3D bioprinting is a technique that uses 3D printing and viable living cells to print tissue for medical use, such as reconstructive surgery. It works by collecting cells and turning them into "bioink" which is then printed, layer by layer, with hydrogel, to build tissue. Advantages include replacing human tissue without transplants and higher survival rates of printed cells. Disadvantages include ensuring the printed cells properly fit in the body and the complexity of printing complicated tissues. Applications include creating living organs for transplants, testing new drugs on printed cells rather than animals, and direct printing of cells onto the human body.

7. APPLICATIONS
 Medical industry
 Bioprinting
 Aerospace & aviation
 Automotive
 Industrial 3D printing
 Personal use

8. BIOPRINTING
 Bio-printing technology is developed by Gabor Forgacs, a
biophysicist from University of Missouri in the US
 Prints 3D structure using “bioink” & “biopaper”

9. COMPONENTS OF
BIOPRINTING
 Organ is cut & cells are collected
 Cells are collected & made into “bioink”
 Spheriods are dropped into hydrogel
 Process is repeated till tissue building is complete

10. ADVANTAGES &
DISADVANTAGES
ADVANTAGES
 Replace human tissue
by full body
transplant
 Allows scientists to
eliminate the wait list
of organ transplants ·
 Higher survival rate of
printed cells
 Offers high precise
resolution
DISADVANTAGES
 The replaced cell not sure
to fit in human body
 Large-scale construction
increases the complexity
 Printing capabilities of
complicated tissues
 The necessary
specifications required for
given printing construction
(for therapy design, need
to be precise and specific)

11. APPLICATIONS
 It could be utilized to create entire living organs such as heart, liver
and kidneys
 Creation of functional human beings, which can be printed on
demand and reach maturity in few weeks.
 Newly developed drugs can be tested out on manufactured cells
than on animals and humans. It will lead to a huge reduction in cost
and time.
 Situ bio printing works by imprinting cells directly onto human
body.
