This type of prototype also gives your stakeholders a clear idea of how the product will look and work before it goes live. Want to get actionable insights quickly and remotely? Discover more about remote usability testing. Rapid prototyping is valuable at all stages of the product development process. Let's take a look at some common use cases:. There are a few best practices to keep in mind to ensure you get the most out of rapid prototyping.
In this section, we explore those best practices and how you can implement them into your workflow. Rapid prototyping is an effective process for building a great product. The feedback you get from users during the product development stage is one of the most significant prototyping and early testing benefits. So next time you struggle with a product idea or want to validate a design concept, try building a prototype and testing it with users—it's guaranteed to reveal at least a few actionable insights.
What is rapid prototyping? Rapid prototyping is an iterative approach to user interface design that can help you test and validate ideas early in the design process. It includes prototyping and testing a design solution with users and stakeholders, and quickly refining and iterating on that solution until final. What are the types of rapid prototyping? Rapid prototyping methods are usually divided into two categories: low-fidelity and high-fidelity prototyping.
Low-fidelity prototypes are basic representations of what your final product might look like and are often used in the early stages of the design process to test concepts and ideas.
They are mainly used to test usability and identify issues and pain points in the workflow. A guide to rapid prototyping: Benefits, processes, and best practices.

There are two types of prototypes: low fidelity and high fidelity. Low fidelity prototypes are rough mock-ups used in the early stages of the design cycle to help designers and engineers understand the form and function of a concept, allowing them to quickly improve on designs.
High fidelity prototypes are nearly exact representations of a final design, used to validate the performance, appearance, and ergonomics of the product. During Fused Deposition Modeling FDM , a heated printing nozzle melts thermoplastic material such as polycarbonate or ABS inside its barrel and then extrudes the liquified material, layer by layer, along a set toolpath.
The process often produces parts that are porous, have non-uniform strength, and have limited functional testing ability. FDM is also slower than stereolithography or selective laser sintering. Still, engineers should consider FDM a viable option during the product development stage, as it provides a cost-effective means for rapid prototyping.
Stereolithography SLA is the tried-and-true rapid prototyping choice for many design and engineering teams. During this process, a computer-controlled UV light laser traces each 2D slice of a part on the build platform, curing a liquid photopolymer resin.
Each completed layer adheres to the next and the process is repeated until a full part is formed. SLA prototypes are commonly used for medical devices and models. However, SLA parts have a much better surface finish than FDM due to the higher resolution of the laser and the reduced appearance of layer lines.
Engineers should consider prototyping with SLA for limited-use parts with intricate designs or higher surface requirements. Light is projected through an oxygen-permeable window and down into a vat of UV-curable resin. Then, a digital device projects a sequence of UV images into the resin, the part solidifies layer by layer, and the full part is formed.
The printed part is baked in a forced convection oven and the application of heat gives DLS printed parts their exceptional mechanical properties. This process is ideal for developing high-fidelity prototypes and small, isotropic parts because the printing process is continuous. They enable us to explore and define the high-level user experience, taking into account the context and specificities of our end-user.
However, when designing a digital product, we need to go further. It is essential to ensure that all interaction flows with the product are consistent and well designed. To accomplish this, we need to make use of a technique known as digital wireframing.
Using tools like Balsamiq, which allows the construction of a static visual blueprint, we can identify potential problems in the user experience, perhaps revealing elements that are not intuitive to our users. Many tools, such as InVision and Figma , allow people with almost no design or programming experience to create a digital prototype. These tools have made it possible to build a high fidelity version of the product, getting it into the hands of target users and tested before it is built.
While additive manufacturing is the most common rapid prototyping process, other more conventional processes can also be used to create prototypes. TWI offers a range of welding support to our Industrial Members, including welding consultancy services and welding technology assistance.

This fast and affordable technique was the first successful method of commercial 3D printing. It uses a bath of photosensitive liquid which is solidified layer-by-layer using a computer-controlled ultra violet UV light.
Used for both metal and plastic prototyping, SLS uses a powder bed to build a prototype one layer at a time using a laser to heat and sinter the powdered material. However, the strength of the parts is not as good as with SLA, while the surface of the finished product is usually rough and may require secondary work to finish it. This inexpensive, easy-to-use process can be found in most non-industrial desktop 3D printers.
It uses a spool of thermoplastic filament which is melted inside a printing nozzle barrel before the resulting liquid plastic is laid down layer-by-layer according to a computer deposition program.
While the early results generally had poor resolution and were weak, this process is improving rapidly and is fast and cheap, making it ideal for product development. Often known as powder bed fusion, this process is favoured for making high-strength, complex parts.
Selective Laser Melting is frequently used by the aerospace, automotive, defence and medical industries. This powder bed based fusion process uses a fine metal powder which is melted in a layer by layer manner to build either prototype or production parts using a high-powered laser or electron beam.
Common SLM materials used in RP include titanium, aluminium, stainless steel and cobalt chrome alloys.
