Advances in Field-Assisted 3D Printing of Bio-Inspired Composites: From Bioprototyping to Manufacturing

Biocomposite systems evolve to superior structural strategies in adapting to their living environments, using limited materials to form functionality superior to their inherent properties. The synergy of physical-field and 3D printing technologies creates unprecedented opportunities that overcome the limitations of traditional manufacturing methods and enable the precise replication of bio-enhanced structures. Here, we provide an overview of typical structural designs in biocomposite systems, their functions and properties, and highlight the recent advances in bio-inspired composites using mechanical, electrical, magnetic, and ultrasound -field-assisted 3D printing techniques. Finally, in order to realize the preparation of bionic functional devices and equipment with more superior functions, we here provide an outlook on the development of field-assisted 3D printing technology from three aspects: materials, technology and post-processing.
