Biodegradable elastomers for low‑temperature 3D printing and extrusion
The University of Minnesota offers a biodegradable thermoplastic elastomer technology that can be 3D printed or extruded below 60°C, preserving bioactive payloads and enabling innovative bio-functional packaging.
The University of Minnesota has developed a biodegradable thermoplastic elastomer that can be processed at temperatures below 60°C, which is significantly lower than traditional methods requiring above 100°C. This material combines polycaprolactone (PCL) with stretchable amorphous blocks, resulting in a biodegradable, non-cytotoxic elastomer suitable for low-temperature 3D printing and extrusion. Its ability to preserve bioactive agents during processing opens new possibilities for biomedical implants, bio-functional packaging, and environmentally friendly products. The technology is at TRL 3-4, indicating lab-scale validation, and is available for licensing and co-development.
