摘要

Low-density cellular materials, metallic bodies with gaseous voids, are a unique classification of material that have high strength, good energy absorption characteristics, good thermal and acoustic insulation properties, accompanied by an extremely low mass. Unfortunately, current cellular material manufacturing processes severely limit a designer's ability to control the part mesostructure, the material composition, and the part macrostructure. In this paper, the capability of existing commercially available Additive Manufacturing technologies to manufacture cellular materials is evaluated using the Preliminary Selection Decision Support Problem. Through this evaluation, the technologies that are most suitable for this class of materials are chosen. More importantly, the general material processing issues of these technologies are identified. Promising technical directions are also posed as a means of addressing the limitations of the currently available processing techniques.
