New technique can print life-like organ models in minutes NIBIB-funded engineers at the University of Buffalo have fine-tuned the use of stereolithography for 3D printing of organ models that contain live cells. The new technique is capable of printing the models 10-50 times faster than the industry standard-;in minutes instead of hours-; a major step in the quest to create 3D-printed replacement organs. Conventional 3D printing involves the meticulous addition of material to the 3D model with a small needle that produces fine detail but is extremely slow taking six or seven hours to print a model of a human part, such as a hand, for instance. The lengthy process causes cellular stress and injury inhibiting the ability to seed the tissues with live, functioning cells.
