| Abstract Scope |
Laser directed energy deposition (L-DED) is an important category of metal additive manufacturing (AM) technologies that offers unique advantages such as printing large-scale parts, adding surface coatings at a fast speed, and fabricating functionally-graded materials and multi-material components. However, printing certain geometries such as overhang structures has been a challenge with this technology. An L-DED system that uses a co-axial conical powder-feeding nozzle was employed in this study to explore its capabilities in building challenging structures using nickel-based superalloys. Some practical solutions were developed to expand the flexibility of the L-DED technology in building complex shapes. |
