Laser Additive Manufacturing for the Realization of New Material Concepts

Pfleging, Wilhelm ORCID iD icon; Santos Solheid, Juliana dos


In additive manufacturing processes, components are built up in layers from liquids, powders, wires or foils using chemical or physical processes. Direct energy deposition (DED) or powder bed fusion (PBF) can be used as additive manufacturing processes in which metal powder or wires are used to print dense metal layers on substrates or on freeform surfaces of existing components [1]. Metal powder (pure elements, element mixtures, master alloys) or metal wires are melted at high speed and instantaneously deposited in layers on respective metallic substrates. In case of the so-called laser cladding [2], this technology is generally used for applying coatings or for tool repairs. Compared to subtractive processes, additive processes save time and resources, as the material is only added where it is needed. Established steels, nickel-based alloys or titanium alloys are typically used. However, it is also possible to obtain completely new materials by in-situ alloying of powder mixtures or to create material gradients by changing the powder mixture composition during the build-up [3]. High entropy alloys (HEAs) represent a new research field for future applications. ... mehr
