this may be too crazy, but here goes:
Some engineering students receive a emblem called a "bent" that is meant to resemble a bridge truss. I remember it being sand cast in bronze, and you had to polish it. If you contact a university's Engineering College you could ask where they source them. Or you could contact Tau Beta Pi, the engineering society.

Not sure why you want sand cast - the finish is usually a bit coarse compared to lost wax. Some jewelers use lost wax.

Additive manufacturing ("3D printing") is another possibility using the sintered metal process. Others here have much more experience with it than I.
