Like I said Alan, I don't know much about this but after reading about DARPA's program to encourage and assist small companies with new technology - it does seem very probable that SGLB would be a recipient, in my opinion.
Just as quality and repeatability of manufactured parts or items will be of significant importance to commercial industry, it will also make many more things possible for our government / military. Like 3D printing a wrench at the Space Station earlier this year, for just one example.
Perhaps other SGLB longs here will do some DD on this potential with DARPA and provide more information for all.
Many thanks.
