The invention provides a method and a system for generating three-dimensional printing data for scanning characteristic parts. The method comprises the following steps: acquiring a plurality of scanning track points of a to-be-printed part; acquiring a plurality of section contour points of the to-be-printed part at each scanning track point, and recording the section contour points as section contour point data; performing coordinate transformation on the profile section contour point data to generate tangent plane contour point data; generating tangent plane distance data according to the distance between the tangent planes corresponding to the adjacent scanning track points; generating printing track data according to the tangent plane contour point data; generating printing speed data according to the tangent plane distance data and preset line width data; and generating three-dimensional printing data of the to-be-printed part according to the printing track data and the printing speed data.
