A 3D printing device (100), which is adapted to print a second object (20) on a first object (10). The 3D printing device includes a body (110), a 3D printing unit, a sensor unit (130), a storage unit (160), a control (140) unit and a carrier plate. The control unit is electrically connected to the 3D printing unit, the storage unit and the sensor unit. The storage unit stores initial coordinates, and the initial coordinates correspond to an initial printing position of the 3D printing unit. The carrier plate (150) is located at a bottom of the body and has a ocular mark. The first object is adapted to be placed on the carrier plate. The sensor unit senses a height of the first object relative to the carrier plate, and the control unit drives the 3D printing unit to print the second object on the first object according to the height and the initial coordinates. |
