THREE-DIMENSIONAL PRINTING APPARATUS

摘要

A three-dimensional printing apparatus is provided. The three-dimensional printing apparatus includes a tank, a movable platform, a light source, a detection module, and a control unit. The tank is filled with a liquid forming material, and the movable platform is movably disposed above the tank. The light source is disposed below the tank and configured to project light on the liquid forming material so as to form a three-dimensional object layer by layer on the movable platform. The detection module is disposed above the tank and includes a signal emitter and a signal receiver. The signal emitter is configured to emit a detection signal. The control unit activates an error-detection mechanism and controls the movable platform to move toward the detection module. The control unit determines whether the three-dimensional object is abnormal based on whether the detection signal is detected by the signal receiver.

1. A three-dimensional printing apparatus, comprising:
a tank filled with a liquid forming material; a movable platform movably disposed above the tank; a light source disposed below the tank and configured to project light on the liquid forming material so as to form a three-dimensional object layer by layer on the movable platform; a detection module disposed above the tank and comprising a signal emitter and a signal receiver, wherein the signal emitter is configured to emit a detection signal and the signal receiver is disposed on a transmission path of the detection signal; and a control unit coupled to the detection module and the movable platform, wherein the control unit activates an error-detection mechanism so as to control the movable platform to move toward the detection module, and determines whether the three-dimensional object is abnormal based on whether the detection signal is detected by the signal receiver.
