Researchers at the Istituto Orthopedico in Rizzoli, Bologna made an attempt to improve on current methods for making tissue repairs and replacement by creating 3D Printed Meniscus Prototype. Using the real MRI Scans and converting them to .stl file, then proceeding to create a model from which to make the meniscus prototype and resulting scaffolds. The researchers used the 3D printed model of the knee to assist in reconstruction of the meniscus. They used a series of 2D cross sections to create tool paths, using LifeInk 200 bio-ink as the material for printing cells, and then 3D Printing the final product of Meniscus Prototype.
