Nice. Thank you for the link wickw50. Here's the quote Herringaid and silversmith are referring to.

Prabhjot Singh: GE recognizes the vital role of in-process quality assurance in maturing AM technology. This is an active area of development.

The key challenges in implementing this technology for powder-bed AM processes, such as DMLM and EBM, are the development of high speed sensors, which can keep track of the laser/electron-beam which typically moves at 1-2 m/sec, data analytics methodologies capable of processing gigabytes of data created by these sensors, and the successful integration of these sensors with commercial machines.
