Resumo

The new developments in the additive manufacturing (AM) process offer great potential to generate novel applications and to induce technological innovations with engineering materials. In this field, there are still many challenges to understand, configure and control this new production process, which, however, has great potential for use in several areas, such as biomedical applications. In the present work, metallographic and surface characterization results obtained previously were analyzed in order to describe the size of the molten pool under solidification as well as to generate a new parameter to describe the LPBF process. As a result, sensitivity of the proposed parameter was detected with the melting modes of the process.
