In addition to many advantages, there is currently a very big disadvantage for use in the textile sector. The filaments available on the market are for the most part too hard/rigid and therefore do not have the desired softness, flexibility or stretchability for a textile application. On the other hand, only a few filaments contain special additives to add additional functionalities such as e.g. flame retardancy, colour, optical effects, abrasion resistance and antimicrobial efficacy.
Functionalized thermoplastic filaments for 3D printing have been developed at the Saxon Textile Research Institute e.V., which are particularly suitable for application to textiles.
