Abstract

Additive manufacturing can be understood as a general term to represent a range of technologies for building physical objects by adding material, layer by layer, from a virtual 3D model (ISO/ASTM, 2015). One of the main advantages of this technology is the flexibility to design the component with a view to reducing its mass in order to guarantee its mechanical properties (Gibson; Rosen; Stucker, 2015). As one of the most widely used techniques, laser powder bed fusion is characterized by the interaction of the raw material with the laser beam, thus resulting in a melting pool where rapid solidification will occur (Shin et al., 2018). One of the advantages of the Laser Powder Bed Fusion (L-PBF) technique over other additive manufacturing techniques is that it can not only work with different metal alloys, but also print parts with complex geometries (Gibson; Rosen; Stucker, 2015). In the context of this project, the introduction of a new alloy with Niobium (Nb) presents various challenges, ranging from microstructural defects to the resistance of components to various types of stress, for example machinability. In order to add to the overall development of the project, this scientific initiation aims to carry out the machining of samples from L-PBF processing, as well as to the ideal cutting parameters for the alloy developed.
