What Is Rapid Prototyping?

What Is Rapid Prototyping?

Rapid prototyping means making a physical sample of a new product design idea. This is done as a preliminary step towards eventual production, and is most useful when verifying that the finished product will look, feel, and perform as intended. New product developers turn to rapid prototyping for several reasons. They’re used for functional testing, approvals, design iterations, for crowdfunding campaigns, trade show models, and as a bridge to low-volume manufacturing.

Prototypes often inspire re-designs, improvements, and other modifications that may not have been obvious merely from a computer graphic, so in this regard they’re beneficial for optimizing a design before committing resources to larger volumes. In fact, being able to correct design errors early in the development phase can more than compensate for the cost of the prototype itself, so they’re wise investments.

How Does Rapid Prototyping Work?

Rapid prototyping doesn’t involve a single technology or process. Any of the same manufacturing techniques used to make prototypes can also apply to regular production volumes.
The value comes from making a physical model that closely resembles the design intent, is durable, can be produced quickly, and with a minimal investment in tooling or raw materials.

What Are The Different Types Of Rapid Prototyping?

Any physical model can potentially be a prototype. The difference lies in how closely it reflects the intended finished part.
Very simple models can be made with paper, plastic, modeling clay, styrofoam, balsa wood, or other common household materials. These are examples of very low-fidelity prototypes, but they do have the advantage of being easy and inexpensive to make.
These types of prototypes would likely not function very well or for long, so they’re used primarily to get a visual idea of the design and to compare it in scale to other parts.
More high-fidelity prototypes use modern machine tools and materials, including various 3D printing technologies, vacuum casting, rapid tooling for injection molding, and CNC machining.

How To Choose The Right Rapid Prototyping Technique

The right prototyping method is the one that best fits your budget, the complexity of the part, what you want the prototype to do, and your development timeline. Better prototypes cost more money and take longer to make, but they also more faithfully represent the form, fit, and function of a production part.

The basic questions to ask are these:

* Will the prototype be a static display model?

* Does it need to be fully functional?

* Are there multiple, interconnected parts?

* What is the surface texture and finish?

* What is it made from?

* How important is strength and durability?

* How closely should it match the final production version?

There are many variables to consider and we cannot cover them all here.

We recommend you contact our experts who can advise you
on the method that is best for your application.

  • CNC Machining

    CNC machining is an excellent way to make high-fidelity, end-use prototypes from a variety of raw materials. It’s fast, accurate, and versatile. It’s also easy to make minor changes to the cutting program in order to perfect the final product. CNC machining can also make tapped and threaded holes, which can’t be done with other methods. CNC machined prototypes are full strength, so they’re suitable for engineering testing.

    Finally, it’s possible to make small numbers of housings and enclosures without investing in expensive plastic injection mold tools. However, product developers should note that the corner radii of a machined part will not be the same as a corner made from an injection mold tool. There may be other slight design differences as well, so it’s best to consult us in advance.


  • Vacuum Casting

    Polyurethane vacuum casting molds create up to 30 high-fidelity copies from your original master pattern. Parts can be molded in a variety of resins, including engineering grade plastics, and even overmolded in multiple materials. Vacuum casting is often used as a substitute for plastic injection molding because it is ideal for small volumes of hollow cases and enclosures.

    We’re experts in making production quality cast copies from master patterns. 

    Not only will you benefit from our exceptional attention to detail, but we also provide a full suite of finishing services to bring your part up to showroom quality. Learn more about what our vacuum casting service can do for you.


  • Rapid Tooling

    Our rapid tooling service supports you with high-quality plastic injection mold tools that can be made in as little as two weeks. If you need prototype cases and enclosures for your project, rapid tooling might be the solution. Talk to our engineers to receive a free design for manufacturing review.
