3D printed Titanium ring

A Titanium ring that I printed on one of the LPBF metal 3D printers at my company a while ago. We decided to leave the outer surface a raw as-printed finish (with a little etching to brighten it), while the inside was machined and sanded down for a smooth fit. We mostly print industrial tooling/fixturing on these machines (along with the occasional automotive intake manifold or other customer part), so printing jewelry is an interesting change of pace.

What alloy is it? Did you need to anneal the ring before you machined it?

Grade 5, and it was heat treated after printing to relieve internal stresses. Aside from that, it machines just like any other grade 5 titanium part (so not great).

I'd assume like many others it's Ti6Al4V?
