A paper published in the October 2026 issue of Additive Manufacturing, titled 'Superlinear increase in productivity of laser powder bed fusion through synchronized multi-laser scanning,' proposes a synchronized multi-laser scanning strategy that breaks through the theoretical productivity ceiling of dual-laser laser powder bed fusion (LPBF) systems. Using a multi-laser system architecture with fully overlapping fields of view (multiple scanners fully covering the build plate), the study achieved simultaneous action of multiple laser beams on a single part: high-density multi-layer builds experimentally demonstrated a 2.32x increase in build rate (or an equivalent 16% gain in laser efficiency). The optimal beam spacing predicted by the thermal model was experimentally validated, and alignment and synchronization tolerances were quantified to ensure process robustness. Previously, multi-laser system operators typically assigned parts to individual lasers to avoid beam-to-beam interactions (vapor plume interference, melt pool cross-effects), which limited path optimization freedom. This study demonstrates that synchronized scanning can keep all lasers continuously engaged on the same part while ensuring density, offering a new pathway for increasing hourly output of large and small-batch LPBF parts. Value for powder buyers: (1) A multiplied LPBF build rate means metal powder consumption per unit of equipment capacity scales up accordingly; rising multi-laser equipment installations will drive demand for commonly used printing powders such as titanium alloys, aluminum alloys, and stainless steels. (2) Synchronized multi-laser operation places higher demands on powder batch consistency and recoating quality, making powders with high sphericity and low satellite content better suited for synchronized multi-laser conditions.
