The scientists used four types of biological ink 3D printing tissue, which was implanted in rats without rejection and could be used for cancer research.

Researchers at the university of California, Los Angeles (UCLA) have developed a technology that USES modified 3-d printers to build therapeutic biomaterial.They hope that in the near future, complex skin tissue that needs to be printed on demand can be used for skin grafts or other operations.

Ali Khademhosseini, who led the study at UCLA, said: "the organization is a complex and complex structure, so we have to recreate the complexity in order to design a functioning artificial organization.We provide a way to build complex biocompatible structures by using different materials.

Khademhosseini's 3D printer has two key components.The first is a custom microfluidic chip, a small platform similar to the size of a computer chip that handles liquid flow.It has multiple entrances, each "printing" different materials.The other component is a digital micromirror, a group of more than a million tiny mirrors, each moving independently.
