  • How to look at the first combination of 3D printing and biomedical engineering ?

Technology trends are derived from emerging professions! The current 3D printing technology is the trend of the times, and it has a very broad application prospect in the field of biomedicine. Therefore, it is not surprising that such majors appear in domestic universities. Then, what about the professional support for the faculty, scientific research strength and technical support of the emerging majors in colleges and universities? This requires a ‘topic’ field visit! The following is a brief introduction to the current application of 3D printing technology in the field of biomedicine: 1. What is "biological 3D printing"? Bio-3D printing is based on the principle of “additive manufacturing”, with the special biological “printer” as the means, processing active materials including cells, growth factors, biological materials, etc. as the main content, interdisciplinary aiming to reconstruct human tissues and organs. A new type of regenerative medicine engineering technology across the field. It represents one of the highest levels of current 3D printing technology. 2, "Bio 3D printing" development process and application of the first stage: printed products do not enter the human body, mainly including some medical models, medical devices used in vitro, there is no biocompatibility requirements for the materials used; the second stage The material used has good biocompatibility but cannot be degraded. 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.
