Physical prototypes can be expensive and time consuming to produce. It may even be a game of “hit and miss” to achieve some optimal composition or optimal physical configuration – no matter how simple or complex the object is. Meanwhile, given the right data and digital modelling it is possible to not only just create virtual products, but also to expose them to a wide range of effects and stress factors in virtual space. 3D techniques based on X-rays have the power to see microscopic or even molecular structure throughout a product or part. Not just the surface. They offer a toolbox to provide detailed physical and structural data, thus achieving greater modelling accuracy and a quicker, cheaper product development.
