Additive manufacturing is an emerging manufacturing technology that enables production of patient spe-cific implants, today primarily out of titanium. For optimal functionality and proper integration betweenthe titanium implant and the body tissues surface properties, such as surface oxide thickness is of partic-ular importance, as it is primarily the surface of the material which interacts with the body. Hence, in thisstudy the surface oxidation behavior of titanium parts manufactured by Electron Beam Melting (EBM®)is investigated using the surface sensitive techniques ToF-SIMS and AES. Oxide thicknesses comparableto those found on conventionally machined surfaces are found by both analysis techniques. However, abuild height dependency is discovered for different locations of the EBM®manufactured parts due to thepresence of trapped moisture in the machine and temperature gradients in the build.
