A printing head module includes a bracket, a plurality of printing heads, a pivot shaft, a wiper unit, and a control unit. The bracket includes a plurality of through holes. The printing heads are parallelly aligned with each other, each of the printing heads a nozzle for extruding the modeling material. The pivot shaft connected to the bracket is adapted to rotate the printing heads to a target position. The wiper unit includes a holder, a plurality of wipers, and a wiper opener. The holder is connected to the pivot shaft to be rotated with the bracket and the printing heads. The wipers rotatably connected to the holder and disposed correspondingly to the openings. The wiper opener is disposed at the target position to interfere with the wiper rotated to the target position, so as to drive the corresponding wiper to rotate to the opening position.
