Effect of layer thickness setting on deposition characteristics in direct energy deposition (DED) process

Optics & Laser Technology, 2016
Abstract Direct energy deposition is an additive manufacturing technique that involves the melting of metal powder with a high-powered laser beam and is used to build a variety of components. In laser-assisted metal deposition, the mechanical and metallurgical properties achieved are influenced by many factors.

Vision-based inspection system for cladding height measurement in Direct Energy Deposition (DED)

Additive Manufacturing, 2019
Abstract A vision-based inspection system based on three digital cameras is proposed for measuring the cladding height in the Direct Energy Deposition (DED) process. To improve the accuracy of the cladding height measurements, an image processing technique is applied to remove the undesirable zone from the binary image.
