Directed Energy Deposition (DED) is a method for melting material as it is being deposited layer-by-layer. Material in wire or powder form is delivered along with the energy required to melt it. Although it has been shown that a number of material types can be processed this way, DED is almost exclusively applied to metals in both research and ...

Magnetically assisted directed energy deposition
Journal of Materials Processing Technology, 2021Abstract Poor powder catchment efficiency, is a limiting factor in the adoption of Directed Energy Deposition for the processing of expensive materials, complex shapes and for the sake of energy efficiency. This study demonstrates a novel approach to improve powder catchment efficiency using a magnetic field to direct ferritic steel powder during ...

Directed energy deposition of molybdenum
International Journal of Refractory Metals and Hard Materials, 2019Abstract Two directed energy deposition processes were evaluated for additive manufacturing of molybdenum. First, a laser-based process was used to deposit plasma spheroidized molybdenum powder. The effects of laser power, substrate temperature, and substrate composition on deposition quality were explored.

On the machinability of directed energy deposited Ti6Al4V
Additive Manufacturing, 2018Current class Directed Energy Deposition (DED) techniques used for component manufacture and repair have inherently poor geometrical tolerance. Hence, there remains a requirement to apply conventional machining strategies post build in order to achieve finished components.

Directed Energy Deposition Processes
2015Directed energy deposition (DED) processes enable the creation of parts by melting material as it is being deposited. Although this basic approach can work for polymers, ceramics, and metal matrix composites, it is predominantly used for metal powders. Thus, this technology is often referred to as “metal deposition” technology.

Direct processes in the energy deposition of protons in silicon
IEEE Transactions on Nuclear Science, 1996The low energy part of proton induced SBD spectra have higher number of counts than expected from p+Si reactions. This is the case for all proton incident angles but the effect increases when approaching grazing angles. The effect is shown to be mainly due to direct ionization (including straggling) by the protons.
