A new method is able to create realistic models of the human heart, which could vastly improve how surgeons train for complex procedures.
- 3D bioprinting involves using printers loaded with biocompatible materials to manufacture living or lifelike structures.
- In a recent paper, a team of engineers from Carnegie Mellon University's College of Engineering developed a new way to 3D bioprint a realistic model of the human heart.
- The model is flexible and strong enough to be sutured, meaning it could improve the ways surgeons train for cardiac surgeries.
Modeling incorporates imaging data into the final 3D printed object.

If scientists can print functional human hearts, it could help the healthcare industry finally meet the demand for heart transplants, which <a href="https://nyulangone.org/news/nyu-langone-addresses-demand-heart-transplants-has-never-been-higher#:~:text=the%20Transplant%20Institute.-,The%20demand%20for%20heart%20transplants%20has%20never%20been%20higher.,rise%20by%20some%2050%20percent." target="_blank">far exceeds supply</a>.</p><p style="margin-left: 20px;">"While major hurdles still exist in bioprinting a full-sized functional human heart, we are proud to help establish its foundational groundwork using the FRESH platform while showing immediate applications for realistic surgical simulation," said Eman Mirdamadi, lead author on the paper, in a statement.</p><p>In the meantime, the team behind the FRESH technique hopes to use it to generate models for other organs, like kidneys and liver. </p>
Rather than one layer at a time, this method creates an entire object all at once, using lasers.
Imagine this, you see something online you just have to have, like a rugged smartphone case emblazoned with your favorite character. You order it and instead of waiting for it to be delivered, your 3D printer fashions it for you, to your exact specifications, in seconds. Why don’t we have this right now? 3D printers can take hours or even days to create an object, making such a scenario difficult to implement.
