The use of three-dimensional printing is prevalent in many industries, including fashion industry. Three-dimensional printing has come into wide use in different industries including fashion industry. Fashion and textile designers adopt the 3D printing technology as their creative design tool, for example, when creating 3D printed garments, fabrics or fashion accessories. It can be predicted that 3D printing technology will be rapidly applied and it will play an important role in the fashion industry in the future. This research study aimed to develop a theoretical design process model specifically for the creation of a 3D printed fashion prototype with multi-coloured surface texture. By adopting the practice-based research methodology and the developed design process model with reference to the theories of 3D printing technologies, practical concept, physical prototyping techniques and corresponding evaluation of various design elements, an innovative 3D printed fashion prototype was finally produced.
