Prototype Manufacturing Process Selection: CNC, 3D Printing, Vacuum Casting, or Injection Molding?

Choosing the right prototype manufacturing methods is one of the most consequential early decisions a product team makes. Get it right and you answer the next engineering question quickly and cost-effectively. Get it wrong and you spend time and budget proving something you did not need to prove — or worse, validating a part that no longer resembles what will actually be manufactured. This guide walks through how to select CNC machining, industrial 3D printing, vacuum casting, or rapid injection molding for a given project, and it explains the prototype process selection logic behind each recommendation. It is not a…
