Rapid Prototyping and 3D Printing: Everything You Need To Know

Rapid prototyping and 3D printing are truly a match made in design heaven!

Rapid prototyping is a common prototyping process used across many industries. Using a 3D printer for prototyping is a smart way to save time and money while also expanding design possibilities. It allows companies to physically conceptualize designs and ideas quickly and at a low cost.

In this article, we’ll dive into how 3D printers can be used for rapid prototyping, and everything else you need to know about how these two concepts work together.

What is Rapid Prototyping?

Rapid prototyping is the general term used for the process of quickly creating prototypes and models. This type of prototyping can be done in many different ways and involve several techniques. 

As its name implies, this style of prototyping allows designers to quickly see the functionality and test the effectiveness of a design, as well as compare variations. Whereas traditional prototyping may take a lot of time and materials, rapid prototyping typically involves methods that are much quicker and cost-effective.

One of the most popular forms of rapid prototyping is through 3D printing. Many industries, including engineering, architecture, and manufacturing, utilize 3D printing in their rapid prototyping processes to speed up their workflows and save money. 

Sometimes the terms rapid prototyping and 3D printing are used interchangeably, which is incorrect. Rapid prototyping is a technique, while 3D printing is one of the technologies that can be used for this technique. While prototyping is a very common use of 3D printers, this technology is also suitable for many other uses and applications. 

The Role of 3D Printing

Using CAD software and a 3D printer, rapid prototyping can be taken to new heights. 3D printing is one of the most common prototyping methods today, simply due to its major benefits. 

One of the largest benefits of using 3D printing for prototyping is its ability to save time and money. Instead of paying an external manufacturer for every iteration and design, 3D printing allows you to save waiting time and manufacturer costs. Designers no longer have to wait days or weeks to see a functional prototype and can quickly make changes on the spot.

Depending on the print job, a design can be printed in a matter of minutes or hours. If a model is going to be particularly large, you can leave the 3D printer on overnight, allowing you to come back to the office to a fully printed prototype, freeing up space for the next one.

Rapid prototyping with a 3D printer allows designers to keep their concepts in-house. This not only speeds up the workflow, but it keeps ideas confidential and secure. 

But perhaps the most valuable role of 3D printing for rapid prototyping is the ability to test and compare different models or design ideas. This applies when testing both functionality and aesthetics.

If you use a more durable filament like PA or TPU, or filament that is similar to your end-use material, you can test whether your design will stand up to elements or factors that are important, such as certain chemicals or the weather. Similarly, 3D prototyping allows you to physically compare different visual concepts and iterations. 

Applications of 3D Prototyping

Many industries currently incorporate 3D printing into their rapid prototyping workflow. 

Architects and product designers can utilize this technology for building models as well as showcasing difficult designs that may not be accurately represented on a screen alone. Engineers and manufacturers can utilize additive manufacturing for functional prototyping, which allows them to test different technical aspects of a tool or part.

Students and researchers also benefit from the speed and versatility of 3D prototyping, as demonstrated by Instituto Europeo di Design Barcelona

Using 3D printers in their classrooms, students at IED Barcelona can quickly compare different ideas and concepts before settling on a final design. In their very classrooms, they are recreating the real-world effects of using 3D printing for prototyping. 

Final Thoughts

Using 3D printing to speed up your rapid prototyping process will revolutionize your prototyping workflow. The saved costs and time, combined with an easier design testing process, makes additive manufacturing one of the best technologies for prototyping.
