Multi-material vat photopolymerization 3D printing: a review of mechanisms and applications
摘要
Vat photopolymerization (VPP) is originally considered a single-material process due to cumbersome and time-consuming material switching. Multi-material VPP has been continuously explored with significant switching time reductions realized in recent years, enabling rapid, functional device printing. In addition, VPP hybridization has been explored, enabling printed objects comprising of diverse UV-curable and functional materials. Herein, the authors review the current state of multi-material VPP and VPP hybridization and the remaining challenges.
