Abstract

An additive manufacturing system includes a first laser device configured to generate a first laser beam and a second laser device configured to generate a second laser beam. The laser scanning devices include a first laser scanning device and a second laser scanning device. The first laser scanning device is configured to selectively direct the first laser beam from the first laser devices across a powder bed along a plurality of first hatching paths and a first contour path along a contour of the solid component. The second laser scanning device is configured to selectively direct the second laser beam from the second laser devices across the powder bed along a plurality of second hatching paths and a second contour path along the contour of the solid component. The first contour path includes a first hook extending into the plurality of second hatching paths.
