You have a CAD file. It needs to become a real part.
This process is plastic prototyping. Getting it right saves you time and money. Getting it wrong causes major headaches. This guide will show you how to get it right.
The technology you choose depends on your goal. There are three main options.
CNC Machining Need a strong part? One that acts like the final product? Use CNC machining. It carves your part from a solid block of plastic. The result is tough and accurate. It’s the best choice for functional testing.
3D Printing What if you need it fast? Or the shape is complex? 3D printing is the answer. It’s built for speed and quick design checks. Perfect for early-stage models when you are making lots of changes.
Vacuum Casting Need a small batch? Maybe 20-30 parts for a meeting? This is the job for vacuum casting. It is a smart part of plastic prototype manufacturing that gives you multiple high-quality copies without high tooling costs.
Why Your Material Choice Matters
The material is half the battle.
Your test results are useless if the material is wrong. If your prototype plastic parts need to be strong, you must use a strong plastic like ABS or Nylon. If they need to be clear, you must use a clear material like acrylic. The material has to match the part's job.
How to Pick Good Plastic Prototype Makers
Your choice of partner is important. Some plastic prototype companies are much better than others.
Here is what to look for:
They offer many technologies. A shop with only one machine will sell you that one process. Every time. You need a partner with options who can give you honest advice.
They check their work. How do they inspect parts? Ask if they use a CMM (Coordinate Measuring Machine). It’s a sign they are serious about accuracy.
They give you feedback. The best partners don’t just take your file. They review it. They might call you with suggestions to make the part stronger or cheaper to produce. This feedback is incredibly valuable.
Smart choices in plastic prototyping protect your project from risk. You find problems early, when they are easy to fix.
