Integrating biology and 3-D printing technologyis 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

What is 3D printing technology?

How Does Organ printer Work?

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

Process

Pre-bio printing

Bio printing

Post-bio printing

3D bio printing generally follows three steps

7

Pre-bio printingPre-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)

Bio printing

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

Post-bio printingThe 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

10

Difficult to create blood vessels between tissue layers,Organs have many specialized functions difficult to replicate

Why Doesn’t Bio printing Work?

11

Benefits 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

Disadvantages

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

The FutureAdvancements in tissue engineering and 3-D

printing technology will help in development of artificial organs from organ printing

-If achieved, more lives could saved and prolonged

Conclusion3D bio printing technology could revolutionize and re-

shape the world. It can significantly change and improve the way we manufacture the products and produce

biological goods all around the globe.
