Found this in my box of desk trinkets, and thought to share.
From what I remember, my father was given this demo print at some tech show in mid-2000s. I am not sure of the material used for it. The surface is rough, dry, and porous, slightly discolored, but does not appear to be crumbly, flaky, or brittle even after 20 years. My friend suggests it might be made with powder sintering.
Definitely binder jet printing. You don’t get that finish with SLS. Even from that time.
Sauce: I was there when it was all the rage
