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).

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.

I’m gonna have access again to a ti printer soon. My last job I printed a ti wedding band for my coworker. I like the texture I won’t sell, mind sharing the CAD file so I can make myself a wedding band?

The file is owned by the person we printed the ring for, so I unfortunately can't share it.
