Most of the authors publishing papers on high-entropy alloys (HEAs) and compositional complex alloys (CCAs) produced their material by the melting & casting route. In our talk we would like to introduce the advantages modern additive manufacturing (AM) methods offer for the fabrication of these new type of metallic materials. We claim that AM has an enormous potential for the processing of HEAs at an industrial scale since it allows an effective experimental alloy screening, the direct fabrication of compositionally complex and crack-sensitive materials, flexible compositions and gradient structures while following an economical usage of material. To demonstrate this potential our contribution focuses on the following examples:

I) High-throughput experimental screening in the Al-Ti-CoCrFeNi material system utilizing in-situ alloying by means of laser cladding.

II) Crack free processing of refractory type HEAs (RHEAs) by laser powder and wire direct energy deposition (DED)

III) Fabrication of different transition metal HEAs by laser powder bed fusion and fused filament fabrication.

Our presentation will conclude with an outlook on future developments and challenges in the field of AM of HEAs and CCAs from both a scientific and application-oriented perspective.
