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

This light - based process is called autostereoscopic bio-printing.The microlens directs the light to the printed surface, and the illuminated area is the 3D object contour that is being printed.At the same time, light triggers the formation of biological chains in various hydrogels, making the gel a solid material.When a 3D object is printed, the reflector array changes the shape of the light pattern to print a new layer.

The process is the first biotechnology to use a variety of materials for automatic stereo lithography, because the traditional stereo lithography technique USES only one type of material.Khademhosseini said the researchers used four types of biological ink, and in their study they said the process could use as much ink as needed.
