Abstract
A three-dimensional (3D) printing system includes a print engine and a controller. The print engine includes a motorized build platform, a coating apparatus, and a beam forming unit. The controller is configured to perform the following steps: (a) receiving a virtual 3D body, (b) processing the 3D body to define a plurality of N slices, the N slices individually representing intersections of the 3D body with the slice, (c) processing the N slices to represent solid portions of the 3D body with vectors, the vectors defining contours and hatching patterns, the vectors individually bounded by two endpoints, (d) for the individual slices, analyzing a scan speed error for one or more of the plurality of vectors, and (e) for the individual slices, moving some of the endpoints when the scan speed error exceeds a predetermined threshold to provide a speed corrected slice.
