Zusammenfassung:	An alignment method adopted by a 3D printer having a 3D nozzle for jetting material and a 2D pen-module for jetting colored ink is disclosed. The 3D printer first controls the 3D nozzle to print an alignment template on a printing platform, wherein the alignment template comprises multiple alignment blocks respectively and separately printed along an axis, and each alignment block respectively deviates from each center-line according to an accumulated offset. Next, the 3D printer controls the 2D pen-module to print an ink matrix on the alignment template, wherein the ink matrix comprises multiple ink blocks respectively and separately printed along the same axis, and each ink block is exactly corresponding to each center-line respectively. The 3D printer uses covering status of each alignment block and each ink block to determine a deviation between the 3D nozzle and the 2D pen-module, so as to perform an alignment action thereupon.
