Micro-tomography has been widely applied in material sciences to study micro-structures. This technology, altogether with Digital Image Processing, allows rebuilding 3D virtual models of the scanned objects.

3D virtual models can be redesigned into jewellery, demonstrating that a natural complex structure, which is difficult to obtain through conventional CAD modeling, light or infra-red scanning, may now have its aesthetics appropriated by design with the aid of a micro-tomographer. Additionally, 3D printing is an optimum fabrication process to make direct-casting models with complex structures.
The objects are a result of an experimental research that focused on exploring characteristics of Micro-tomography, Digital Image Processing and 3D printing, that together excel conventional jewellery fabrication aspects. These distinctions can be described as geometrical complexity and designing from forms with particular natural aesthetics. Jewellery designers are compelled to shift creation from physical to digital, yet this work attest that the designer must also be able to complement and correlate both digital and traditional knowledge to lead to innovation in this field.
