(a) Schematic Illustration of multitechnology biofabrication showing typical operation length of single deposition biofabrication technologies with the size and hierarchical structure of tissues and organs. Adapted from ⁴⁰ (b) Convergence of MEW (PCL) and extrusion-based bioprinting (GelMA) into a single-step approach. (c) Fluorescence staining showing spatial placements of the cells in the composite constructs. (d) The guidance of MEW fibers over a strand of hydrogel for development of complex tissue architectures l) interlocked with hydrogel, and ll) out-of-plane fiber deposition. Yellow arrows depict the hydrogel whereas the white arrows depict the PCL fiber. Scale bar = 500 μm Adapted from.³⁸
