<P>PROBLEM TO BE SOLVED: To provide a three-dimensional shaping apparatus capable of surely detecting that waste liquid in a waste liquid tank exceeds a certain amount while preventing increase of manufacturing cost. <P>SOLUTION: This three-dimensional shaping apparatus includes: an accumulation amount detection sensor for detecting an accumulation amount of waste liquid in a waste liquid tank 13H; a waste liquid pipe having one end arranged in the waste liquid tank 13H and the other end connected to a purge tray 114; a waste liquid pump 60 allowing the waste liquid in the purge tray 114 to flow into the waste liquid tank 13H; a pressure sensor for measuring pressure in the waste liquid pipe on the waste liquid tank 13H side relative to the waste liquid pump 60; a liquid level detection part 408 for detecting that the liquid level in the waste liquid tank 13H reaches one end of the waste liquid pipe based on output of the pressure sensor in reverse rotation of the waste liquid pump 60; and a waste necessity determination part 411 for determining whether the accumulation amount of the waste liquid in the waste liquid tank 13H exceeds a certain value based on the liquid level detection result or the detection result of the accumulation amount detection sensor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
