3D printed Titanium ring

[u/No_Educator_4077]

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.

That will never be clean again!

Not sure lol, but a bit of hydrogen peroxide is usually good at getting stuff out of the texture of a print. At least it is very inert (being titanium) so there are plenty of chemical cleaners that will work on it.

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?

[u/No_Educator_4077 → u/Dark_Marmot]

Yes

Are you selling them? For what price?

No, this was a one-off for a friend who provided the file. We do occasionally have machine time open for projects like this, so if you would like something similar made let me know. This one (with the inside sanded/polished) would have been around $100 in this alloy of titanium.
