Major health Crisis Today : Shortage of organs

Solution Create a ORGAN

Heart Valve

Bladder

However, this technology is not using 3D-printing

The concept is :

take a very small piece of that tissue.

Then, grow the cell outside the body.

3D-printing

That is actually a desktop printer, but instead of using ink,

they use cell.

This is a wound. And they are scanning

the wound.

It’s printing the cell onto the wound.

Organ printing Three steps:

1. preprocessing

2. processing

3. postprocessing

1. preprocessing

primarily deals with the development of a computer-aided design (CAD) or blueprint of a specific organ.

The design can be derived from digitized image reconstruction of a natural organ or tissue.

Imaging data can be derived from various modalities including noninvasive scanning of the human body

2. processing

Processing usually refers to actual computer-aided printing or layer-by-layer placement of cells or cell aggregates into a 3D environment using CAD or blueprints.

3. postprocessing

postprocessing is concerned with the perfusion of printed organs and their biomechanical conditioning to both direct and accelerate organ maturation.

Benefit

Shortage of organ donor would likely to be out of equation

the body would have less problem working with the new organ since it's basically made up of your own cell

Recently Research

A group at the German Fraunhofer Institute has created blood vessels, by printing artificial biological molecules with a 3D inkjet printer and zapping them into shape with a laser

In December 2010, Organovo create the first blood vessels to be bio-printed using cells cultured from a single person

Recently Research

In 2011, researchers in Washington State University used a 3D printer to create a bone-like material and structure

Organovo presented its first fully cellular 3-D bioprinted liver tissue data in April at the 2013 Experimental Biology conference in Boston.

Conclusion

The bioprinting revolution could eventually begin to deliver "tissue on demand" within the next 10 or 15 years.

People can lives longer than today.
