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.
