Directed-Energy Deposition

2022
AbstractThis article focuses on the directed-energy deposition (DED) additive manufacturing (AM) technique of biomedical alloys. First, it provides an overview of the DED process. This is followed by a section describing the design and development of the multiphysics computational modeling of the layer-by-layer fusion-based DED process.

Directed Energy deposition

2020
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, 2021
Abstract 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, 2019
Abstract 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.

Directed Energy Deposition Processes

2015
Directed 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.

On the machinability of directed energy deposited Ti6Al4V

Additive Manufacturing, 2018
Current 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.
