Hailey Dawson, a 7-year old girl from Las Vegas was born with Poland syndrome, a rare birth defect that resulted in her being born without the three middle fingers on her right hand. Her mother was determined to help her, and soon she received a variation of Flexi Hand 2, a 3D Printed Prosthetic Hand from University of Nevada, Las Vegas (UNLV). As her story went viral, she has now been invited to throw the first pitch of World Series Game.
One roadblock to 3D printing complete, functional organs lies in our inability to ensure the engineered tissue will be well nourished with an accessible blood supply. Presently we have seen attempts at recreating arteries and veins, but successfully ensuring blood flow deep into tissue to the level of the capillary beds has proven elusive. A group of bioengineers and clinicians have pioneered a technique allowing them to print a fibrin patch containing organized endothelial cells, the cellular linining of blood vessels. Not only did the printed patch enhance blood vessel formation, but the engineered vascular tissue actually integrated with the host's own vasculature, improving tissue perfusion of damaged tissues. This research provides a novel technique that may permit printing of larger blocks of tissue and even organs.
The face of an ancient female Egyptian mummy has been reconstructed with the help of 3D printing and forensic science techniques, an important step to better understand who she was. This reconstruction was only made possible due to the work of a multi-disciplinary team led by scientists at Melbourne University, combining medical research, forensic science, computerised tomographic (CT) scanning, 3D printing, Egyptology and art.
Two professors at Northwestern’s McCormick School of Engineering, Guillermo Ameer and Cheng Sun, have developed a method of 3D printing patient-specific vascular stents that are both flexible and biodegradable. These 3D printed stents can be pre-loaded with drugs that are released at site of implant, shortening the healing process in the walls of blood vessels. Meanwhile the unique polymer material allows the stent to exercise its mechanical function during the vessel’s initial dilation but slowly dissolve as the re-opened blood vessel recovers.
A 3D printed claw to explore Mars has been created by scientists ... inspired by the humble sea urchin's teeth. The device could be used to sample rocks from the Red Planet and other mysterious world's thanks to the spiny creature's extraordinary mouth.
Anecdotal evidence had suggested that high-impact activities, such as roller coaster riding or bungee jumping, could result in spontaneous passage of kidney stones, however 3D printing has now been used to validate the efficacy of a trip to Magic Mountain next time you suffer from kidney stones. A study was conducted at Michigan State University College of Osteopathic Medicine where Dr. David D. Wartinger performed research on whether roller coaster rides can actually facilitate kidney stone passage. A 3D replica of a patient’s kidney was printed in clear silicone material and then was monitored with ureteroscopy during a roller coaster ride. The results verified that roller coaster rides can assist kidney stone passage.
Researchers team led by Ramille Shah at Northwestern University, Illinois, have made progress towards a new type of bone called as the HyperElastic Bone which will be a breakthrough in modern medicine. Using bioactive hydroxyapatite, different biomaterials and EnvisionTEC 3D-Bioplotter System for 3D Printing, this new bone will provide extreme benefits to surgeons.
AMBER Materials Science Center, Ireland, are working on bone grafts through 3D Printing, either via autografting or allografting by inserting the bioprinted materials and patient's stem cells subcutaneously and regenerating the bone. Funded by Science Foundation, Ireland and hosted at Trinity College, Dublin; this new method will provide less painful, successful and affordable reach to the patients with Cancerous tumors or suffering bone defects.
3D Bioprinting is being used in laboratories to produce hearts, livers, kidneys, etc. and no doubt, will be printed in reality for organ transplantation in real patients. But this on the other side, has increased the risk of black market and the ways bad guys will be utilizing these 3D Printed Organs. Since these organs will be available for normal people easily, criminals will find ways to make it not so.
