"Preview: Melt Pool Monitoring - monitoring the weld pool
In addition to Powder Bed Monitoring, in future, the TruPrint 5000 machine will come with Melt Pool Monitoring, so that you can supervise the TruPrint machine's LMF process even more efficiently, and evaluate the quality of the components in the most optimum way. Melt Pool Monitoring uses sensors to monitor the weld pool of the laser metal fusion process. Benefit from a detailed quality check and documentation, layer-by-layer. In this way, you can detect any process deviations at an early stage – even in series production – and visualize the critical areas of a component, if necessary. These key figures can be compared automatically with the referenced build job, in order to monitor the stability of the process. Furthermore, when using several lasers at once, you can oversee all of the weld pools in parallel."

they do seem to have their own powdered monitoring tools but no mention of their own melt pool monitoring system

melt pool monitoring on EOS machines

>https://www.eos.info/systems_solutions/metal/systems_equipment/eos_m_400

seems to be marketed only for the EOS M290, check the dropdown menu
that says EOS monitoring solutions available EOS M 400

they do provide Materialise Magic for process control for their machines
