Abstract

A method for the additive manufacturing of a closed-cell porous matrix is described herein. A powder-bed, additive manufacturing process is used to create a piece with partially-closed cavities filled with unfused powder. Vacuum, negative pressure, positive pressure, or solvent is used to evacuate the powder from the cavities. Finally, a fresh layer of powder is used to cover the opening of the cavity and the powder is fused on top to close the opening.
