From Idea to Prototype: A Step-By-Step Full 3D Printing Workflow

What you need to know: China-based companies offering 3D printing prototype services follow a specific workflow but can adjust their process depending on your requirements. Talk to HLH Prototypes to receive a tailored production plan for your part.

A 3D printing prototype service can help you move from a digital design to a physical prototype within days or even hours. So, you don’t have to wait for weeks or months to get your model or pay for tooling before you’re ready. You can test your ideas early, make changes quickly and catch potential problems before they become more expensive to fix.

Here’s a step-by-step look at how a 3D printing service can turn your idea into a prototype.

Step 1: Develop your concept and design

Design your CAD model around the specific thing you want the prototype to test. For example, if you want to check whether parts fit together correctly, model those interfaces accurately. If you want to test how a feature works, include enough detail to evaluate that feature.

Step 2: Pick the right 3D printing method

A 3D printing prototype service should be able to offer different technologies to fit your project. For example, they may recommend one process for testing how a part performs and another when you need a highly detailed model for visual review.

Step 3: Choose your materials

The material you choose should ultimately depend on what your prototype needs to do. If you’re mainly using the prototype to judge how the final product will look, choose a material that can produce a smooth surface and fine visual detail. For functional testing, you might need a stronger or more flexible material that can better mimic how the final part will perform.

Matching the material to your testing goals gives you more useful feedback from each prototype.

Step 4: Print your prototype

This is where the 3D printing prototype service turns your CAD model into a physical part.

During printing, the printer builds your prototype one layer at a time. Factors such as orientation and resolution can affect how it turns out and overall production time.

If testing uncovers a problem, you can simply update your digital model and ask the service provider to print another version. You don’t have to start the entire production process again, which makes repeated testing much easier.

Step 5: Post-process your part

After printing, your prototype may need some final work. A reliable 3D printing prototype service can take care of that, from removing supports to cleaning the part and smoothing surfaces.

How much finishing you need depends on what you’re testing. You might not need a highly polished surface if you only want to check dimensions or fit.
