For large frame metal additive manufacturing systems (build area >400×400mm) there are significant advantages to utilizing multiple lasers to produce parts, but primarily the addition of lasers means faster build rates, higher throughput and ultimately lower part cost. However, integrating additional lasers in a laser powder bed fusion (LPBF) process does not come without technical challenges, since the incorrect assignment and sequencing of these lasers can lead to material quality issues due to condensate and spatter interference.
