SEBM is a rapid prototyping/manufacturing technique allowing for the direct translation of CAD models to real world objects. Using SEBM we are able to produce structures of arbitrary geometry in a well-defined manner. Here, we introduce a self-designed 3D-auxetic structure and determine its mechanical properties. We also address the dependence of Young's modulus on relative density. References 1 R. Lakes, Science 235, 1038 (1987). 2 Y. Wang and R. Lakes, Solids Struct. 39, 4825 (2002). 3 P. Pastorino, F.
