During part fabrication by laser powder-bed fusion ( L-PBF ) , an Additive Manufacturing process , a large amount of energy is input from the laser into the melt pool , causing generation of spatter and condensate , both of which have the potential to settle in the surrounding powder-bed compromising its reusability .
 manufacturing process: fabrication; enabling technology: laser; concept or principle: fusion; manufacturing process: L-PBF; manufacturing process: Additive Manufacturing process; enabling technology: laser; material: melt pool; process characterization: spatter
