Researchers Develop Nanohybrid 3D-Printed Scaffolds with Stiffness Memory for Tissue Replacement

(3DPrint.com) Tissue engineers combine living cells with scaffolds, 3D printed or otherwise, to fabricate a self-sustaining tissue replacement. Today, 3D printed medical implants are typically stiffer and stronger than the surrounding tissue.
Scientists are researching the use of materials that are responsive to stimuli, to print dynamic 3D structures that can transform their shapes or behavior – like stiffness. A collaborative team of researchers from University College London, Brunel University London, and the Royal Free London NHS Foundation Trust have developed thermoresponsive poly(urea-urethane) (PUU) nanohybrid scaffolds, with stiffness memory, using a 3D printing-guided, thermally induced phase separation (3D-TIPS) method.
