Despite improvements in process control and repeatability in recent years, quality assurance of additively manufactured parts is a barrier preventing some manufacturers from utilizing it. AM parts may require post-process qualification, which can be difficult, costly, and time consuming. Process monitoring has become an interesting field because of its potential to bring quality assurance upstream from post-process to in-situ, reducing time and cost associated with qualifying AM parts. This technology enables the user to monitor builds in real time, set control limits on the signal it is receiving and stop builds once they're out of control. This saves time and money by eliminating the need to qualify parts that the system has already determined to be outside the process control limits. The EOSTATE Meltpool process monitoring system is evaluated in this study by its sensitivity to process changes, and how these detected changes correlate to material properties and part performance.
