Abstract
A method of forming a build in a powder bed includes emitting a plurality of laser beams from selected vertical-cavity surface emitting lasers (VCSELs) of at least one VCSEL array onto the powder bed, the selected VCSELs of the at least one VCSEL array corresponding to a pattern of a layer of the build; and simultaneously melting powder in the powder bed corresponding to the pattern of the layer of the build.
