Digital fabrication technology presents an unfamiliar territory for textile design,thus requiring exploration and analysis of the emergent forms of textile crafting andmateriality. Through practice-based research methodology, this research examines the intersection of two fabrication methods: industrial knitting and 3D filament printing, with the aim of outlining a hybrid material territory for 3D textile composites. Accordingly, the research addresses the notion of textile as a multi-material system. The physical results are presented as a material library of samples which have been produced through two methods: i) the exploration of geometric tessellations to generate self-folding surfaces by direct printing on non-elastic knitted structures; ii) the exploration of pattern arrays to generate self-forming surfaces by direct printing on pre-stressed knitted structures. Using this hybrid approach to textile crafting the research discusses the aesthetic possibilities of the fusion of these two technologies, and the potential for development within the Industry 4.0 model.
