Direct laser sintering of a copper-based alloy for creating three-dimensional metal parts

A review on selective laser sintering/melting (SLS/SLM) of aluminium alloy powders: Processing, microstructure, and properties

“…However, in agreement with Tang et al [57]; Kruth et al [49] described SLM as sintering the metal powder directly by the high-energy laser beam to achieve 100% density in a single step as opposed to direct or indirect SLS. A study of various SLM literature shows that it requires careful process control in order to avoid difficulties such as part distortion, balling and dross 22 formation in the melt pool that cause poor surface quality [47].…”

A Review on Selective Laser Sintering: A Rapid Prototyping Technology

“…The description of various stages of data preparation and model building has been presented. Tang [7] presented a paper on "Direct laser sintering of copper based alloy for creating 3 Dimensional metal parts". He discussed the importance of direct laser sintering.…”

“…The power requirements will depend on the raw material, speed of scanning etc. R. M. Miranda used 8KW fibre laser to sinter titanium based alloy [7]. K. Murali used pulsed Nd-YAG laser to sinter Iron-Graphite powder mixture and tested the results [6].…”

Effect of mixing time on the bed density, and microstructure of selective laser sintered (sls) aluminium powders

“…The challenge of delivering new customised products more quickly to meet customer's demand in order to avoid delayed delivery has led to the emergence of the direct selective laser sintering process (SLS) or selective laser melting (SLM) [1][2][3][4] . SLS/SLM process was developed at the University of Texas in Austin in 1987.…”
