In their research, the DITF also work with the Arburg Freeformer 300-3X 3D printer, which can process up to three meltable polymers of different hardness in one component. This enables hard-soft transitions, which are required, for example, in implants for body tissue replacement and in combinations with textiles. The 3D printer processes thermoplastics directly as granules without the detour via printing filaments or powders, so that even very soft or delicate materials can be processed.

One application of additive manufacturing on textiles by applying thermoplastic layers is the production of textile orthoses. Together with the Dynamic Competence Center Claudia Eisert (Mühltal), the DITF are developing a novel foot orthosis with an integrated footbed for patients with cerebral palsy. Unlike previous orthoses made of plastic, this dynamic ankle-foot orthosis consists of a tight-fitting sock that encloses the foot and ankle joint without gaps. The corrected alignment of the foot and depth-sensory feedback enable patients to better perceive the position and movement of their own body.
