| Summary: | Fused Filament Fabrication (FFF) 3D printing of electrically conductive paths holds promise for implementing smart electronic functionalities on textiles. The ease of design modifications, a high degree of design freedom and the structural functionality of 3D printing make it an attractive technology for the rapidly evolving field of smart textiles which is still being explored for its full potential regarding functionalities. In electronic textiles, the conductivity of conductive tracks needs to remain stable under conditions such as repeated stretching, abrasion or washing. We show the behaviour of conductive materials printed using FFF under repeated strain with a focus on the functional additives used to achieve conductivity. Different carbon based additives, such as carbon black (CB) materials optimized for conductivity and multi-walled carbon nanotubes (MWCNT), as well as short metal fibres are investigated for this purpose. The need for detailed investigation of electrical conductivity after each production stage and during use is explained and effects of printing and repeated strain on materials are discussed. Durability against abrasion and washing under different conditions are tested. |
