I found this video showing "AeroJet 3D Printing Dispenser". It looks like some sort of new commercial grade spray depositing 3d printing process. Looks interesting but not much information is available. Hopefully some more information will surface somewhere.
GE developed similar technology but with metal particle spray for industrial manufacturing and repair purposes:
