Abstract

Cellular materials offer high strength accompanied by low-density and can offer high stiffness, good impact-absorption, and thermal and acoustic insulation. In this paper, the authors describe their progress towards exploring the use of metal casting into 3D printed sand molds for creating cellular materials and sandwich panels. The use of 3D printing allows for the fabrication of sand molds without the need for a pattern, and thus enables the creation of cellular structures with designed mesostructure from a bevy of metal alloys. The quality-of-fill results for several cast aluminum cellular parts of varying geometry are presented in this paper, along with a discussion of overall truss diameter variation.
