Abstract: A method to manufacture reticulated metal foam via a dual investment solid mold, includes pre-investing a precursor with a diluted pre-investment ceramic plaster to encapsulate the precursor; and investing the encapsulated precursor with a ceramic plaster within an mold of a varied cross-section. A varied cross-section mold includes a mold thickness adjacent to an outer periphery of a pattern at a top of the varied cross-section mold is between 200-500% a thickness between the outer periphery of the pattern at a base of the varied cross-section mold. A varied cross-section mold includes a trapezoidal prism shape with a pour cone in a top, the top larger than the base.
