In recent years, the research and industrialization of biomedical materials and implantable devices has become a hotspot in the medical device industry, and the emergence and application of 3D printing technology has promoted regenerative medicine as a new discipline.
In response to the development of new technologies, such as organ repair, 3D printing has become a paradigm for the convergence of biotechnology and materials technology. First of all, 3D printing technology will be able to overcome the difficulties of tissue damage and organ failure. Each person's own tissues and organs will be readily available, which is equivalent to creating a reservoir system of tissues and organs for each person. Secondly, the level of epidermal repair and cosmetic applications will be further improved.
With improved printing precision and material adaptability, body tissues will be more finely trimmed and fused, helping to create more aesthetically pleasing human features. Finally, as 3D printing equipment becomes more widely available, in some emergency situations, 3D printers can be used to create medical supplies such as catheters and surgical tools, making them more personalized, while reducing access and time, and temporarily solving the problem of a shortage of medical supplies.
Therefore, the future trend of 3D printing technology will be reflected in the increase of 3D printing speed, the development of more diverse 3D printing materials, the miniaturization of 3D printers, the reduction of costs, and the expansion of its application in more industries.
3D printing technology has made many achievements in the preparation of biomedical materials, especially tissue-engineered scaffold materials. However, there are still great challenges to realize the true clinical application of 3D printed biomedical materials.
The research and development of materials restricts the development of 3D printing technology besides, the research and development of biomedical materials suitable for 3D printing will become a future research hotspot. The main reason why the development of 3D printing biomedical materials is difficult is that there are high clinical requirements for the various properties of the materials, the choice of materials is subject to a variety of factors, both before and after the printing of the material safety, biological and chemical properties of the material should be considered. Compatibility, degradability, bio-responsiveness, etc., and whether the material can meet the requirements of industrialization should also be considered.
Future research on 3D printed biomedical materials should focus on developing more printable biomaterials.
