It looks like the human mind. It feels like the human mind. This is the “first full-size 3D bioprinted human heart model” and can change the way surgeons treat and prepare patients.

The innovation came from a team of researchers led by a biomedical engineer at Carnegie Mellon University. Adam fineberg.. The model is created using the innovative free-form reversible embedding (fresh) 3D printing technology of floating hydrogel.

“In fresh 3D printing, needles are used to inject bioink into a soft hydrogel bath, which supports the object during printing.” Carnegie Mellon University said in a statement on Wednesday. The hydrogel is then heated, leaving the model.

team is Papers on ACS Biomaterials Science and Engineering Models journal. The American Chemical Society has released a video showing how the heart and the fresh process work.

The new Heart improves and makes our previous efforts on 3D printed models more realistic, thanks to the flexible yet robust alginate material. Alginate is derived from seaweed. “For surgeons, this allows them to create models that can be cut, sutured, and manipulated in the same way as a real heart,” says the university.

Several significant advances have been made in 3D printing for the medical field: A small heart made from real human tissue And wild 3D printed lung air sac Revealed in 2019.

The fresh model is a step towards a bigger dream of printing replacement organs.

“There are still major hurdles to bioprinting a full-sized, functional human heart.” Lead author Eman Mildamadi said“We are proud to be able to establish a basic foundation using the Fresh platform while demonstrating an immediate application of realistic surgical simulation.”
