Characterization of Ti–6Al–4V Fabricated by Multilayer Laser Powder‐Based Directed Energy Deposition

Laser powder-based directed energy deposition (DED-L) is increasingly being used in additive manufacturing (AM). As AM technology, DED-L must consider specific challenges. It achieve uniform volume growth over hundreds of layers and avoid heat buildup the deposited material. Herein, Ti–6Al–4V fabricated using an approach that addresses these challenges relevant terms transferability to DED–L applications AM. The assessment obtained properties discussion their relationship process conditions resulting microstructure are presented. quality proven reproducibility between individual blanks with respect building height. characterization demonstrates excellent mechanical achieved at room temperature 400 °C.
