Application case:
Light-cured printing technology can make more tissues and organs. Here are some typical examples.
Soft bones:
In clinical treatment, the repair of cartilage defect is a great challenge. Scientists from the University of Oklahoma and South China University of Technology have developed a new double-layer hydrogel structure, which can effectively repair the defects of bones and cartilage when combined with nano-boxes.
repair in trauma
Researchers from Aubrey College University in Finland and University of Wollongong in Australia used nanofibers and bio-printing ink. Low concentration bio-ink can be printed into a three-dimensional bio-scaffold with stable structure and high precision by crosslinking calcium ions with ultraviolet light. The printing scaffold has no cytotoxicity and biocompatibility to 3T3 fibroblasts, and can promote the proliferation of fibroblasts. This study provides a potential application prospect for wound healing.
cardiac valves
Biological 3d printing technology can produce engineering valves with heterogeneous mechanical properties and anatomically accurate cells. This is an ideal engineering valve, which can grow together with the patient's tissue and can be used as a substitute for living valve for future treatment.
Future prospects
In addition to the above fields, the application industry of light-cured 3d printers also includes the research of neurobiology, blood vessels, skin, corneal tissue and organ chips. It has become an important technology in the process of 3d bio-printing.
