This abstract first appeared for US patent application 20250121435 titled 'ENERGY BEAM EXPOSURES IN POWDER BED FUSION
Original Abstract Submitted
a powder bed fusion additive manufacturing method including exposing layers of a powder bed to an energy beam to selectively melt areas of each layer, at least a proportion of the areas are melted using a pulsed exposure. the method may further include commanding an energy beam source to produce at least one pulse of the pulsed exposure having a pulse duration of less than 200 microseconds. the step of commanding may include specifying a plurality of raised power levels above a base power level for the powder waveform of the at least one pulse.
