5 Human Body Parts that can be made with 3-D Printers

3d printing

3-D printers will fade away the concept of donors for human body part replacement.It will evade the concept of long queues of waiting for donors to be willing to donate their parts to the needful.

All it needs is to gear up with results between people practically.Finally, the dream will become a vision for so many scientists.


3D printing was introduced in 1980.Then it was for industries, now for medical science.Researchers have been successful in using the 3D printing technology for healthcare and biological applications.

From custom prosthetics to living tissue 3-D printing will gradually become a cost-effective and individualized care for patients.

The gift of 3-D bioprinting is that cells can now be dispensed from the printer onto a biologically compatible scaffolding, layer by layer.

This will create a three-dimensional viable tissue.Numerous such tissues have to be constructed.

These tissues can now be used for a number of clinical applications from transplants to scientific research.

Nevertheless,  3-D bioprinting is still a relatively new technology. No doubt with time the technology will develop and deliver unchallenged results.

As of now, we highlight only five noteworthy advances in 3-D bioprinting which can revolutionize the healthcare industry.These 5 Human Body Parts are: 

  1. Blood vessels:

One of the biggest challenge or limitations to building artificial organs for implants has been the lack of vascularization (the ability to transport blood and other materials through blood vessels to individual cells)vital to maintaining organ health.

According to Research: A Harvard team has developed a method for creating hollow channels.These hollow channels allow the blood to flow throughout the organ, essentially functioning as blood vessels.

This new development will allow researchers to build thicker, more complex tissues that would otherwise fail.

  1. Heart Valve:

Henry Ford Innovation Institute  Physicians have been using non-bio 3-D printing to recreate hearts and valves.

While there is no actual replacement of organs. Yet the exact replicas of individual organs are invaluable for the optimal treatment of patients.

We all know, each one of us has unique sets of fingerprints. What is a lesser-known fact is that we all have different hearts and valves as well?

How advanced medical science and technology have become, and how they are going hand in hand for humanity can very well be seen by the efforts of these doctors.

The models generated by the 3-D printers allow the doctor to examine in detail the innermost workings of the heart without making a single incision.

This means the helping doctors determine a candidate’s suitability for high-risk procedures as well as optimal placement and custom fit of prosthetic valves. The helping doctors also anticipate adjustments that may be needed once the surgery begins.

And while the 3-D printed coronary facsimiles have already helped dozens of patients, actually making 3-D bioprinted heart valves stands to help even more.

Dr. Jonathan Butcher at Cornell University is developing a valve, made from living tissue as a means of treating aortic valve disease (AVD) and other congenital heart defects.

What is the most remarkable development is that this printed heart valve has the ability to grow with the patient, which other non-living prosthetics lack.

  1. Skin:

A skin gun has been developed that sprays burn victims with their own epithelial stem cells to treat severe burns. However, the technology lacks the ability to treat deep burns very effectively.

Demonstrations for the effectiveness of using 3-D bioprinting for the treatment of deep burns by utilizing multiple skin layers sprayed directly onto the burn site.


  1. Liver cells:

The first 3-D bioprinted liver tissue developer Organovo has shown marked potential to revolutionize medical research.

They are making live human liver tissue commercially available.

The Research Team are now able to test the effectiveness and toxicity of medication prior to clinical trials.That too without the possibility of damaging the liver of subjects.

This will not only reduce the time and cost of research, but the 3-D tissue will also provide vital information to the researchers that normal 2-D models lack.

Michael Renard, executive vice president at Organovo said, quote:

“This gives researchers the kind of tool that they just haven’t had in the past. They can’t do the kind of experiments on a person that they can do with this tissue in a lab setting”.

5. Bionic ear: 

3-D bioprinted bionic ears are currently a viable option.

Cartilaginous tissue (such of the ear) does not need the same level of vascularization as other tissues require.

A team at Princeton has incredibly combined cartilage tissue with electronics in order to create a fully functioning ear. This has some unique capabilities, such as enhanced auditory sensing for radio frequency reception.


We already have the gift of technology to 3-D print prosthetic limbs.

What we are hoping for next is that:

  • One day we will be able to create a customized new limb of living tissue.
  • Post-mortem liver donation becomes a thing of the past.

The future looks brighter and brighter each and every day.We just need to be alive to watch these miracles.
