How 3D Printing Can Help Mend a Broken Heart

  How 3D Printing Can Help Mend a Broken Heart No, this isn't another silly love song; new technology may help transform cardiology.These interventions have vastly improved survival rates, but they don’t heal the damage caused by a cardiac event. The heart is really just one big muscle, and trauma to any muscle does some damage, which becomes scar tissue. Scar tissue on the heart means it functions far less optimally, which eventually leads to heart failure.

Only with 3 D printing of this type can we achieve one micron resolution needed to mimic structures of native heart tissue. “We were quite surprised by how well it worked given the complexity of the heart ,” Ogle said.

David gave me a fascinating insight into his work, including how 3 D printed models of patient’s hearts can help surgeons. How to mend a broken heart display, showcasing how innovations in surgery are allowing us to live longer than ever before.

  How 3D Printing Can Help Mend a Broken Heart © Provided by IBT Media Each year, more than 700,000 people suffer myocardial infarction, aka a heart attack. Thanks to medical advances, there are myriad ways for a doctor to get the blood properly pumping and save a person’s life. A cardiologist might give a patient medication to clear or loosen blockages. Or a doctor might insert a catheter to remove the clot, or place stents in the artery so it stays open.

GE is working on a massive 3D printer for jet engine parts

  GE is working on a massive 3D printer for jet engine parts The company reveals plans for the 'world's largest' 3D printer that uses metal powders.GE Additive is a new business under the larger GE umbrella. It is developing what it calls "the world's largest laser-powered 3D printer" to create parts that fit within one cubic meter cubic of space. "The machine will 3D print aviation parts suitable for making jet engine structural components and parts for single-aisle aircraft," said GE Additive's Mohammad Ehteshami in a statement. "It will also be applicable for manufacturers in the automotive, power, and oil and gas industries.

Short of a transplant, there isn’t a long-term option to fix a damaged ticker. But a team of researchers say they’ve come up with a high-tech solution that could revolutionize cardiology. Using 3-D printing technology, Brenda Ogle, an associate professor of biomedical engineering at the University of Minnesota-Twin Cities, has created a patch a doctor could apply to mend a patient’s broken heart.

“The concept is to imprint proteins that are native to the body,” says Ogle. “We’ve used stem cell–derived cardiac muscle—cardiac myocytes—and actually mixed those with other cell types needed for blood vessels.” This, she says, prevents what would otherwise happen naturally: The formation of a different type cells known as fibroblasts, which secrete scar tissue.

A 3D-printed bridge is being built using reinforced concrete

Manufacturing of the concrete parts has begun, and it's anticipated that bridge construction will start in September. To get to the point where the 3D printed parts were considered reliable, the team at the university first built a 1:2 scale model, which was able to hold a 2,000kg (over 4,400 pounds) load.

Ogle and her team of 3-D printing experts, clinical cardiologists and stem cell engineers have successfully tried the patch on mice. First, the team induced cardiac arrest in the rodents. When they then placed the cell patch on a mouse, researchers saw a significant increase in the functional capacity of the organ after just four weeks. “We generated the continuous electric signal across the patch, and we can pace it: We can increase the frequency of beating up to three hertz, which is similar to a mouse heart,” says Ogle who, this past January, published the findings of their experiment in Circulation Research, a journal from the American Heart Association.

The results of the experiment were so inspiring that in June 2016 the National Institutes of Health awarded her team a grant of more than $3 million, so they can now give pigs heart attacks and fix them with the patch. However, it will take some time to see their innovation in surgical departments, since using biological products such as cells requires a long regulatory process and, of course, quality assurance.

Chrome OS is ready to use printers without the cloud

  Chrome OS is ready to use printers without the cloud Despite decades of attempts to straighten out the connections between printers and computers, it's a situation that always (at least for me) seems to have an extra complication. That's because it has a new ability for "Native Printing," which basically means that it can connect directly to compatible printers on your network, without the need for any cloud connection at all. Some manufacturers and third parties have been getting around the cloud print requirement with extensions like this one, but now support is built in and available to everyone.
