The performance of steel parts produced by additive manufacturing (AM) is still insufficient for some industrial applications, particularly in the fields of production and tooling, which require increased durability specifications. Their demand high hardness (HRC>60), while satisfying other mechanical constraints (fatigue, toughness), thermal, and chemical properties. The aim of the FACDUR project is to control and optimize the processability, from printing to post-treatments, of materials capable of meeting these requirements. It will rely on the complementary skills of the three partners involved (IPC, LabECAM, MATEIS) to assess the opportunities offered by two AM technologies, laser powder bed fusion and MIM-like, based on different consolidation principles: laser and assisted sintering. Tool steels, martensitic steels, and composite materials with metallic matrix are especially targeted.
The aim is to study the relationships between processes, microstructures, and properties to better understand the mechanisms and establish optimal printing, consolidation, and heat treatment parameters. This two-technology approach will allow evaluating several feasibility axes to achieve the desired objectives and performing a comparative study of the possibilities offered to adequately meet each industrial need. It will also highlight their complementarities, particularly in the selection of powders based on their morphological characteristics. The ultimate goal is to manufacture demonstrators for each of the technologies capable of highlighting these new opportunities in the targeted markets. Their economic and environmental impacts will be evaluated to offer a comprehensive view of the industrial challenges in the use of metallic AM technologies.
