Both selective laser sintering (SLS) and selective laser melting (SLM) are laser powder bed fusion. This chapter provides working of SLS and SLM and the role of their various parameters. Fabrication speeds due to these processes are low which is one of the drawbacks of additive manufacturing; this chapter provides various methods to increase the speed.

Denudation of metal powder layers in laser powder bed fusion processes
Acta Materialia, 2016 AbstractUnderstanding laser interaction with metal powder beds is critical in predicting optimum processing regimes in laser powder bed fusion additive manufacturing of metals. In this work, we study the denudation of metal powders that is observed near the laser scan path as a function of laser parameters and ambient gas pressure.

Melting modes in laser powder bed fusion
Materialia, 2019Depending on processing conditions, laser powder bed fusion (LPBF) is known to have two operational regimes - conduction mode and keyhole mode. Heat conduction is the dominant heat transfer mechanism for conduction mode, whereas heat convection is the dominant heat transfer mechanism for keyhole mode.

Comparison the Preparation Methods of Powder Feedstock for Laser Powder Bed Fusion
Solid State Phenomena, 2022Four various methods of powder feedstock preparation for laser powder bed fusion are compared. Application of commercial spherical powder leads to the formation of single-phased state. Powder mechanically alloyed during 14 minutes in air atmosphere provides conditions for the formation of double-phased state with nonuniform distribution of components ...
