3D bioprinting of soft tissue involves using specialized 3D printers that can deposit bio-inks, or living cell suspensions, in precise patterns and layers to create tissues. Soft tissues successfully bio-printed include skin, cartilage, and even parts of the heart.
One of the advantages of 3D printing soft tissue is the potential for customized and precise fabrication. Using patient-specific cells and biomaterials, 3D-printed soft tissue may mimic natural tissues better and improve patient outcomes regarding functionality and bodily integration.
Another advantage is the potential to reduce the need for donor tissues and organs, often in short supply. With 3D bioprinting, tissues and organs can be created on demand, which could significantly improve the availability of life-saving transplants.
However, some challenges need to be addressed. For example, developing bio-inks that can withstand the stresses of the printing process while maintaining cell viability and function can be difficult. There are also regulatory and ethical considerations, particularly around the safety and efficacy of 3D-printed tissues and organs.
Overall, the 3D printing of soft tissue holds great promise for the future of medicine and healthcare. However, much research and development is still needed before it can be widely implemented.
As mentioned by 3D Systems and CollPlant, their ´aim is to provide breast cancer advanced treatments involving evolving reconstructive procedures to increase the chances of survival by 90% or more. The bioprinted soft tissue matrices will be developed using plant-derived rhCollagen, which does not induce any adverse immune response in the human body and promotes tissue regeneration.´
