Beschreibung
Zusammenfassung:	An additive manufacturing system (10) includes a first laser device (14) configured to generate a first laser beam (16) and a second laser device (15) configured to generate a second laser beam (17). The laser scanning devices (18, 19) include a first laser scanning device (18) and a second laser scanning device (19). The first laser scanning device (18) is configured to selectively direct the first laser beam (16) from the first laser device (14)s (14, 15) across a powder bed (21) along a plurality of first hatching paths (206) and a first contour path (208) along a contour of the solid component (28). The second laser scanning device (19) is configured to selectively direct the second laser beam (17) from the second laser device (15)s (14, 15) across the powder bed (21) along a plurality of second hatching paths (210) and a second contour path (212) along the contour of the solid component (28). The first contour path (208) includes a first hook (402) extending into the plurality of second hatching paths (210).
