News Context: However, once these thermosetting photopolymers form 3D parts through UV curing triggered chemical reaction, the covalent networks are permanent and cannot be reprocessed, i.e., reshaped, repaired, or recycled. This attribute improves printing efficiency as, for instance, 3D origami parts can be generated from flat, 2D layers. Secondly, the structure is repairable, meaning that damaged sites can be reprinted while perfectly maintaining structural integrity, prolonging product durability.

These 3DPRTs provide a practical solution to address environmental challenges associated with the rapid increase in consumption of 3D printing materials. Compatibility with UV curing-based 3D printing makes thermosetting photopolymers ideal for printing high-resolution structures at micro-scales , submicro-scales , and even nano-scales [1] .
