The term “rapid prototyping” refers to quickly fabricating a physical part, model, or assembly using 3D computer-aided design software (CAD). The component, model, or assembly is typically made using additive manufacturing, also known as 3D printing.
A high-fidelity prototype is one in which the design is highly representative of the proposed final product, as opposed to a low-fidelity prototype manufacturing in which significant differences exist.
Rapid prototyping: how does it work?
Many different manufacturing technologies are used in rapid prototyping (RP), but additive manufacturing in layers is the most common. On the other hand, RP also makes use of other technologies like high-speed machining, casting, molding, and extruding.
While additive manufacturing has become the de facto standard for rapid prototypes, other, more traditional methods are still viable.
Involved in these steps are:
Subtractive
Manufacturing process whereby a part is machined from a solid block of material through milling, grinding, or turning. CNC milling prototypes are the most common practice.
Compressive
Such as casting, compressive sintering, and molding, where a semi-solid or liquid material is pressed into place and solidifies into its final form.
What Are The Benefits, Exactly?
Rapid prototyping has many benefits, such as providing a more accurate representation of the final product’s appearance and functionality early in the design and manufacturing process, when it’s easiest to make changes and improvements. Depending on the approach, this can take anywhere from a few days to several months.
Since RP is an automated process requiring less staff to operate, it is also a cost-effective way to test the new design of products via metal and plastic prototype manufacturing. This method is not only highly accurate but also requires no specialized equipment for prototyping each new product and can use computer-aided design (CAD) software to help reduce material waste. Errors in manufacturing can be very expensive, so having the ability to act quickly and solve any problems is essential.
New ideas can be presented to a board, clients, or investors with the help of Rapid Prototyping so that everyone can be on the same page. Additionally, this visualization helps designers quickly get feedback from customers and clients based on a real product instead of a theoretical one.
Due to the iterative nature of rapid prototyping, it is possible to efficiently and cheaply incorporate customer feedback into final designs. This method eliminates the need for one-off product design while giving consumers more freedom of choice and customization options.
What does it cost?
The quantity or size of the part(s), the type of finish desired, the materials employed, and the extent of post-manufacturing processing all play a role in the final price tag.
Conclusion
Companies have been able to identify design problems, evaluate production costs, save time, determine the use of appropriate materials, identify machinery for production, and conduct an infinite number of tests by employing rapid prototyping techniques, as mentioned above in the article Electric Bike
