Great post, and I think you've hit the nail right on the head. They have indeed protected themselves with different major players involved with different components of what make up PR3D. Plus having that connection and access to LANL personnel, and R&D is huge and almost an unfair advantage, but obviously in a good way for us. In my opinion that is why all the competitors have essentially camera/optical based systems, while Sigma Labs has the trio, (optical, thermal & acoustic) with years of materials science to back it up.
