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…
How to Choose the Best Prototyping Method for Your Project: CNC, Vacuum Casting, 3D Printing, or Injection Molding
You need to know how to choose the best prototyping method for your project. Your goals, materials, how many you need, budget, and time all matter. Matching the method to your needs helps users get better feedback. Picking the right way lets users see ideas come to life. It helps users agree on choices. It also lets users spot problems early.
