Bronze hammer head

This is a bronze hammer head that I made during a metal casting class at my local community college.

I'll add a new post once I get a handle on it after sealing and polishing it.

The part was originally modeled in blender, and printed in PLA on my Creality Ender 3 at home. The layer thickness was pretty large, .2 mm but I wanted to print it quickly and also I didn't think it would show up in the final product, but I'm glad it did

With the pieces all sprued up, we added layers of ceramic slurry to coat the piece and make the mold

The part took 8 coats, we added silica sand with 2 levels of fineness, later cut off the top of the mold and melted out the wax and PLA

The professor melted down some bronze, and poured into the molds

The part came out great and I was thrilled to see this

The sandblaster was having some issues

Finally got the part sandblasted and I ground down the pour spout off camera

Through vinegar fuming in a home Depot bucket, after 5 or 6 hours this beautiful color came out

This was the setup.
