Have you ever created a physical product prototype?
How did you did it? Did you use a 3D printer? Or the services of a 3D printing company? Or did you go direct to a manufacturer? Or some other method? What advice or recommendations would you give to someone interested in prototyping a physical product?
My buddy has and is using a cnc service at a local metal tech business. He spends 90% of his time waiting for the company to fit in his projects. If he owned the machine he could move forward a lot faster.
There are tons of very talented prototype builders. They are usually called model makers
