Titomic 3d printing pre-ipo, page-28

If you look at their website there is a demonstration video. It's a cold spray through a nozzle but it needs a structure to spray on to as the video demonstrates. It coats an existing structure with the metal powder.

It's not actually building a 3D part from ground up like a metal 3D printer does.
The cynic in me says that we will see many additive manufacturing and 3D plays come to market on the back of what A3D has done in terms of share price performance. It's an exciting new industry and becoming a hot space with General Electric (GE) becoming aggressive with recent billion dollar offers for exisiting 3D printing companies.
