The ongoing globalization and industrialization requires a more and more sustainable usage of the available resources and processes. An increasing interest in new manufacturing methods, such as laser powder bed fusion (LPBF), for flexible production of high complex components can be observed. LPBF is one of many Additive Manufacturing techniques which allow the production of high complex components directly from 3D-CAD models. Component properties can be tailored by means of the three factors LPBF process parameters, material chemistry, and geometrical design. This chapter examines and evaluates the potentials of the LPBF process regarding the production of tailored components experimentally. Increasing preheating temperature during the manufacturing process led to lower cooling rates and therefore larger grain sizes. The chapter also examines the lattice structures to demonstrate the potential improvement of component capabilities due to use of special component geometries.
