Breakthrough in Artificial Cartilage Production Using 3D Printing

Researchers at TU Wien have developed a novel 3D printing technique for creating artificial cartilage, potentially revolutionizing treatments for joint injuries.

A new high-resolution 3D printing process creates tiny, porous spheres that serve as scaffolds for growing cartilage cells.
The technique allows for the precise shaping of tissue, overcoming previous limitations in controlling tissue geometry.
Cells within the 3D-printed spheres merge seamlessly, forming uniform, living tissue without cavities.
The biodegradable plastic scaffolds provide initial mechanical stability but degrade over time, leaving behind mature tissue.
This method could be adapted for other tissues, like bone, although challenges such as incorporating blood vessels remain.
