Is it possible to print a beating heart?

July 16, 2020 — In a groundbreaking new study, researchers at the University of Minnesota have 3-D printed a functioning centimeter-scale human heart pump in the lab.

Can you print a 3D heart?

Adam Feinberg and his team have created the first full-size 3D bioprinted human heart model using their Freeform Reversible Embedding of Suspended Hydrogels (FRESH) technique. The model, created from MRI data using a specially built 3D printer, realistically mimics the elasticity of cardiac tissue and sutures.

How long does it take to 3D print a heart?

A team of researchers from Tel-Aviv University (TAU) successfully 3D printed a heart using human cells back in April 2019. Researchers estimate that it will take an additional 10 to 15 years before this solution is viable. Therefore, researchers at the University of Minnesota flipped the process.

What are 3D printed prosthetics?

After 3D scanning the wearer’s residual limb, a prosthetic design is made in 3D modeling software, after which both the hand and its socket are 3D printed. As all the mechanical components of the hand can be 3D printed, it becomes a cost-effective alternative to the traditional, expensive prosthetic.

How do they 3D print a heart?

They begin with a scan of a real heart and translate the data into something a 3D printer can read. But instead of it extruding it into air, as a normal 3D printer might do when building something out of plastic, this extrudes the ersatz heart into a container of support gel, specifically gelatin.

What is medical 3D printing?

3D printers are used to manufacture a variety of medical devices, including those with complex geometry or features that match a patient’s unique anatomy. Other devices, called patient-matched or patient-specific devices, are created from a specific patient’s imaging data.

What is a 3D heart called?

A 3D heart ultrasound, also known as a 3D echocardiogram, is a diagnostic test that creates 3D videos of the heart. This simple, painless test uses an ultrasound probe and gel on the skin of the chest. Ultrasound can reveal the size and function of the heart’s chambers and valves.

How is 3D printing being used in the medical field?

3D printing in medicine can be used to print organ models. These could also be helpful for patient education and pre-operative planning for surgeons. Just recently, scientists are using a combination of MRI and ultrasound imaging along with 3D-printing technology to help doctors prepare for fetal surgeries.

Is 3D printing used for prosthetics?

Scientists from the Israel Institute of Technology have developed an automated production line for 3D printing low-cost customized prosthetic limbs. Within the team’s streamlined design process, amputees’ unaffected hands are scanned, tailored using CAD software and converted straight into an STL file ready to print.
