Abstract

Metal foams offer an exciting alternative to traditional materials. They have tailorable thermal properties, good energy absorption, and low density while retaining a significant portion of their bulk strength. The biggest difficulty in using metal foams is their random nature, which makes them unsuitable for structural applications. Cellular solids are ordered metal foams with predictable and repeating cellular patterns, making them easier to characterize than random foams. The manufacturing of cellular solids has proven to be expensive, time consuming, and difficult. Metal 3D printing is a process that fabricates metal structures layer-by-layer and is a promising alternative for cellular solid manufacturing. A downside of metal additive manufacturing is its susceptibility to processing defects, which hinder the performance of fabricated materials. This work uses X-ray computed tomography to map the deformation and defects present in a metal 3D printed cellular solid during compression loading. Results indicate that greater amounts of process defects tend to create more localized deformation.
