![]() ![]() Eman Mirdamadi, Adam Feinberg and colleagues recently developed a technique, called freeform reversible embedding of suspended hydrogels (FRESH), which involves 3D printing soft biomaterials within a gelatin bath to support delicate structures that would otherwise collapse in air. And soft, tissue-like materials, such as silicone rubbers, often collapse when 3D printed in air, making it difficult to reproduce large, complex structures. ![]() Current 3D printing techniques have been used to make full-size organ models, but the materials generally don’t replicate the feel or mechanical properties of natural tissue. For complex heart surgeries, having a chance to plan and practice on a realistic model could help surgeons anticipate problems, leading to more successful outcomes. ![]()
