3D printing technology is undoubtedly the hottest topic of manufacturing technology innovation in today's capital market, but its application in the medical field is less concerned. The combination of 3D printing technology and human medical applications is quite high. Recently, Fripp has printed fake eyes, ears and nose.
According to British company Fripp, the dream of printing 150 fake eyes in an hour has become a reality. This large-scale production technology not only accelerates the production speed of the fake eye, but also greatly reduces the production cost. Each eye printed has a slight difference in hue, which is to produce a better aesthetic effect. The goal of this project is to provide patients in developing countries with affordable eyewear.
Fripp also collaborates with the University of Sheffield in the UK to produce facial prostheses such as the ears and nose. After a 3D facial scan of the patient, the prosthesis is printed with pigment, starch, and silicone to replicate the facial structure that closely matches the patient's original nose or ear. The real benefit of this project is that when you start wearing a facial prosthesis, you can order it again with only a small portion of the technology.
Ears made from live cells in a 3D mold. A research team at Cornell University in the United States is working on a different project: printing a 3D mold of a patient's ear using an ink gel containing living cells. The printed product is injected into the collagen of bovine chondrocytes and mice and grown to a finished product after 3 months. The researchers said that humans may start transplanting the prosthesis within three years.
Plastic skull. According to doctors from the Utrecht University Medical Center in the Netherlands, they successfully produced a plastic skull in 3D for the first time, completely replacing a patient's original skull surgery. This patient has a skull thickness of 5 cm due to chronic bone disease, leading to blindness. Three months after the surgery to replace the skull, the patient not only regained the light, but also returned to work.
James You, of the Wake Forest Medical College in the United States, is working on a printer that prints skin directly on the wounds of burn patients. "Ink" consists of enzymes and collagen, which are layered with tissue cells and skin cells to form a transplanted skin. The research team intends to develop a portable printer that can be used directly to print skin on a patient's wound in remote areas and theaters.
Thermoplastics are the leader of artificial hands, arms, and even finger breeding. Richard Van As is one of the producers of these affordable hand and finger prostheses. His company Robohand is headquartered in South Africa. The research team combines thermoplastic polylactide printing with aluminum and stainless steel fingers to create a functional robot.
Robohand is working with American entrepreneur Mike Abelin on a project to provide affordable limbs for people who have been injured by injuries during the Sudanese war. The collaboration, known as the Daniel Project, was named after the 14-year-old Daniel Omar, who fell near his home in the Sultan Nuba Mountains, causing him to lose both palms and parts of his arm.
One of the most mature areas of 3D printing development is the bioprinting of human bone implants, now called replacement bones. In 2011, researchers at Washington State University announced that they had printed a bone-like structure that could serve as a scaffold for new bone cell growth before disintegration. This structure was printed with calcium phosphate and has been successfully tested on animals.
