The increasing gap in the demand and supply of organs puts the lives of end organ failure patients under extreme risk. Hence any ability to generate organs in the lab would come as a big relief. Bioprinting is a growing technique with promising success in the printing of simple 2D organs as well as initial partial successes in printing of complex tissues like lungs, heart valves etc. It is also useful in many other applications like drug testing, tumor studies etc. However the technique still has to overcome many challenges before it can become a dependable process in the clinics and labs.
