The invention provides a leak detection device and a leak detection method used for a vacuum chamber system of 3D printing equipment. The leak detection device comprises a helium mass spectrometer, adetection tooling, and the vacuum chamber system to be detected. In addition, the vacuum chamber system in the leak detection device is a vacuum chamber system maintaining a gastight environment, andcomprises a vacuum box, and a material box, a filter, a blower, a helium gas tank and a vacuum pump which are connected with the vacuum box separately, a pipeline connecting the filter and the blower,and a sealing door. Therefore, the gas-tightness detection can be conducted on the 3D printing equipment in a working state, thereby manufacturing the 3D printing equipment with good gas-tightness. 本发明提供种用于3D打印设备真空室系统检漏装置及检漏方法，该检漏装置包括氦质谱仪、检测工装、以及待检测的真空室系统。此外，上述检漏装置中，所述真空室系统是保持气密性环境的真空室系统，其包括：真空箱；分别与所述真空箱相连的料箱、过滤器、鼓风机、氦气瓶、真空泵；连接所述过滤器和所述鼓风机的管路；以及密封门。由此，根据本发明能够在工作状态下对3D打印设备进行气密性检测，从而制造出气密性良好的3D打印设备。
