Selective Laser Melting of Commercially Pure Silicon
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2022Selective 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.

Selective Laser Melting of Copper
Materials Science Forum, 2016In 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, 2023Commercially 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, 2020Abstract 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.

Selective Laser Melting in Dentistry
2010Although casting is currently the first choice to produce metallic frame work selective laser melting (SLM) has established. Based on a CAD/CAM system the digital data of the frame work are transferred to the production machine. The three dimensional data set of the transferred in to numerous quasi 2-dimensional data. Each of these data sets represents

Selective Laser Melting of Ti42Nb Composite Powder and the Effect of Laser Re-Melting
Key Engineering Materials, 2019Ti-Nb based alloys have the potential to be used as structural implant materials due to their excellent bio-compatibility and ability to reduce stress shielding. The idea to additively manufacture Ti-Nb based alloys using selective laser melting (SLM) technology can further improve the resultant implant quality.

Process optimization in selective laser melting
2004The work presented here summarises part of the work I have done for the past six years. After a few interesting months of research on laser cutting of thick steel plates, I was lucky to land up in the emerging domain of Rapid Prototyping (RP): producing complex products layer by layer, directly from 3D CAD information.
