Text of Abstract
Embedded 3D printing enables the fabrication of soft, intricate biological structures by extruding a liquid filament into a yield stress support matrix. This approach enables the creation of features that exceed the resolution limits of conventional 3D printing. Here, a soft fiber structure approximately 100 µm in diameter, illuminated under ultraviolet light, demonstrates the technique’s precision and stability. The aqueous microgel suspension supports both immobilizing the printed filament and permits in situ polymerization, producing mechanically stable architectures. This method facilitates the replication of complex biological forms such as spider webs and hagfish slime threads and informs the design of advanced biomimetic materials with improved structural fidelity and functional performance.
