5 Key prototype phases
A common misconception about prototyping is that it is can only be used early in the product development cycle. But the truth is that many engineers use prototyping at various stages to present, test and perfect their ideas. With the advent of online manufacturing services, it has never been easier to produce a prototype quickly and inexpensively. Many engineers know that prototyping is not just for early, rapid prototype development, but can also play a role in various stages of validating a new product. From engineering to sales to market research, having an actual prototype in hand can be hugely valuable in achieving the best project results. To help you perfect the design and save costs, we’ve compiled a list of 5 key prototype phases and which manufacturing processes are best suited for each.
Product concept
Product concept models, or physical mockups, are often used to sell an idea to internal and external stakeholders. The purpose of a product concept is to develop a sales model and is useful in the early stages of product development. At this stage, prototypes can have a variety of prices depending on the manufacturing technique used – from low tolerance CNC work that can be in house within a few days, to more sophisticated and professional looking sales models that can be manufactured through CNC Turning and Milling. Sales models can often be used for marketing promotional materials; you can even get feedback from your customers to improve technical requirements. Best process: CNC turning and milling
Proof of Concept
The purpose of a proof of concept prototype is less cosmetic and more functional. The requirement is to demonstrate the core functionality of the product and prove that the design works as intended. This is often called a tabletop prototype because it can use off-the-shelf items during assembly to save costs and prove product functionality. CNC Turning and Milling is a valuable manufacturing technique that can be used to create a proof of concept. It is not unusual to use different material types to achieve functional goals.

Industrial design
Industrial designs are created to validate the aesthetics, ergonomics or scale of a product. In this phase, the prototype simulates the final product and the goal is to analyze for best usability and overall ease of use. If the design is an electromechanical system, this is typically where engineers are aware of the amount of internal space needed to pack the circuit boards and internal mechanisms, while also considering external features such as cosmetics and ergonomics. There is usually an emphasis on using materials similar to the final product. Best process: CNC Turning and Milling
Functional prototype
The functional prototype is where the proof of concept meets industrial design. This is a product that can be shared directly with a stakeholder for use and feedback. Functional prototypes are typically created even before major investments in production tools are made to reduce costly errors or revision changes. Possible applications include testing aerodynamics, mechanical performance, mechanical properties and thermal performance. Functional prototypes often require end-use durability and smoother surface finishes. Best process: CNC Turning and Milling
Pre-production research
Pre-production models are designed to get into the hands of your early adopters, key stakeholders and potential referrals for your product. This should be a refined version of the functional prototype, made in smaller volumes than predicted production once the product is on the market. Market evaluation should provide any final feedback critical to the success of your product, and internal team members may be working to plan production, assembly and logistics in the supply chain.
