Selective Laser Melting, known as SLM printing, is an additive manufacturing method specially developed for 3D printing of metal alloys. This process allows manufacturing parts with complex shapes from the successive printing of layers of material from a digital model. It is a technique increasingly used in fields such as power generation, aerospace, healthcare and the automotive transport sector.
In order to enhance its progress it is necessary to study its viability in different types of alloys. Thus, the selection of printing parameters is critical to obtain alloys with good densification and to avoid or favour precipitation of secondary phases.
This project proposes the study of the effect of additive printing parameters by SLM on new steels. A study of phase transformations and microstructural characterization will be carried out, paying special attention to the multi-scale complexity and the crystallographic hierarchy of complex bainitic and martensitic structures.
