Directed Energy Distribution (DED) process involves a continuous and subsequent deposition of layers, by means of a laser heat source that melts the feedstock material supplied in form of powders or wires. Laser power, pow- der flow rate, travel speed affect temperature gradient distribution and residual stresses in components.

Vision-based inspection system for cladding height measurement in Direct Energy Deposition (DED)
Additive Manufacturing, 2019Abstract 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.
