Title: ADDITIVE FABRICATION WITH INFILTRATABLE STRUCTURES
Abstract:
An infiltratable material forms a net shape containing a porous network that can be infiltrated with a supplemental material, commonly referred to as an infiltrant, e.g., by heating the infiltrant so that it melts and wicks into the porous network of the net shape. By using additive fabrication technologies to spatially dispose an infiltrant about an infiltratable structure, a composite structure can be created that advantageously controls the amount of infiltrant applied to the infiltratable structure and the spatial distribution of the infiltrant about and/or within the infiltratable structure prior to infiltratio
