South Korea has developed a 3D printed medical device silk system
Recently, the Korea Rural Development Authority (RDA) announced the development of a new silk 3D printing system using silk protein as a 3D printing material. It is reported that the system was jointly developed by RDA and Hanlin University in South Korea and can be used to print medical equipment .
As we all know, silk is a natural protein fiber from silkworm cocoons. It has been regarded as a raw material for high-grade textiles - silk since ancient times. Now, researchers at RDA and Hanlin University have found that it can also be a viable 3D biomaterial.
It is reported that silk fibroin is composed of 75% silk fibroin. This protein is often used in the manufacture of medical equipment because of its biocompatible properties. It can be said that it is widely used in the medical field because of biocompatibility. Equipment made of materials is less likely to cause problems in the human body. Recognizing the potential of biocompatible materials and the potential of 3D printing technology to create precise shapes, researchers at RDA and Hanlin University decided to develop a silk 3D printed material for orthopedics such as plates, screws, and clips. Preparation of the implant.
It is reported that these 3D printed instruments are mainly used to insert the patient's body during surgery to help stabilize and support broken bones. They are usually made of stainless steel or titanium alloy materials, but the devices of these metal materials are fully recovered in patients. After that, it needs to be removed again by surgery. If you use silk protein to print in 3D, you can completely biodegrade, and you don't need surgery. This makes the 3D printed silk fibroin device significantly superior to metal products, greatly reducing the possibility of surgical trauma and complications. By optimizing print temperature and nozzle configuration based on 3D bioprinting requirements, researchers were able to create a usable silk printing system to make medical devices.
