Title:
LASER SCANNING METHOD AND APPARATUS FOR THREE-DIMENSIONAL OBJECT MANUFACTURING, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/066959
Kind Code:
A1
Abstract:
A laser scanning method and apparatus for three-dimensional object manufacturing, and a storage medium. The laser scanning method comprises: slicing a workpiece to be printed to obtain a cross-sectional profile of each layer, wherein the cross-sectional profile is one or more closed polygons; configuring a plurality of filling vectors for the interior of at least one polygon; selecting all filling vectors, connected to or close to the profile, in a preset area of the polygon configured with the plurality of filling vectors, and controlling the directions of the filling vectors connected to or close to the profile, so that end points of all the filling vectors connected to or close to the profile are terminating points of the filling vectors, and starting points of all the filling vectors are all far away from the profile; and performing laser scanning according to the finally obtained directions of all the filling vectors. The present application can effectively avoid melting pool fluctuation caused by the scanning of starting points of filling vectors, thereby improving the success rate of printing.
