This work aims to compare the two state of the art Powder Bed Fusion Technologies, mainly from the mechanical properties point of view. For making a good comparison of the two technologies five stages have been followed in this thesis. In the first stage, an adequate standard for the tensile test, and the specimen used had to be chosen. This stage is very important because the chosen standard can affect the values of some of the results, and by considering a standard which is not used by the other institutes or laboratories, the value of the work and results will decrease, since they cannot be compared to the results of the other works related to these technologies.
