Rapid prototyping is the fast fabrication of a physical part, model or assembly using 3D computer aided design (CAD). The creation of the part, model or assembly is usually completed using additive manufacturing, or more commonly known as 3D printing.

3D printing
3D printing, also known as Additive Manufacturing, is the most commonly used technique for rapid prototyping. Here are 4 different 3D printing technologies for you to choose the most appropriate to manufacture your prototype.

Examples of rapid prototyping: You build the prototype in a room using simple means: cardboard displays, projected images on the wall, small colour changes or an animated digital visualisation showing the new room landscape. Now it’s the turn of the “market research”.

Rapid prototyping provides engineer, design and development teams with distinct advantage such as: The ability to explore and realize concepts more quickly. This efficiency in time and cost allows teams to move beyond the mere visualization of a product, making it easier to grasp the properties and design of a product.

How does Rapid Prototyping Work? Rapid Prototyping, also known as 3D printing, is an additive manufacturing technology. The 3D printing machine reads the data from the CAD drawing and lays down successive layers of liquid, powder, or sheet material — building up the physical model from a series of cross sections.

Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data. Construction of the part or assembly is usually done using 3D printing or “additive layer manufacturing” technology.

There are four main factors that play into a “successful” rapid prototyping workflow. These factors are 1) technology knowledge, 2) application awareness, 3) access to equipment and materials and 4) design for additive manufacturing.

Prototypes are an integral part of engineering product design and more importantly in an overall new product development process. Rapid prototyping can be used at any stage of the product development cycle or for any component or sub-component and can be repeated numerous times along the new product design process.

Cost. It has been said repeatedly, but rapid prototyping is the most cost-effective among the forms of prototyping. This is because you are dealing with low volume production and will not spend as much in the final production model. It allows you to do product testing without great financial risk.

The technology is toolless (eliminating the need for expensive tooling), well-suited to low-volume production and can produce parts in a much shorter amount of time. Rapid prototyping can also help engineers decide on the final design before going to production, reducing the likelihood of costly mistakes.

Rapid Prototyping (RP) enables the quick fabrication of physical models using three-dimensional computer aided design (CAD) data. Used in a wide range of industries, Rapid prototyping allows students to turn innovative ideas into successful end parts rapidly and efficiently.

1980s
Rapid prototyping in the modern sense is often considered to have been invented in the 1980s by Hideo Kodama and Charles Hull with the development of 3D printing. Since then, rapid prototyping has expanded its definition to include various forms of manufacture.

Construction of the part or assembly is usually done using 3D printing or ” additive layer manufacturing ” technology. The first methods for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts.
