Parts of this are tailor made for Sigma Labs, i was very happy to hear him mention it as at the time i contacted Sigma to suggest they should look into it but it was my impression they were already well on top of it, and it would suggest that is the case after what Mark said.
For the last few years the military branches have been working on AM both individually but also with regular collaborative meetings to combine findings. Having the US Airforce/Aerojet contract to help qualify AM products for USAF is a fantastic sign of things to come. Sigma have worked with ONR before and fingers crossed will be part of this award, which Mark also added is a "much, much larger call", along the lines of DARPA. Getting in with the Military would be long term, lucrative business, they have big, big plans for the adoption of AM over the next generation.
