LOCALISING SENSOR DATA COLLECTED DURING ADDITIVE MANUFACTURING

This invention concerns a method of monitoring an additive manufacturing process, in which an object (103) is built in a layer-by-layer manner by directing a laser beam (118a, 118b) using at least onemovable guiding element (150a, 150b) of a scanner (157a, 157b) to solidify selected regions of a mat...

Zusammenfassung:	This invention concerns a method of monitoring an additive manufacturing process, in which an object (103) is built in a layer-by-layer manner by directing a laser beam (118a, 118b) using at least onemovable guiding element (150a, 150b) of a scanner (157a, 157b) to solidify selected regions of a material bed. The method comprises recording position values (Thetan,Phin) generated from a transducer(153, 154) measuring positions of the at least one movable guiding element (150a, 150b), recording sensor values (Sn) generated from a sensor (161a, 161b) for detecting radiation emitted from the material bed and transmitted to the sensor (161a, 161b) by the movable guiding element (150a, 150b) of the scanner (157a, 157b), and associating each sensor value (Sn) with a corresponding one of the position values (Thetan,Phin). 本发明涉及一种监测增材制造过程的方法，在该增材制造过程中通过使用扫描仪(157a，157b)的至少一个可移动引导元件(150a，150b)引导激光束(118a，118b)以固化材料床的选定区域来以逐层方式构建物体(103)。该方法包括：记录由测量至少一个可移动引导元件(150a，150b)的位置的换能器(153，154)产生的位置值(θn，)；记录由用于检测辐射的传感器(161a，161b)产
