the second deposited layers are arranged with an angle therebetween. The gaps of the first and the second deposited layers are crossed over to form pores distributed like a grid graph. A plurality of the first and the second deposited layers are stacked and the pores are aligned to form continuous pore channels. Thereby the metal with good venting is produced conveniently.
