  • Publication number: 20160089839
    Abstract: A 3-D printing apparatus includes a frame, a tank, an automatic-filling module and a control unit. The tank is disposed in the frame and contains a liquid-forming material. The automatic-filling module includes a sensing unit, a reservoir, a filling pipe and a pressuring unit. The sensing unit detects a liquid level of the tank. The reservoir stores the liquid-forming material. The filling pipe connects to the reservoir and includes an outlet. A maximum liquid level of the liquid-forming material in the reservoir is lower than or equal to a level of the outlet. A gap exists between the outlet and a top edge of the tank. The pressuring unit provides a positive pressure to the reservoir so that the liquid-forming material in the reservoir flows to the tank. The control unit determines whether the pressuring unit provides the positive pressure to the reservoir according to the liquid level.
