Abstract
A three-dimensional printing apparatus including a chassis, a tank, an outer cover and a shielding module is provided. The tank is disposed at the chassis and adapted to be filled with a liquid forming material. The outer cover is pivoted on the chassis. The shielding module includes a pivot and a mask. The pivot is disposed on the chassis and beside the tank. The mask is winding on the pivot and connected with the outer cover. When the outer cover rotates to a first position and covers the tank, the mask is winding on the pivot. When the outer cover rotates to a second and exposes the tank, the outer cover pulls the mask out of the pivot, so that the mask covers the tank in order to shield the liquid forming material filled in the tank.
