Biomimetic Vascular Scaffold with Seamless Electrospun Aligned Nanofiber Conduit and 3D‐Printed Coil Reinforcement

Advanced Healthcare Materials, EarlyView.
We introduce a new fabrication method that overcomes the current limitation of tubular gap electrospinning. We successfully fabricated a seamless hollow tube with fibers aligned along the longitudinal axis in diameters as small as 300 µm, and then reinforced it using 4‐axis 3D printing.
