Engineering & Technology



Prototyping is the process of evaluating a design (testing out) to see how a product can be improved or if it is suitable for manufacture. Prototyping is used to test:

The advantages of prototyping are:

Virtual modelling

This is where Computer Aided Design (CAD) software is used to produce a 3D model of a design. It allows you to get an idea of how the product will look and also allows the computer to calculate the cost and how mechanical and electronic parts work.

3D Printing
Fused filament fabrication (FFF)

This is a type of  additive manufacturing​ where a model is built up from layers of thermoplastic via a heated nozzle.

3D Printing

This is a type of  additive manufacturing where a model is built up by layers of materials such as resins.

3D Printing
Laser sintering

This is another type of additive manufacturing.  Sintering is a process that causes small particles of metal to join together. A laser is is aimed at a metal powder in a pattern to form a 3D model.

Card modelling

Prototypes can be made by joining and gluing cards, paper and board to make simple models.

Metal Stamping

Modeling foam is supplied in solid blocks. A model can be made by removing material to create the shape you want. This is a type of wasting or a  subtractive manufacturing technique.
