The concept of prototyping for innovation has been around for centuries, since the time inventors felt the need to test and improve their ideas through physical models. The word prototype is derived from the Greek prototypon, meaning “primitive form”.
Prototyping is an experimental process that transforms an idea into a tangible product. As an integral part of design thinking, it allows innovators to visualise, experiment, learn, and adapt their ideas.
Prototyping encompasses a variety of methods and approaches, each serving distinct purposes across different stages of product development. It can be applied to product design, software development, architectural design, engineering and industrial design, UX and UI design, and R&D. In this blog, we focus largely on prototyping in relation to manufacturing, exploring how it supports the validation and optimisation of production processes.
A prototype is an early version of a product to test and validate the design concept and draw feedback from internal and external stakeholders. Based on the feedback, the initial version lends itself to incremental improvements before culminating in the final product.
Like many creative processes, prototyping too demands considerable time, effort, skills, and vision. It ensures that an innovator-entrepreneur is on the right track in building a product that addresses a specific problem/need of its target market. There has been a sea-change in product prototyping with rapid technological strides in 3D printing but more on that later.
What looks good on paper or in the mind could prove to be a disappointment in real-world environments where the final product is used. Hence, there is a need for a mock-up that might highlight the omissions or inadequacies that were not evident earlier.
Prototyping is an inexpensive way to iron out design defects and test the efficiency of the product before it is sent for mass production. Since it is an iterative process, designers and engineers have the opportunity to incorporate suggestions from stakeholders early on to ensure that what they are creating will be liked and used by people to improve their lives.
Without prototyping, a startup or even a well-established company would be prone to committing the cardinal error of building something that is either inefficient or has little use in the market. For the company that can lead to considerable financial losses and a waste of time, effort and valuable resources.
Among many other things, prototyping also helps define the objectives of the product development team. An innovator will utilise the process to gain an in-depth understanding of the needs, pain points, and preferences of the product’s end users.
Additionally, prototyping affords the opportunity to critically examine design viability and the technology used for building the product. It also eliminates misunderstandings and miscommunication during the development process.
It’s no wonder, then, that it is often said that just as a photograph is worth a thousand words, a prototype is worth a thousand meetings, as it makes it easier to convey an idea to stakeholders such as company decision-makers, investors, clients, marketing and sales teams, and others.
Prototyping before mass manufacturing is crucial for several reasons. These include:
Fidelity indicates a prototype’s position vis-a-vis the “finishing line”. In other words, the level of completion the model has achieved in terms of design, features, functionality, and sophistication. Fidelity depends on the stage of progress in the product development journey and the purpose for which the prototype is being built.
Prototypes can range from low to high fidelity.
Low-fidelity prototyping allows for quick and cost-effective ways to validate the hypotheses and carry out refinements. Ideal for the early stages of product development, low-fidelity prototypes empower innovators and designers to create and test as many prototypes as they want. With the rise in design thinking and lean start-up methodologies, such prototyping has increasingly become popular.
It refers to an advanced stage in the development journey, where the model is much closer to the final product, rich in visual details and actual content. High-fidelity prototyping is used by designers to showcase key design features, interactivity, and workflows to important stakeholders for approval and input.
It represents the middle ground – between low and high fidelity – one that offers more details than basic paper prototypes. Though it comes with limited functionality, it still gives a fair idea of the interactive elements of the product.
3D printing is a versatile technology for quickly and cost-effectively creating physical prototypes. It supports various purposes, including visualisation, functionality testing, and design iteration. By enabling rapid production, 3D printing helps designers and engineers make informed decisions and refine their designs efficiently.
Advancements in 3D printing have transformed prototyping by reducing labour-intensive tasks, saving tooling costs, and offering design flexibility. It speeds up design iterations, supports on-demand prototyping, and ensures high-quality output while optimising material usage.
3D printing gives product developers the freedom to work with a variety of materials – from plastics (ABS, PA-nylon, polycarbonate and polypropylene) to metals (aluminium, cobalt chrome, Inconel, stainless steel, titanium) – and test prototypes under real-world conditions. This means that those using 3D printing for prototypes can bring their products to market much faster, gaining a significant edge over those using traditional manufacturing methods.
Rapid prototyping in 3D printing creates non-final product versions to quickly test design ideas and gather data. As the name suggests, speed is of the essence in such a process, where designers explore various materials, sizes, shapes, and colours to assess their impact on form, fit, and function. New 3D designs can be printed in just a few hours, providing insights that enhance the final product. This method is widely used in industries such as defence, aviation, astronomy, healthcare, robotics, mechanics, and civil engineering.
3D printing costs can vary widely, depending on a host of factors, including the quantity and type of the material used; volume, size, and complexity of the model; and the technology and time used for making a 3D model.
Prototyping has increasingly moved towards integrating virtual and physical prototypes to reap the benefits of process streamlining, cost reduction, and product performance improvement. As products get more complex and integrated, innovators are faced with the task of creating the next generation of prototyping tools and technologies that can create more technically advanced products while further streamlining the process and engaging users.
Experts believe that the convergence of AI-ML and specialised materials will push the boundaries of prototyping, bringing in more efficiency, accelerating production, and enhancing the quality of both prototypes and final products. This, in turn, will pave the way for an innovative and planet-friendly future.
