The importance of additive manufacturing increased significantly over the last decades. From a materials science point of view a broad field of research and development arises which deals with many engineering fields to exploit the full potential of this innovative type of production. This master thesis deals with an extensive characterization of titanium based additive manufactured components and the powder in use. The research started at the begin of the production chain, with the characterization of the powder benchmarking different processing routs and ended with the investigation of the heat-treated additive manufactured samples. It was found that the chemical composition of the powder significantly influences the mechanical properties of the additive manufactured samples due to the amount of solute strengthening elements. It is also shown that impurities and nonspherical particles on the powder surface leads to pores and connecting faults. Furthermore, the roughness of the as-built samples is given by the powder size distribution of the atomization process. Another section of this thesis deals with the literature research of titanium alloys tailored for additive manufacturing to prevent occurring problems caused due to the manufacturing process, e.g. solidification texture.
