Every once in a while the Foundry graciously opens for Arcosanti residents to create their own bronze artwork, with assistance of the foundry crew.

Here is a report by Rob Jameson [IT & Web here at Arcosanti], about the recreation pour last Saturday, December 17. 2016:

“Last week I met with Andy, the manager of the Foundry, to discuss objects that we could 3d print and then cast in the foundry. He helped me simplify from 20 ideas to about 8, by teaching about undercuts and some of the tactics for impressing them in the sand.

That night, I did 3d prints around the clock to get a full fleet out. I 3d printed various geometric patterns, objects, and images into solid plastic models. The printer was running right until the beginning of the foundry work. [photo by Leah-Ann Walker]

I brought the printed pieces to the Arcosanti Foundry, where 3 staff helped me prepare my piece. The plastic had ridges, so Charlie blow torched it smooth. Brendan helped me revise my structure for the chalice.

Then Ali did all the molding in sand! It was very challenging to get the sand not to stick in the details of the 3d print. In hindsight, all walls should be slightly non-vertical… this lets sand slide off easier.

We poured 2 boxes with 11 objects… the result was fantastic and accurate in places where the bronze reached. Ali finished some of the pieces so they are more refined. I weighed them and paid a very fair cost for the material and fuel.”
