A comparative study of continuous-wave versus pulsed-wave laser emission in direct laser metal deposition of SS316L thin walls [PDF]
Scientific ReportsDirect Laser Metal Deposition (DLMD), as a Directed Energy Deposition (DED) technique, can operate either continuous-wave (CW) or pulsed-wave (PW) laser emission, resulting in distinctly different thermal histories during material deposition.

Using a Trial Sample on Stainless Steel 316L in a Direct Laser Deposition Process
Metals, 2021 Direct laser deposition technology is used for the manufacture of large-size products with complex geometries. As a rule, trial samples with small dimensions are made to determine the deposition parameters. In order for the resulting products to have the

Building Multi-Material components by Direct Laser Deposition [PDF]
MATEC Web of Conferences, 2019 Most mechanical components are usually made of a single material, as a compromise between chemical, physical and functional properties. When designing an object, the choice of one material over another is driven by many reasons.
