Technology is improving day by day at a very faster rate. The plug and play human organs is now possible with this 3D printer.
Researchers at Wake Forest University in North Carolina say they have created a 3D printer that can produce organs, tissues, and bones that could theoretically be implanted into living humans. The group’s work was published in the scientific journal Nature Biotechnology.
According to the paper, the researchers’ printer acts much like most 3D printers do, using a computer-controlled nozzle to extrude layers of materials in a very precise pattern. The layers eventually harden to produce whatever you’re trying to print. But unlike with most printers, which put down layers of molten plastic or metal, Wake Forest’s printer lays down what are called hydrogels-water-based solutions containing human cells. The university’s printer has multiple nozzles, some extruding hydrogels, others biodegradable materials that are used to give the tissue it’s printing structure and strength. When the supporting materials dissolve and tissue finishes incubating in the machine, it could be potentially implanted into a person.
The researchers ran three-dimensional scans on human ears, jawbones and muscles to create digital templates for their printer. They then printed out an ear-shaped piece of cartilage, a muscle, and a piece of a jawbone, and implanted them in mice. The structure of the university’s printer allows it to print out tissues that can accommodate blood vessels, meaning they can receive the oxygen and nutrients that cells need to survive. This has been a sticking point for many of the 3D printers that have tried to print living tissue in the past. According to the paper, the school’s printed products showed no signs of necrosis, or cells dying in the tissue.
Can you believe it ? because I cannot. I’m literally struct at the fact that humans will no longer die due to diseases or have a tough life with no organs.
