Interfacial Regulation for 3D Printing based on Slice‐Based Photopolymerization

Abstract

Abstract3D printing, also known as additive manufacturing, can turn computer‐aided designs into delicate structures directly and on demand by eliminating expensive molds, dies, or lithographic masks. Among the various technical forms, light‐based 3D printing mainly involved the control of polymer‐based matter fabrication and realized a field of manufacturing with high tunability of printing format, speed, and precision. Emerging slice‐ and light‐based 3D‐printing methods have prosperously advanced in recent years but still present challenges to the versatility of printing continuity, printing process, and printing details control. Herein, the field of slice‐ and light‐based 3D printing is discussed and summarized from the view of interfacial regulation strategies to improve the printing continuity, printing process control, and the character of printed results, and several potential strategies to construct complex 3D structures of distinct characteristics with extra external fields, which are favorable for the further improvement and development of 3D printing, are proposed.
