Polymers used for light-based 3D printing are very stable because of their chemical structure, but they are typically hard to recycle. A research team led by Professor Dr. Eva Blasco, a researcher at the Institute for Molecular Systems Engineering and Advanced Materials (IMSEAM) at Heidelberg University, has designed a polymer material that can be disassembled into its individual components when needed.
