Selective Laser Melting of Commercially Pure Silicon

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2022
Selective laser melting (SLM) or Laser-based powder bed fusion (LBPF) is gaining much attention for the fabrication of novel materials with complex shapes, improved functionalities, and properties. An attempt has been made to fabricate hard and brittle silicon via SLM in the absence of any cracks.

Effect of process parameters on the phase transformation behavior and tensile properties of NiTi shape memory alloys fabricated by selective laser melting

, 2020
In this work, we show that selective laser melting (SLM), apart from producing complex structures, can also act as a metallurgical method to modify the Ni/Ti ratio of NiTi shape memory alloys, and thus providing a feasible approach to tailor the ...

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.
