Characterization of Ti-48al-2cr-2nb Built by Selective Laser Melting

Social Science Research Network, 2021
Selective laser melting was applied to TiAl4822. Electron beam melting has been a major additive manufacturing process for TiAl4822, but ductility is a technical challenge with EBM. This research investigates the microstructure and the tensile properties

Melt Pool and Single Track Formation in Selective Laser Sintering/Selective Laser Melting

Advanced Materials Research, 2014
Selective Laser Sintering/Selective Laser Melting (SLS/SLM) is one of Additive Manufacturing (AM) processes that utilize layer by layer powder deposition technique and successive laser beam irradiation based on Computer Aided Design (CAD) data. During laser irradiation on metal powders, melt pool was formed, which then solidified to consolidated ...

Nutzung von Selective Laser Melting

Zeitschrift für wirtschaftlichen Fabrikbetrieb, 2019
Kurzfassung Besonders im Bereich der Luft- und Raumfahrttechnik ist in den letzten Jahren ein starker Anstieg der Relevanz der additiven Fertigung (Additive Manufacturing – AM) in verschiedenen Material- und Prozessvarianten verspürbar. Dabei liegt der Fokus vor allem auf den Möglichkeiten zur Erzeugung metallischer, additiv gefertigter ...

Selective Laser Melting

Laser Technik Journal, 2008
AbstractMithilfe der Strahlschmelztechnologie lassen sich räumliche Strukturen Schicht für Schicht aus einem pulverförmigen metallischen Ausgangsstoff herstellen. Dabei wird die Energie eines Strahls vom Pulver absorbiert und führt zu einem lokal begrenztem Verschmelzen von Partikeln.

Selective Laser Melting of Copper

Materials Science Forum, 2016
In this work the selective laser melting (SLM) of pure copper powder was studied. Because of low laser radiation absorption and high thermal conductivity it is very difficult to organize stable SLM process for copper. Five 10x10x5 mm specimens were fabricated by using different process parameters (scanning speed, point distance, exposure time, scanning

Selective Laser Melting of Commercially Pure Molybdenum by Laser Rescanning

3D Printing and Additive Manufacturing, 2023
Commercially pure (cp) molybdenum (Mo) is one of the high-temperature materials of immense potential. It has a body-centered cubic (bcc) structure so it is hard to fabricate using nonequilibrium processes such as the selective laser melting (SLM) without the formation of cracks due to its inherent brittleness.

Surface morphology evolution with laser surface re-melting in selective laser melting

Optik, 2020
Abstract Laser surface re-melting (LSR) is a promising method for improving the surface quality of parts fabricated via selective laser melting (SLM). In this research, LSR under different linear energy densities (LEDs) was conducted numerically and experimentally.

High density selective laser melting of Waspaloy®

Journal of Materials Processing Technology, 2008
In this work, high density Waspaloy® specimens were produced using specially assembled laboratory equipment by Selective Laser Melting (SLM). SLM of Waspaloy® powder was performed using a high power pulsed Nd:YAG laser. The laser parameters pulse energy (J), pulse width (ms), repetition rate (Hz) and scan speed (mm/min) were varied.
