Abstract

Additive manufacturing delivers a high degree of manufacturing freedom. New applications such as structural integration of cellular structures are enabled by this technology. However, the manufacturing process bears some challenges, that need to be investigated. This contribution focusses on manufacturing, elastic properties and lightweight degree assessment of two dimensional cellular solids. To get a high lightweight degree at a given stiffness one must be aware of the structure's geometry and the amount of material used in a representative volume element. Even though this can be obtained by simple geometric considerations little research has been conducted on that aspect.

In this work we deliver exact solutions for the so called relative density, which denotes the volume fraction of material used in a representative volume element, which is crucial to assess the lightweight degree. Furthermore an approach in order to realize the corresponding structures by a powder bed based additive manufacturing process will be presented.
