Applications of 3D printing to various anatomies in the field of medicine should start with looking at where we would like to be. Alvin Toffler who died a few years ago defined knowledge-based production as a key factor for the third wave. Furthermore, he stated that prosumers based on actionable knowledge had been a primary resource. Prosumer is a compound word made up with the words of producer and consumer, which means that consumers have to engage in manufacturing application of more valuable technology to improve production speed, range of technology, and the quality (1). These things could fit the medical field better than other industries because 3D printing technology is suitable for a patient-specific and small quantity production (2).
