Abstract

A method (100) to manufacture reticulated metal foam via a dual investment solid mold, includes pre-investing a precursor (20, 30) with a diluted pre-investment ceramic plaster to encapsulate the precursor (20, 30); and investing the encapsulated precursor (20, 30) with a ceramic plaster within a mold (200) of a varied cross-section. A varied cross-section mold (200) includes a mold thickness (212) adjacent to an outer periphery (214) of a pattern (216) at a top (208) of the varied cross-section mold (200) which is between 200-500% of a thickness (220) between the outer periphery (214) of the pattern (216) at a base (222) of the varied cross-section mold (200). A varied cross-section mold (200) includes a trapezoidal prism shape with a pour cone (210) in a top (208), the top (208) larger than the base (222).
