With the continuous advancement of technology and the expansion of application scenarios, the global 3D printing market is expected to reach a size of 76.17 billion US dollars by 2030. It is expected that the 3D printing market will develop at an astonishing compound annual growth rate of 20.8% from 2022 to 2030, and present increasingly diverse application areas and trends. This number also reflects the widespread recognition and pursuit of 30 printing technology by countries and regions around the world, as well as the enormous market potential.
The application of 3D bioprinting is in three aspects.
Firstly, it is used to manufacture materials that are non biocompatible outside the body, which can be applied to 3D printed medical models, surgical guides, customized orthopedic instruments, etc;
The second is to manufacture biocompatible in vivo implants (including degradable and non degradable materials), such as personalized permanent implants such as metal printed mandibular implants, as well as biodegradable, biomimetic, and tissue-engineered scaffolds that induce tissue regeneration;
The third is to construct biomimetic three-dimensional tissues containing living cells. The organs and tissues such as skin, ovaries, bladder, and heart that have been transplanted into animals now maintain good biocompatibility even after implantation.
In recent years, with the help of 3D bioprinting to simulate the three-dimensional environment required for human tissue growth and the addition of growth factors that induce differentiation, simple bone tissue (skull, mandible, cartilage), neural spinal cord, blood vessels and other substitutes similar to normal human tissues and organs have been cultivated, laying the foundation for the development of regenerative medicine.
