As The Cell Culture Dish has reported in the past, bioprinting isn’t just about the act of printing out a structure. A successful bioprinting process means that the cells will form higher order structures when given the time and the proper biochemical/environmental cues. As such, it isn’t the printing process that takes the most time. The time it takes also depends on the complexity of the structure, and the size. There is not really a hard answer for this, as so many variables affect this time.
