The effect of productive and quality deposition strategies on residual stress for Directed Energy Deposition (DED) process [PDF]

Manufacturing Letters
In the Directed Energy Deposition (DED) realm, challenges persist concerning process stability and mechanical properties in as-built components. Facts like inconsistent laser head feed rate and accumulated heat during multi-layer deposition result in variations in melt pool energy, causing variant clad widths and heights. Moreover, significant residual

Development and evaluation of a dynamic powder splitting system for the directed energy deposition (DED) process [PDF]

CIRP Annals, 2020
Abstract A dynamic powder splitting system (DPSS) was developed to overcome a slow powder flow rate (PFR) response in conventional powder delivery systems used in the Directed Energy Deposition (DED) additive manufacturing process. Complementary to the main powder delivery system, the DPSS uses a custom valve to split powder flow and cyclone ...
