所谓直接能量沉积3D打印-DED技术(Direct energy deposition),是指由激光在沉积区域产生熔池并高速移动,材料以粉末或丝状直接送入高温熔区,熔化后逐层积的一种激光直接能量沉积增材制造技术。该技术囊括激光、等离子、电子束几种不同的热源,材料包括粉末或丝状两种主要的形态。旗下技术类型可分为LENS激光工程网状透镜(La...
Directed energy deposition (DED) is a branch of additive manufacturing (AM) processes in which a feedstock material in the form of powder or wire is delivered to a substrate on which an energy source such as laser beam, electron beam, or plasma/electric arc is simultaneously focused, thus fo...

a multi-scale model that integrates a macro-scale transient three-dimensional mass and heat transfer model and a micro-scale thin-interface phase-field model is developed to simulate the solidification behavior of the molten pool and the dendritic growth behavior for direct energy deposition process....
Predicting the melt pool temperature distribution and history in direct energy deposition (DED) is crucial for estimating the microstructure, porosity, and mechanical properties of DED-fabricated metal parts. While analytical and numerical modeling methods have been introduced to predict the melt pool tem...

Umer Rashid, in Renewable and Alternative Energy Resources, 2022 8.10.16.4 Topography of terrestrial surface Large numbers of terrestrial surfaces of the earth are dominated by the low and flat to relatively high plains. These low plains are the sedimental deposition areas due to the low elevation...
