Rapid prototyping

To help develop this article, click 'Edit this article' above.

A recent technology, since the 1980s this has been an important asset for countless industries and projects that need an extra level of rendering to enhance work done.

An additive process – rapid prototyping uses materials such as adhesives and photopolymers – by joining particles and layers of raw materials together to create the desired shape. It differs from more traditional processes, which typically compress and subtract rather than add.

First, a virtual 3D model must be created using CAD software. This digital rendering is a simulation of the final product. The design is then converted so that the prototype can be printed as efficiently and accurately as possible – allowing the printer to interpret the design in a language it understands. Checks are needed throughout the process to ensure no mistakes are made during printing.

There are a number of benefits of rapid prototyping:

Short turnarounds.
Accuracy ensured before the final product is constructed.
Cost-efficient.
High-quality product.
It can produce small parts and cavities.
It allows issues to be corrected at the beginning of the process rather than carrying them into the final product.
It is 'eco-friendly' as it generates less waste.
