  • The development history and application of "biological 3D printing"

The first stage: the printed products do not enter the human body, mainly including some medical models and medical devices used in vitro, and have no biocompatibility requirements for the materials used; the second stage: the materials used have good biocompatibility However, it cannot be degraded, and the product becomes a permanent implant after being implanted into the human body; the third stage: the material used has good biocompatibility and can be degraded. After the product is implanted into the human body, it can interact with human tissues to promote tissue regeneration. The fourth stage: using living cells, proteins and other extracellular matrices as materials to print bioactive products, the ultimate goal is to create tissue. ,organ.
