Abstract

Selective electron beam melting (SEBM) is a powder bed–based additive
manufacturing (AM) technology and allows the fabrication of complex
metal components. However, the high building temperatures necessary for a
stable process prohibit the fabrication of small internal features and
intended cavities, e.g., for cooling purposes and heat exchangers. In
this work, a novel scan strategy is used to seal prefabricated notches
on the surface of Ti-6Al-4V substrates and to create microducts without
applying additional materials. Influencing factors are identified and a
process map for the SEBM sealing process is established. The impact of
the determined strategy on the material properties regarding surface
structure and composition is investigated. This sealing process can be
followed by conventional SEBM-based additive manufacturing to build
complex structures on the sealing layer due to its high flatness.
