Laser additive manufacturing method and system

The invention discloses a laser additive manufacturing method and system. The method comprises acquiring a three-dimensional model of a product, slicing the three-dimensional model according to a preset height threshold to obtain a plurality of slice bitmaps, wherein the slice bitmaps include a plurality of pixel points, determining positions of all the pixel points in the three-dimensional modelto obtain position information corresponding to all the pixel points, marking gray values of all the pixel points according to the position information corresponding to all the pixel points, accordingto the gray values of the pixel points, calculating laser power of each one of the pixel points, and carrying out scanning and printing on areas where the pixel points exist according to the laser power of the pixel points to obtain a three-dimensional printed model of the product. The method and system ensure the uniformity of the laser scanning filling and improve the quality of the product. 本发明公开了种激光增材制造方法及系统。该方法包括：获取制
