What are the limitations of rapid prototyping?

Rapid prototyping is one of the key processes in an industrial designer’s repertoire. Unlike traditional design processes, rapid prototyping gives industrial design the edge of being able to predict possible product outcomes and tweak and edit as needed if the initial prototype show signs of needing improvement.

However, this highly developed process, as much as it provides incredible insight into a product’s development and concept, is not without its limitations. This does not in any way mean that the prototyping process needs to be left out completely during the design journey of a product, but rather that industrial designers need to be aware that the process has some restrictions.

In today’s blog, we will be looking at the limitations of rapid prototyping, whether the process has any disadvantages and what the main disadvantages of high-fidelity prototyping are. But, before we delve into these subjects, let’s first have a look at why rapid prototyping is so important for industrial designers.

Understanding the importance of rapid prototyping

Rapid prototyping not only gives a valuable preview of a planned product’s end results – it also fast-tracks the design process as it speeds up product development and gives a preview of how a product’s design will achieve success in line with your client’s goals.

Because rapid prototyping is such a productive experience, it allows clients to have a better scope of how a product design will ultimately be envisioned and where there are areas where tweaks can be made. It also enhances the client and industrial designer relationship as there is trust and rapport that a client’s best interests are at the core of the designing process.

However, despite all these benefits, there are some limitations to consider too. Let’s take a look at some of the aspects that are important to bear in mind when rapid prototyping forms part of the scope of a project.

Limitations and disadvantages of rapid prototyping

Although disadvantage is a phrase that an industrial designer would ideally not associate with rapid prototyping, it is a reality that this process has its limitations. Here are some aspects to consider -especially when communicating the findings of rapid prototyping:

1. Rapid prototyping provides a good precursor for a product’s projected outlook, but it is not a 100% view of how a final product will look

Bear in mind that rapid prototyping is but a first step in analysing a product – there might still be variations and tweaks and the final product will likely not 100% resemble the created prototype. So, always bear in mind that an early prototype design could still go through further changes.

In order to avoid confusion, make it clear that the prototype is not the final prototype version, especially as the range of materials used for prototypes are often limited or of certain finishes for an end product cannot be matched with a prototype.

2. Rapid prototyping could add additional costs to a project

Rapid prototyping, as cost-effective as it is, still calls for additional materials for producing prototypes which, together with added labour costs, will need to be factored into client budgets. Some rapid prototyping processes could be expensive depending on scale, and clients will need to be informed upfront to ensure that there is an understanding of why these prototypes validate certain costs.

3. There could be a delay in deliverables

Complex prototypes could lead to longer turnarounds, especially if a designer needs more time or information if an initial brief was unclear or expectations were not communicated fully. Also, in products where multiple features need to be completed, the process could become significantly complex.

4. Rapid prototyping is not used for mass production and cannot produce large quantities of products

Rapid prototyping is by no means an opportunity to step into mass production – only the final product design will head into production. Therefore, expectations will need to be managed, clearly stating what the next steps are as soon as a design is signed off.

High-fidelity prototypes more closely match final products and can give a bigger scope of how customers will interact with these products. However, these more precise product previews could lead to higher costs and time for development. Granted, because these designs offer better insight into a final product’s look and feel, the value of getting more detailed feedback will ensure that a product is on the right track.

Should rapid prototyping remain part of the equation?

Ask any industrial designer, and they will tell you: absolutely! As much as the process has limitations, it is a perfect springboard to take a product a step beyond the concept phase and start the process of design, review and updating.

Without rapid prototyping, some aspects of an intended product that need modifications could be overlooked, resulting in a final product of which the design could have been improved before production started!

Ultimately, rapid prototyping is a value-added service that industrial designers offer to clients, and the rewards of preplanning, adjusting and adapting cannot be denied. The value that clients receive is not only receiving their desired products after final production, but also have their finger on the pulse of any changes that need to be made to ensure that their products will be viable for markets.

And that is why, despite its limitations, rapid prototyping is a must – no matter the scale of a project!
