DESIGN AND 3D PRINTING OF KNEE JOINT

The objective is to study the wear of the knee joint using static structural analysis, degrees of freedom, joint probe and ansys software, and to develop a 3D modeling of the knee joint using CatiaV5. In this manufacturing model, all the bony parts of the human knee joint, such as the femur, tibia, fibula, and patella, are made exactly the same size and have a good surface finish. The bones of this knee joint are made of acrylonitrile butadiene styrene (ABS) and manufactured by a melt deposition modeling (FDM) technique. Design the knee joint model using CatiaV5 software. The 3D model is saved in STL format and transferred to the 3Dreality Slicer. Then the 3D slicer sliced the object layer by layer. The object design is then printed on a 3D printer and the print is overprinted until an accurate model of the natural joint is created. 3D artificial knees, like traditional artificial joints, can be made of metal, plastic, or a combination of the two. Use the FDM method to identify force problems acting between two extremes of a process. It can be seen that by applying an allowable load to the joint, the degree of freedom, wear, and friction load can be controlled.
