Lucas123 writes: University of Buffalo physicians and researchers from two institutes working with 3D printer maker Stratasys have successfully 3D-printed anatomically correct models of patients' vascular systems — from their femoral artery to their brain — in order to test various surgical techniques prior to an actual operation. The new 3D printed models not only precisely replicate blood vessels' geometry, but the texture and tissue tension, allowing surgeons a realistic preoperative experience when using catheterization techniques. The printed models are also being used by physicians in training.
