These 2 PrintRite3D systems, wherever they may be, may be used in the evaluation of 3D printers.  There's competition between EBM and SLS machines and their efficiency.  Why else the purchase of 2 machines?  GE was reported to use EOS and Arcam which uses laser and electron beam respective.  GE is now testing Concept Laser.  The PrintRite3D systems must be evaluating the difference in addition to adding in-process control to manufacturing.  The 3D printing machine that does not require as much manipulation from PrintRite3D will be the more efficient and better solution to increase production:
