@Sculptingman, I contacted the local foundry, and they DO take .stl files, print, and cast. I don’t know if they’ll cast a pre-existing model…she talked about a material that I didn’t recognize. They do large-scale art foundry casting.
The only problem is that the turnaround is 12 weeks. However, being near Austin, it sounds like they are up on the latest technology. I told them your project was small, and she said it would still take 12 weeks…not sure if they could work it in.
Another possibility is Shapeways, although I don’t know about their bronze capabilities as far as casting. They use a sintering technology for some of their bronze.
The company name is Deep in the Heart of Art (a play on “Deep in the Heart of Texas”).
