An inspection technique where sensors are placed inside an additive manufacturing system’s build volume to measure different aspects of the build process while it is taking place. Infrared cameras are usually used to capture precise temperature values across each build layer over time.
This provides detailed feedback on the process and part as it is constructed. Some additive manufacturing systems use this information to modify build parameters in real-time, others to detect flaws or problems with the build or the final part. The data can also be combined over multiple builds to improve processes.
Also called in situ inspection and is most common in powder bed fusion systems.
