IN-PROCESS MONITORING IN LASER SOLIDIFICATION APPARATUS

The invention concerns a laser solidification apparatus for building objects by layerwise solidification of material. The laser solidification apparatus comprises a build platform (102) for supportingthe object (103) and a material bed (104), an optical module (157) comprising a movable guiding element (150) for directing the laser beam (118) to solidify material of the material bed (104), and adetector module (160) comprising a sensor (161) for detecting radiation emitted from the material bed (104) and transmitted to the sensor (161) by the movable guiding element (150) of the optical module (157). The detector module (160) is removably mounted to the optical module (157). 本发明涉及一种用于通过材料的逐层固化来构建物体的激光固化设备。该激光固化设备包括：构建平台(102)，该构建平台用于支撑物体(103)和材料床(104)；光学模块(157)，该光学模块包括可移动导向元件(150)，该可移动导向元件用于引导激光束(118)以固化材料床(104)的材料；以及检测器模块(160)，该检测器模块包括传感器(161)，该传感器用于对从该材料床(104)发射并通过该光学模块(157)的可移动导向元件(150)传输到传感器(161)的辐射进行检测。该检测器模块(160)可移除地安装于该光学模块(157)。
