Abstract

This Young Investigator Award project, which is aligned with FAPESP's funding initiatives focused on scientific and technological cooperation on advanced manufacturing topics, aims to conduct systematic studies of processing, monitoring and control in the additive manufacturing (AM) process using the powder bed fusion technique with laser beam (PBF-LB). The objectives include: i) the experimental design and computational simulation of the layer deposition process at a micrometric scale and the mechanical behavior of the product; ii) PBF-LB processing of materials with different degrees of absorbance using a high-power laser with programmable heat distribution shape and beam diameter; iii) the exploration of post-processing routes by heat treatment, and finally iv) the microstructural and the mechanical properties characterization of samples. The processability of materials that have distinct processability characteristics will be discussed, such as AISI-H13 (UNS T20813) and Maraging M300 (UNS K93120) steels and CuCrZr alloy (UNS C18150). At the end of the project, the expectation is that the knowledge base will be established for the definition of processing methodologies, post-processing, and characterization of different materials processed by AM PBF-LB.
