Researchers have published a new 3D bioprinting method that brings the field of tissue engineering one step closer to being able to 3D print a full-sized, adult human heart.

Science Astounding 3D-printed human heart model cuts and sutures like the real thing The full-size, life-like model could give surgeons a chance to practice their life-saving skills.

Though smaller in size, the 3D-printed organ features the same cellular structure as a full-sized human heart. The company sees this first example as a roadmap toward bioprinting a full-size human ...

In addition, this team hopes to eventually “cellularize” the printed heart, or add human heart muscle cells to the structure, to make it beat like the real thing.

It's not science fiction anymore: 3D-printing a human heart is now a reality. A company called Biolife4D has developed the technology to print human cardiac tissue by collecting blood cells from a ...

American researchers have 3D-bioprinted a miniature human heart, using human cardiac cells.

Miniature-sized heart chambers called ventricles have been 3D printed with live human heart muscle cells and shown to beat on their own for at least three months.

This works well for creating complex tissues like those found in the human heart where the 3D structure is critical to its function. Of course, there are major challenges to this approach, too.

Science Stanford Scientists Use Stem Cells to 3D-Print Heart Tissue The technique could one day lead to organs printed on demand from a patient's own cells.
