There are two abbreviations thrown around a lot in design and manufacturing industries, these are CAD and CAM. Firstly CAD stands for Computer Aided Design, it’s used in 2D and 3D design on computers, as we are talking about 3D I’ll explain the uses of CAD in regard to 3D. CAD is generally used to create curves, solids and surfaces in 3D objects, many everyday objects are originally created using CAD such as the hairdryer below which was created on a CAD program called Maya, made by Autodesk.
This blackberry mould is an example of what can be produced using a CNC Machine. These moulds are amazingly close to the actual model they are based on and are identical to the model that has been created on a CAD machine that has been transfered to CAM.
