The conventional production based on subtractive machining produced a huge amounts of material scraps. This is economically and environmentally unsustainable for the companies which nowadays are looking for alternatives to conventional machining processes, such as Additive Manufacturing technologies. This work is an experimental work that aims to analyze the Assessment of the machinability of additively manufactured steels achieving the following goals : • Comparison of AM and conventional materials: the purpose is to verify the existence in literature a specific experiment that shows the better machining settings to work the additive manufactured Stainless steel AISI 304, but during the investigation, it has been realized that in the literature there isn’t a similar experiment with a direct comparison about machinability AM AISI 304 and the conventional one.
