A private 3D printing project from 2018: an ancient Aztec Medallion.

The model is was first printed in wax, afterwards a negative was formed and the wax was melted. Then liquid brass was injected into the form.
Afterwards it was polished to get rid of artefacts.

I wanted to give it an ancient look, like Roman Bronze weapons you find in a museum, so first I put it into the oven to get a dark grounding and afterwards exposed it to vinegar over a couple of hours to get the verdigris.
Afterwards I only needed to polish the surfaces to make them shine again.
