The first thing a bioprinter does is read a digital blueprint and then starts to melt a plastic material that is in a roll and pushes the melted plastic through a small nozzle precisely and prints it into the shape of the object in layers in the exact dimensions. And this processes usually takes about 1.5 to 2.5 hours, depending on the size of the print job. Recently, bioprinting has been created, creating exact molds and prosthetics of the patients organs and limbs, creating more organs available for transplant. However, this technolgy is relatively new, and still needs time to become practical.

Bioprinting is better than regular prosthetics because the plastic material that is used to create the hand or arm is very affordable for people and it can get to people in need faster because 3D printers hardly make any mistakes. And if the person designing the arm or leg mess up they will have to restart or even worse if they damage the arm or leg they will have to redo the process again and then the person waiting for that will have to take a extra day or two without receiving the part they need.
