It might have been laser sintered metal printing, but my guess is that they printed in plastic, perhaps PLA, then used the “Lost Wax” process for subsequent casting in metal.
There appear to be weld beads on the base & side tube.

A company called Arcam AB 3d prints with titanium using an electron beam. Their stock is going through the roof.
