Cracking behaviour of rené 80-type superalloy during laser-based directed energy deposition [PDF]

Features of microstructure, mechanical properties, and cracking behaviour of the René 80-type superalloy manufactured by laser-based directed energy deposition (DED-LB) have been investigated. Different cracking behaviours were observed in two thin walls

A Support Interface Method for Easy Part Removal in Directed Energy Deposition [PDF]

, 2019
In traditional directed energy deposition (DED) processes, post-processing involving laser cutting or wire electrical discharge machining is necessary for removing printed parts from the substrate, which is time consuming and labor intensive.

Pore evolution mechanisms during directed energy deposition additive manufacturing [PDF]

Porosity in directed energy deposition (DED) deteriorates mechanical performances of components, limiting safety-critical applications. However, how pores arise and evolve in DED remains unclear. Here, we reveal pore evolution mechanisms during DED using

Fine-spot laser direct energy deposition of gradient thin-walled honeycomb structure and compression property analysis

Journal of Materials Research and Technology
Integrating gradient materials with honeycomb structures offers a promising solution for achieving both multi-functional and lightweight. However, conventional laser direct energy deposition (L-DED) with large spot sizes (2–5 mm) limits deposition ...
