Recent developments in Additive Manufacturing (AM) technologies allow geometries to be fabricated at higher complexities and at smaller sizes, however, currently available Computer-Aided Design (CAD) methods and software packages do not facilitate these changes. High-performance, functional parts are designed and optimised with consideration of manufacturing limitations. As developments are made within manufacturing, so should the precursory design processes. This research was completed to advance the field of CAD, also in the field of functional textures, so that new potentials provided by AM technologies can be realised. Functional textures can be summarised as solutions that manage the environments that surround them, so that specific performances of textured objects are improved. Many naturally occurring textures exhibit overhanging geometries to achieve their optimised functionalities. Prior to AM these geometries could not be reproduced accurately by manmade designs and available manufacturing methods. A novel CAD method has been developed as part of this research to meet improving AM potentials. The developed method was evaluated in four discrete experiments to determine its ability to generate three-dimensional (3D), biomimetic, functional texture data. Variables of the experiments can be summarised as measures of; positions and orientations of geometries (structures) that form textures, and how their forms can graduate between locations within the same textures. It was concluded that the novel CAD method may be effectively used to optimise parts' functionalities, by generating high-fidelity 3D textures on their surfaces, which then may be realised with AM technologies.
