No cnc needed for simple patterns. If you can cut wood to dimension, you
can do the same with foam. you can glue it together just like wood.
Some patterns may need bracing to keep them straight, but that isn't a
huge problem.
Another thought is for people with the patterns. Maybe you might want to
sell casting kits. Works for steam engines.
