Abstract
A method of slicing and printing multi-color 3D object is provided. The method includes following steps of: loading a coordinate information and a color information of a multi-color 3D object; executing a slicing process to generate a plurality of object printing slices and a plurality of object images; generating a plurality of pollution-blocking printing slices and making each pollution-blocking printing slice partially overlap an edge of the same-layer object printing slice; controlling a modeling nozzle of a multi-color 3D printer to print the object printing slices layer by layer, printing each pollution-blocking printing slice partially overlapping the same-layer object printing slice after the same-layer object printing slice is printed, and controlling a coloring nozzle of the multi-color 3D printer to color each of printed object printing slice after the same-layer pollution-blocking printing slice is printed.
