A printing head module for a 3-D printing apparatus includes a 3-D print head, an ink-jet print head and a baking module. The 3-D print head includes a melting module and a base-material nozzle to print a plurality of staking layers. The ink-jet print head is connected to the 3-D print head and includes an ink nozzle to dispense ink on each stacking layer. The baking module is disposed between the 3-D print head and the ink-jet print head and includes a fan, a discharge casing and a heating module. The fan includes an air-discharge side facing the base to provide an air flow. The discharge casing is disposed on the air-discharge side. The heating module is disposed between the fan and the discharge casing to heat the air flow and the heated air flow being blown out via the discharge casing for drying the ink layer.

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.
