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.

Aspects of the disclosure are directed to additively manufacturing a three-dimensional structure. As may be implemented in accordance with one or more embodiments, a plurality of stacked layers are deposited, and for one or more respective layers of the plurality of stacked layers, pores are formed within the layer by applying pulsed energy to the layer. The pulsed energy is used to create a space sealed within the layer and having an inner surface defined by material of the layer.

A method for producing an additively manufactured, graded composite transition joint (AM-GCTJ) includes preparing a grating or lattice pattern from a first alloy A; the grating or lattice pattern includes pores in the grating or lattice patterns. The grating pattern is built from a first end to a second end being denser on the first end than on second end, and gradually reduces density by increasing the pore size and/or reducing density of the grating or lattice pattern; adding a second alloy B powder to the second end of grating or lattice pattern. The second alloy B powder is filled towards the first end. A composite is formed of first alloy A and second alloy B powder in the AM-GCTJ. The composite is subjected to hot isotropic pressing (HIP) to densify the composite. The second alloy B is graduated from the first end to the second end O of AM-GCTJ.
