Despite the very high ability of the human body to repair itself, sometimes factors such as aging or some inherent deficiencies can reduce this ability to a very large extent. Today, with the increasing progress of science in the field of tissue engineering, and technology in the field (Bio printing), it is possible to repair and regenerate damaged tissue or organs. In this regard, the emerging technology (Bio printing) or 3D bio-printing with the aim of producing artificial organs as similar as possible to the natural organs of the human body has taken a fundamental step in the evolution of human life.
What is Bio3dprinting?
Bio3dprinting, or “3D bio printing,” is a technique that uses “bio-inks” to create structures such as living tissue. With the help of bio printers, artificial human tissues or even a complete organ can be produced. 3D printing technology by combining cells, growth factors, and biological materials with the goal of producing tissue or biological organisms that miraculously mimic natural tissue behaviors is called “3D bio-printing.” To start 3D bio-printing, a bio-3D printer is needed, and the “cartridges” of this printer are filled with living cells as raw material. These 3D bioprinters, despite their diversity, have one basic principle in common, and that is the layering of materials on top of each other to produce the final 3D product.
۳D bio printing steps:
The bio printing technique basically includes preparation, printing, maturation and application, which can be summarized in three main steps:
- Before Bio Printing Pre-bio printing: involves creating a digital model that the printer will produce, using the technologies used in CT and MRI.
- ۲٫ Bio printing Bio printing: The printing process is real; Where (Bioink) or bio-ink is placed in the printer cartridge and according to the digital model, layering is done.
- After bio printing Post-bio printing: It is done by mechanical and chemical stimulation of printed parts in order to create stable structures for biological materials.
