3D Printing of Customized Drug Delivery Systems with Controlled Architecture via Reversible Addition‐Fragmentation Chain Transfer Polymerization

3D printing via reversible addition‐fragmentation chain transfer (RAFT) polymerization has been recently developed to expand the scope of technologies. A potentially high‐impact but relatively unexplored opportunity that can be provided by RAFT‐mediated is a pathway toward personalized medicine through manufacturing bespoke drug delivery systems (DDSs). Herein, drug‐eluting with precise geometry, size, dosage, and release duration/profiles reported. This achieved engineering range models interconnected channel‐pore structure geometric proportions in architectural patterns. Notably, application RAFT process crucial materials highly resolved macroscale features confining curing exposure precincts. approach also allows spatiotemporal control loading compositions within different layers scaffolds. The ratio between polyethylene glycol units acrylate crosslinkers found critical factor, higher increasing swelling capacity, thus enhancing profile, from systems. proof‐of‐concept research demonstrates enables production materials, providing replace “one‐size‐fits‐all” traditional health care.
