New Breakthrough in 3D Printing: Conductive TPU-Based Scaffolds forMusculoskeletal and Neural Tissue Engineering

Granada, Spain – August 8, 2024 – REGEMAT 3D continues to push boundaries in the field of
regenerative medicine with its latest development: conductive TPU-based scaffolds. These are going
to open modern materials for great strides in musculoskeletal and neural tissue engineering.
Conductive thermoplastic polyurethane, for the first time, provides some peculiar advantages in tissue
engineering applications: its elastomeric features allow high deformation under tensile stress without
breaking; for this reason, it is a perfect candidate in the fabrication of resistant but flexible structures.
In particular, TPU shows reduced electrical resistivity compared with other biomaterials, improving its
potential use in applications requiring the use of electroconductive materials and, at the same time,
ensuring biocompatibility, a very important issue for good integration in tissue regeneration.
REGEMAT 3D has developed a methodology for 3D printing of flexible, electroconductive TPU-based
scaffolds, which are further surface-activated by plasma treatment. This novel process is followed by
coating with poly-L-lysine, enabling the effective culturing of rat astrocytes-a key step that moves
neural tissue regeneration forward.
This breakthrough protocol brings exciting possibilities to researchers and innovators working on
cutting-edge therapies in musculoskeletal and neural regeneration.
