Scottish scientists make 3D stem cell printer

The video discusses the use of a 3D stem cell printer that utilizes two types of bio ink: one containing stem cells and another without. The printer can adjust the size and number of stem cells in droplets, printing them in alternating layers. This technology holds the potential to create new organs for transplant in the future.

Describe the process of how the printer prints the bio inks.

What potential future application of this technology is suggested?
