3. Integrating biology and 3-D printing technology
is a process where an artificial organ or any three
dimensional object can be created using a 3-D
printer/bio printer
-Currently NO real organ has been successful
created, but scientists are currently working on this
idea and are making progress 3
4. After cells fuse, bio paper is removed
Layers are printed one top of each other
Printer prints out one layer of cells at a time on bio paper, which is made up of collagen,
water, and hydrogels
Printer moves back and forth dropping out one bio ink particle at a time to form one layer
Uses bio ink, mixture of stem cells

7. Pre-bio printing is the
process of creating a model
that the printer will later
create and choosing the
materials that will be used.
One of the first steps is to
obtain a biopsy of the organ.
The common technologies
used for bio printing are
computed tomography (CT)
and magnetic resonance
imaging (MRI)

8. In the second step, the liquid
mixture of cells, matrix, and
nutrients known as Bio inks are
placed in a printer cartridge and
deposited using the patients'
medical scans. When a bio
printed pre-tissue is transferred
to an incubator, this cell-based
pre-tissue matures into a tissue

9. The post-bio printing process is necessary to create a stable
structure from the biological material. If this process is not
well-maintained, the mechanical integrity and function of
the 3D printed object is at risk. To maintain the object, both
mechanical and chemical stimulations are needed

11. 11
Artificial organ personalized using patients own cells
No DNA rejection
Eliminate need for immunosuppressant drugs
needed after a regular organ transplant
Eliminate organ donation
No waiting period
12. 12
Printers cost hundreds of thousands of dollars
Possibly more expensive than regular organ transplant
Use of stem cells is still controversial
Cost of using stem cells
Not successfully created yet
