Transcript of 3D Printing In Medicine

Done By: Sarah, Joud,Roa,Diana
What is 3D Printing?
Bioprinting is the 3D printing of biological tissues and organs through the layering of living cells to restore or establish normal function.
It is still in the experimental stage.

The technology was initially founded by Charles w. Hall in the mid 1980s
It is commonly referred to as additive manufacturing or stereolithography
Uses of 3D-Printing:
Engineering tissues and organs for transplant
Developing models for
Education purposes
Research, drug discovery and toxicology (eg. Cancerous tumors)
Print copy of organ in interest to study before performing surgery
Printing drugs- personalised drug library
Prosthetics
Scientists have successfully engineered...
Flat structures
eg. skin
Tubular structures
eg. urine tubes, blood vessels
Hollow structures
eg. bladder

Successful Skull Replacement
At the University Medical Center in Utracht the entire top portion of a 22 year old woman's skull was replaced with a customized printed implant skull tailored for her.


Advantage of this over old method: exact fit and better brain functioning.



3D Printing In Medicine
Examples on uses:
Multilayered skin
Wounds of burn victims
Wound scanned printer fabricates appropriate
number of skin layers
Bone transplant
Perfect fitting
More reliable than current titanium implants
Heart tissue
Heart valve will be tested on sheep at Cornell University
 Ear
Has built-in electronic components for superhuman hearing

Case: printing copies of organs
Morgan Stanley Children's Hospital was able to print out a 3D copy of a two-week-old baby ‘s oddly structured heart,
study it, and develop a detailed surgery strategy to repair the baby's heart with one operation only.

a virtual design is created using 3D
modeling program/3D scanner
and the printer's software "slices" the model into thousands of horizontal layers
First:
Aims for the future:
Engineering transplant organs with no fear of rejection
Easily replaceable parts
Reduce medicine costs
Increased life expectancy

Barriers and Implications
Approval to test on humans
FDA approval of the final product
Religious groups could consider this technology against the will of God
If low competition, prices could be too high
Safety: cannot foresee the safety of each, personalized and thus a case by case situation
May become a business instead of medical resource
