摘要: Biological materials (e.g. wood, trabecular bone, marine skeletons) rely heavily on the use of cellular architecture, which provides several advantages: (1) The resulting structures can bear endurable mechanical loads using a minimum given bulk material, thus enabling lightweight design principles. (2) inside is accessible to body fluids deliver required nutrients. (3) Furthermore architectures grow organically by adding or removing individual struts changing shape constituting elements. All these facts make reasonable choice for nature. Using Additive Manufacturing Technologies (AMT) it now possible fabricate such applications in engineering and biomedicine. In this book chapter we present methods allow 3D-analysis properties with open porosity. Various different are studied. order quantify influence apparent density always kept constant. lithography based AMT described compared regarding their suitability fabrication structures.
