The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

The barriers to the progression of additive manufacture: perspectives from UK industry (2018, background): “The development of titanium within the aerospace industry is a prime example, for which there is also a large body of academic literature to support (Akerfeldt et al., 2016; Promoppatum et al., 2017; Qiu et al., 2015b).”
A Survey of Modeling of Lattice Structures Fabricated by Additive Manufacturing (2017, background): “…and transverse direction was 11% and 14% respectively due to the columnar prior-β grain morphology and the grain boundary α. Akerfeldt et al. [123] also found that the microstructural constituents have influence on the anisotropic elongation rate of the Ti6Al4V specimen fabricated by laser…”
On the origin of microstructural banding in Ti-6Al4V wire-arc based high deposition rate additive manufacturing (2019, background): “Two separate deposition-related microstructure banding features have been identified in the Ti64 WAAM samples that are characteristic of AM processing: namely HAZ bands, which have been well documented [8,11,20,31e34], and less reported solute segregation bands.”
