I have seen about 3D bio printing related articles, is that technology is proven, or under research ?
Not fully proven as per sources …slowly it is making inroads. Advances in 3-dimensional (3D) printing have increased the feasibility of living tissue synthesis. This technique , known as 3D bioprinting, involves accurate layering of cells, biological scaffolds and growth factors with the goal of producing bioidentical tissue for a variety of uses.
This is the technology that will enable the reproduction of body parts, heart, joints, etc. in the future.
3D bioprinting technology is a viable technique for ophthalmological applications. It provides high sensibility and accuracy which is required in ophthalmological procedures.
