cartilage is a resilient and smooth elastic tissue, a rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.it is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle.
and the new cartilage created by using this method has the same mechanical properties as native cartilage, which is not the case of today's laboratory-grown cartilage. the researchers expect to

unique properties of the joint cartilage attract great attention of engineers and scientists as superior though yet unreachable prototype for material science solutions in designing friction assemblies for machine and robot building as well as for artificial joints.
the knowledge of the topographical variations of articular cartilage material properties is important in terms of the way load is transferred to the subchondral bone because of either altered kinematics or changes in material properties, and even to bone that has suffered some microfracture.
articular cartilage to withstand such high compressive load-ing without being crushed is attributable to the multiphasic nature of the tissue, and the unique combination of the related material properties of the tissue (21,31,35). articular cartilage is vital for maintaining the joint motion, but, when damaged, it is significantly involved in
artificial cartilage is a synthetic material made of hydrogels or polymers that aims to mimic the functional properties of natural cartilage in the human body. tissue engineering principles are used in order to create a non-degradable and biocompatible material that can replace cartilage. while creating a useful synthetic cartilage material, certain challenges need to be overcome.
how 4 universities are using 3d printing to create ears, cartilage and blood cells to native cow cartilage. however, the mechanical properties are inferior to those of natural cartilage
