Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.
