Fused Filament Fabrication over fabrics – experiments and applications

Abstract The focus of this paper is to explore the use Fused Filament Fabrication technology, a material extrusion additive manufacturing by depositing melted Polilactic Acid (PLA) over substrate – fabric - instead on an empty building tray. textile’s composition, nozzle and plate temperature, printed PLA thickness geometry have been considered as variables that could influence structural adhesion properties study so, therefor, were took into consideration tested throughout printing process through specimens with different combined parameters. aim exploration was developing experimental procedure limitations capabilities technology textiles, which variables’ combination would contribute better overall result in development self-supporting textile based model, be apply contexts without need any extra external support. Results showed adherence correlated nozzle/building temperature thickness: higher provide adherence. weave didn´t reflect results but polyester felt exhibit maximum all sets temperatures. In addition, geometries reinforcement lines along stress direction provided results. These enable new application possibilities for FFF fabrics such interior, fashion shoe ware design.
