Abstract: A 3-D printing apparatus includes a body, a disposed in the body, a control module, a print head module assembled to the body and electrically connected with the control module and a sensing module. The sensing module is assembled to the print head module to move along with the print head module in the body and electrically connected with the control module and includes a probe. The control module drives the print head module to move and causes a part of the body to hit the sensing module, thereby driving the probe to protrude from the print head module to form a first state. In the first state, the control module drives the print head module to move and causes the probe to contact the platform, thereby determining a surface state of the platform.
