The team printed the hybrid structures on a self-built digital-light processing (DLP)-based multi-material 3-D printer. They facilitated covalent bonding between the AP hydrogel and other polymers through incomplete polymerization initiated by a water-soluble photoinitiator. The team displayed a few applications based on this approach to propose a new way to realize multifunctional soft devices and machines by bonding hydrogel with diverse polymer in 3-D forms.
