The results show that the 3D bioprinter could be developed into an endoscopic tool for endoscopic submucosal dissection procedures. The researchers also conducted various functions like washing, marking, and dissecting the intestine of a pig to test the device as an all-purpose tool for endoscopic surgery. Do state, "We saw the cells grow every day and increase by four times on day seven, the last day of the experiment." This was followed by further tests and experiments that resulted in printing various shapes with nonliving materials on the surface of a pig's kidney and situ living biomaterials on a glass surface inside an artificial colon. IEEE Spectrum reported that the team of researchers conducted the tool's first lab test using non-biomaterials like liquid silicone and chocolate for it prints different multilayer 3D patterns in the lab. Student Mai Thanh Thai both hope that this new method could be an all-in-one tool for avoiding invasive operations, meaning that the tool can be used for incising, cleaning, and printing.Īlso Read: Using Holograms, Sound Fields to Mold 3D Shapes May Be Alternative To Bioprinting, Rapid Prototyping Conducting Lab Tests The researchers, led by the University of New South Wales Graduate School of Biomedical Engineering Than Nho Do and Ph.D. As per Engadget, it also uses three soft-fabric-bellow actuators through a hydraulic system of DC-power-driven syringes, which can move in three degrees of freedom. The 3D bioprinter can spray water onto the target area with a printing nozzle that can double as an electric scalpel. F3DB, the printer's name, features a soft robotic arm that can assemble biomaterials with living cells onto the damaged internal organs of tissues, which will enter the body through the mouth or anus with guidance from the surgeon through a built-in camera. This method would only be minimally invasive to avoid major surgeries and the potential of organ removal.
