Abstract
AbstractThe application of reversible deactivation radical polymerization techniques in 3D printing is emerging as a powerful method to build “living” polymer networks, which can be easily postmodified with various functionalities. However, the building speed of these systems is still limited compared to commercial systems. Herein, a digital light processing (DLP)‐based 3D printing system via photoinduced free radical‐promoted cationic reversible addition‐fragmentation chain transfer polymerization of vinyl ethers, which can build “living” objects by a commercial DLP 3D printer at a relatively fast building speed (12.99 cm h−1), is reported. The polymerization behavior and printing conditions are studied in detail. The livingness of the printed objects is demonstrated by spatially controlled postmodification with a fluorescent monomer.
