Dr. Matthew Bramlet discovered 3D printing back in 2009, and not long after that the pediatric cardiologist was 3D printing his first heart model.

Last year, we updated you on Dr. Bramlet's project, which has since gained several partners and is growing into an open, expanding digital repository called the 3D Heart Library. Now, eight years after he first discovered 3D printing, Dr. Bramlet and several other experts have published a paper on the impact of 3D printing on the treatment of congenital heart disease, appropriately titled "The Impact of Three-Dimensional Printing on the Study and Treatment of Congenital Heart Disease."
