3D Printing in Medicine: Custom Prosthetics and Organ Transplants

As is often the case in the realm of medicine, change, and innovation is a good things. And the newcomer in the list is none other than 3D printing which has amazed the medical field. Once applied in manufacturing, specifically in the creation of prototypes, imaginative 3D printing belongs nowadays to hospitals and research labs. A limb or a doll in the movie ‘Avatar’ or Star Trek’s Tricorder, from custom prosthetics to the possibility of printing human organs, 3D printing is on course to transform the healthcare sector presently known to us.

This article delves into the impact of 3D printing on medicine, focusing on two main areas: The use of performing arts to convey practical information involves the rendering of information such as; custom prosthetics and organ transplants. In the next tutorial, we will find out how this technology is implemented in practice, what is the state of the art, and what can be expected in the future.

What is 3D Printing?

Let’s first discuss the topic of 3D printing before going further into its use in medical practices. Indeed, 3D printing also known as additive manufacturing is a technique in which objects are produced in 3D in successive layers with the help of a model in digital format. These layers are then of plastic, metal, or even biological tissues that are derived from animals or plants.

The process begins with a digital plan, which is endured in the 3D printer. On the material platform, the printer puts down layers of material with the final aim of forming the object. This makes it possible for the designer or architect to have a close say on the sizes, form, and construction of the final product.

Custom Prosthetics: A New Era of Personalization

Traditional vs. 3D Printed Prosthetics:

Originally, most prosthetics were costly and it took a relatively long time to come up with them. Sometimes, a fitment and readjustment might have had to be made several times before the correct size was attained. This process could take weeks if not months and in the end, the patience the patients have to have while waiting for the prosthetics they require.

In 3D printing, this process is severely shortened. Prosthetic devices can be developed and produced in a very short time – in hours or days depending on case complexity. Here, the models involved in 3D printing are digital, and as such, one gets a perfect fit based on the patient’s body. This leads to a better and more usable prosthetic for the people who need it.

Benefits of 3D Printed Prosthetics:

  • Cost-Effective:

Fixed prosthetics can range from a few thousand dollars up to the cost of $10,000 while the 3D printed ones will cost a few hundred dollars at most. This makes them easily available together with their services to most of the patients especially those from the low-income bracket.

  • Speed:

The time for producing is considerably cut, so patients cannot wait for their turn for so long.

  • Customization:

This means that each prosthetic that is to be made can be unique to the patient and be more comfortable and functional.

  • Innovation:

New materials and designs like light structures or flexible joints can be created with the help of 3D printing.

Real-World Applications:

Probably one of the most revolutionary methods that use 3D printing is the provision of prosthetic limbs, especially to children. The traditional prosthetics are very costly and that is not for a period of time that the child will grow and, therefore, the child will require a new one to fit him or her. While some experts have discussed the problem of using traditional techniques in regions with a huge population density, 3D printing seems to be more cost-friendly and can be further upgraded or replaced when necessary.

There are also organizations whose main agenda is to distribute 3D-printed prosthetics where such needs are especially felt; such as in the third world. Such attempts have impacted the lives of thousands and given the ability to move around and be independent to those who were unable to do so before.

Organ Transplants: The Future of 3D Bioprinting

The Organ Shortage Crisis:

Transplantation of organs has always presented a lot of difficulties because of the scarcity of the organs. Millions of people are on waiting lists and tens of thousands, if not more, never get the organs they wait for. The shortage of human control tissue has therefore been compensated by the exploration of other methods such as 3D bioprinting.

What is 3D Bioprinting?

3D bioprinting can also be described as a higher life form of the better-known 3D printing technology which incorporates living cells for the bio-inks. These bio-inks are then applied in successive layers to form tissues and, in the process, organs. Although that is still a relatively recent technology, the opportunities are vast.

Current Progress and Challenges:

  • Printing Tissues:

Doctors have already attempted to print mere tissues, for instance, skin and cartilage tissues. These tissues can be employed for experimentation, testing of drugs, or can be applied as grafts in certain operations.

  • Complex Organs:

The last prospect is to print such body organs like hearts, kidneys or livers for instance. But this has its drawbacks – foremost of which is the formation of the hundreds of thousands of micro blood vessels needed to supply these organs.

  • Ethical Considerations:

The issue of producing human organs through printing will create more concern particularly on the life definition and especially on the creation of “order-made” organs. They will have to be resolved as technology advances because the nature of social relations is constantly evolving.

The Road Ahead:

Although we are several years away from having fully formed functional organ tissues the advancement made in this field is encouraging. Scientists are continuing to develop the technology in the hope of eradicating the problem of organ shortage in the future. Picture a world in which every person in need of an organ transplant gets an organ fully compatible with them, as there is little chance the organism will reject it – because it was grown using the patient’s own cells.

Conclusion

3D printing has advanced in the sphere of medicine, especially in the aspect of prosthetics and in the sphere of transplantation and surgery. Its capacity to produce customized and affordable solutions has changes lives and can be expected to do more in the future.

Thus, it is possible to state that the prospects of 3D printing look incredibly promising in medicine. Be it concerned with manufacturing inexpensive prosthetics to supply to needy patients or directed towards making way for pioneering techniques of organ transplant, this technology has the potential to redefine the concept of medicine.
