Printability Optimization of Gelatin-Alginate Bioinks by Cellulose Nanofiber Modification for Potential Meniscus Bioprinting

Figure 4

3D reconstruction from MRI images and 3D printing process of a patient’s specific medial meniscus. (a–c) MRI data gathered from a healthy volunteer were processed to identify the structure of medial meniscus. (d) A 3D model was then reconstructed and converted to STL file. (e) The STL model was imported into the slicing software to calculate the printing route and a G-code file was generated. (f) Bioink-based, cell-free meniscal prototype was then 3D printed basing on the G-code file.
