One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...
