Release date: 2016-04-08 April 6, 2016 Recently, in a research report published in the international magazine Biofabrication , researchers from Australia successfully used a handheld 3D printing pen to successfully draw a higher pattern in free mode. Survival rate of human stem cells. The new device developed by the researchers can help surgeons perform personalized cartilage transplants during surgery. The researchers pointed out that the use of hydrogel-like "bio-ink" to carry and support human stem cell growth, and the use of lower light sources to coagulate "bio-ink", the survival rate of stem cells transported by the pen will exceed 97%. And this new type of 3D printing pen also greatly helps tissue engineering research, for example, it can print out cells layer by layer to build artificial tissue for transplantation. However, in some cases, such as during cartilage repair, the precise geometric properties of the implant may not be accurately applied to the surgical procedure, which makes the preparation of the artificial cartilage tissue graft become Complex and difficult; the new print pen acts like a surgeon's hand, and can accurately fill a missing frame or implant into the missing part of the patient's body. Researcher Professor Choong said that the development of this new type of device is the result of a joint effort between scientists and clinicians, and will bring unprecedented changes to improved research and patient care. The print pen is light, compact, ergonomic and sterilizable, and is also equipped with a lower power source and curing agent; researchers believe that this new device will better help scientists "draw print" later. "The human stem cells are used for clinical research for therapeutic purposes.
