Thermo-mechanical Modelling of the Directed Energy Deposition (DED) Process for the Optimization of Deposition Strategies

2023
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, 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.

A Review on Using of Directed Energy Deposition (DED) in Manufacturing Processes

2020
Direct Energy Deposition (DED) is one of the laser-based additive manufacturing methods for the production offunctional metallic parts. DED process, which started with the use of the renovation processes of aerospace parts, hasbeen offering direct part production in the last decades. Numbers of experimental and theoretical studies have been donefor the
