Q.What is Rapid Prototyping?

Rapid Prototyping techniques offer multiple benefits, such as:

Fast and effective communication of design ideas

Effective validation of design fit, form, and function

Greater design flexibility, with the ability to run quickly through multiple design iterations

Fewer production design flaws and better end-products!

Rapid Prototyping - A Quick History

Rapid prototyping systems emerged in 1987 with the introduction of stereolithography technology, a process that solidifies layers of ultraviolet light-sensitive liquid polymer using laser technology. In subsequent years, other rapid prototyping technologies were introduced, such as: Fused Deposition Modeling, Selective Laser Sintering and Laminated Object Manufacturing. The industry’s very first 3D rapid prototyping system based on inkjet technology was introduced by Objet in April 2000.

How does Rapid Prototyping Work?

Rapid Prototyping, also known as 3D printing, is an additive manufacturing technology. The process begins with taking a virtual design from modeling or computer aided design (CAD) software. 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. These layers, which correspond to the virtual cross section from the CAD model, are automatically joined together to create the final shape.

Rapid Prototyping uses a standard data interface, implemented as the STL file format, to connect between the CAD software and the 3D prototyping machine. The STL file approximates the shape of a part or assembly using triangular facets.

Typically, Rapid Prototyping systems can produce 3D models within a few hours. Yet, this can vary widely, depending on the type of machine being used and the size and number of models being produced.
