3D bioprinting uses a layer-by-layer printing process to construct living human tissues and organs by depositing hydrogels, collagen, and cells. Over 6,000 people in the UK are waiting for organ transplants. The technology has the potential to print organs like livers, kidneys, and even hearts to help address the shortage of donor organs. However, 3D bioprinting also raises ethical issues and implanted organs may face rejection by the human body.

Introduction.
3D bio-printing helps constructing living human tissues
and organs
Printing process is made by using printing layer-by-
layer approach to generate desired part of the body .
According to NHS 6,977 people are waiting for
transplants and 616 received transplant.
3D organs liver, kidney, aortic valve or even heart.

Process.
Directed by sofware ;BioInk and cartridge of Hydrogel
are loaded into the 3D bio printer and printed on
biopaper .
Printer prints first layer of the water-based gel,colagen
and second BioInk cells .
Second layer of BioInk cells.
Layers blend together building up the human organs.

Technology.
by Nikesh Patel 5
Organovo NovoGen MMX bioprinter
 Includes 2 print heads:
one for placing human
cells and one for the
hydrogel matrix.
 Can produce blood
vessels, nerves conduit
and organs.

6. 
Advantages
by Nikesh Patel 6
The waiting list for transplant can be reduced
considerably.
Offers high precise resolution scan can be obtain and
software
can calculate the exact size of the desired replacement.(eg
bones)
 Quick process ,10 days to print an average sized liver
and lobe. Time will be reduced considerable as the
technology advances.

7. 
Disadvantages
by Nikesh Patel 7
It will bring a major ethical and moral debate on
its use .
Implanted organ can be rejected as body cant
accept them as functional tissue.
 The cost of printers are very expensive.

Conclusions
by Nikesh Patel 11
 Master course of 3D bio-printing human body parts
launched at Queensland University of Technology in
Australia in may 2014.
 “3D bioprinting facilities with the ability to print human
organs and tissue will advance far faster than general
understanding and acceptance of the ramifications of
this technology," Pete Basiliere
THANK YOU !
