CNC manufacturing prototypes are used in many industries and there is always a need for a functional prototype or at least a version that can demonstrate how the real product works. CNC machined prototypes are the best fit. In addition to brass, the materials that can be used for prototyping include steel, aluminum, titanium, plastic, etc. CNC technology can process these materials into any complex precision parts you want. CNC prototyping is a great option because it can produce a small number of prototypes in a relatively short amount of time compared to other methods.
