"A process for producing a titanium load-bearing structure, which comprises cold-gas dynamic spraying of titanium particles on to a suitably shaped support member, and a titanium load bearing structure so-produced."

It's not actually 3D printing 'per se' but a different form of additive manufacturing. It requires an existing "support" that the titanium powder can sprayed on to and then melted.
