Eventually, PERT will be done. Also, I'm comfortable at any PPS. Sigma Labs will continue to progress regardless of PPS. The relationships they've built will continue to grow. Where are the 2 systems? Boeing, Honeywell, or GE? Who knows. What we know is that the aerospace industry is a $209 Billion market with growing backlogs aerospace manufacturers need to fill. We are only seeing the tip of the iceberg. 2 PrintRite3D systems for $975,000. That is fantastic! GE plans on building a plant with 40+ 3D printers (can't recall exactly). And that is just GE alone. PrintRite3D shaves 25-30% of manufacturing time and the Metronics 3D scanner is AS 1902 compliant. We are in good position no matter what PPS.
