In 1983, the first 3D printers were created, and began a revolution in the technology world. These printers are just starting to reach their potential, and can be used in almost every field of work that exists. Just recently 3D printing has started to affect the medical industry and they can be used in many ways. One of these ways is by 3D printing organs made from your own cells. Many people believe that this is just science fiction, but recent developments show that 3D organ printing is not too far away. Right now in the US and countries all around the world there is an enormous shortage of organs and 3D printing could help to solve this crisis.
The history of organ transplants includes many different efforts, which none have been too successful. The main problem is that there are not as many donors and patients. Waiting lists have up to 95,000 people on them and less than 1/3 receive adequate organs. Many patients on the wait list end up dying, and this is becoming a problem of huge importance. Other efforts to stop the crisis have been rewarding the families of donors and educating the public about the benefits of donating organs. Neither of these has generated enough donors to stop the problem. 3D printing would be the quickest way to save these people’s lives. The 3D printers use layers of materials to construct objects. This process is called additive manufacturing. When they print layers of biomaterial to form cells and tissues it is called bioprinting. Bioprinting is what will be used to construct the 3D organs. Previously scientists have printed structures that only have one type of cell. That is because they are easier to print and are very simple structures. That includes skin for burn victims. Also tubular structures...

...anies with more accurate data. Many bioprinters are also now being sold. The Bioplotter is a printer capable of printing human tissues. It sells for around $188,000 for each one. Organovo has sold bioprinters to other companies. The industry of bioprinting is quickly becoming one of the fastest growing around the world.
3D organ printing has advanced a long way from 1983 when 3D printers were first created. They have the potential to save thousands of lives and solve the lack of organ donors crisis. They are also making the bioprinting industry much larger with a lot more attraction. It is currently small, but is on the rise. 3D printed organs will be very expensive though and there is a lack of funding. Also researchers are not sure that 3D printed organs will be able to survive for long periods of time. If they do, 3D organ printing will change the medical world.
Brendan Maher, in his article “How to Build a Heart” discusses doctor’s and engineer’s research and experimentation into the field of regenerative medicine. Maher talks about several different researchers in this fields. One is Doris Taylor, the director of regenerative medicine at the Texas Heart Institute in Houston. Her job includes harvesting organs such as hearts and lungs and re-engineering them starting with the cells. She attempts to bring the back to life in order to be used for people who are on transplant waiting lists. She hopes to be able to make the number of people waiting for transplants diminish with her research but it is a very difficult process. Maher says that researchers have had some successes when it comes to rebuilding organs but only with simples ones such as a bladder. A heart is much more complicated and requires many more cells to do all the functions it needs to. New organs have to be able to do several things in order for them to be used in humans that are still alive. They need to be sterile, able to grow, able to repair themselves, and work. Taylor has led some of the first successful experiments to build rat hearts and is hopeful of a good outcome with tissue rebuilding and engineering. Scientists have been able to make beating heart cells in a petri dish but the main issue now is developing a scaffold for these cells so that they can form in three dimension. Harold Ott, a surgeon from Massachusetts General Hospital and studied under Taylor, has a method that he developed while training. Detergent is pumped into a glass chamber where a heart is suspended and this detergent strips away everything except a layer of collagen, laminins, and other proteins. The hard part according to Ott is making s...
In 1954, the first organ transplant was conducted successfully in the United States. (Clemmons, 2009) Nowadays, the technology of organ transplant has greatly advanced and operations are carried out every day around the world. According to current system, organ sales are strictly prohibited in the United States. (Clemmons, 2009) However, the donor waiting list in the United States has doubled in the last decade and the average waiting time for a kidney is also increasing. (Clemmons, 2009) In the year 2007, over 70,000 patients were on the waiting list for a kidney and nearly 4500 of them died during the waiting period. In contrast to the increasing demand for kidney, organ donation has been in a decrease. (Wolfe, Merion, Roys, & Port, 2009) Even the government puts in great effot to increase donation incentives, the gap between supply and demand of organs still widens. In addition, the technology of therapeutic cloning is still not mature and many obstacles are met by scientists. (Clemmons, 2009) Hence, it is clear that a government regulated kidney market with clear legislation and quality control is the best solution to solve the kidney shortage problem since it improves the lives of both vendors and patients.
Currently more than 118,617 men, women, and children are waiting for a transplant. With this high demand of organ transplants there is a need of supply. According to the OPTN Annual report of 2008, the median national waiting time for a heart transplant is 113 days, 141 days for lungs, 361 days for livers, 1219 days for kidneys, 260 days for pancreas, 159 days for any part of the intestine. With this world of diseases and conditions, we are in desperate desideratum of organs. Organ transplants followed by blood into a donating organ transfusions, are ways medical procedures are helping better the lives of the patients.
Currently 70,000 Americans are on the organ waiting list and fewer than 20,000 of these people can hope to have their lives saved by human organ transplantation.1 As a result of this shortage, there has been a tremendous demand for research in alternative methods of organ transplantation. Private companies are racing to develop these technologies with an estimated market of six billion dollars.2 Xenotransplantation, or cross-species organ transplantation, appears to be the most likely solution in the near future, and cloned pigs are the main candidates. Pigs and humans have remarkable similarities in physiology, which along with cloning makes pigs strong possibilities for organ donors. A controversial alternative method involves the use of genetically altered headless human beings as organ donors. Although this method may not be developed for some years, scientists are already discussing the necessary technologies. Whether the solution is the cloning of a pig or a human, organ farms may provide us with a solution to our ever-increasing need for donors.
Obstacles and concerns that come along with the ability of 3-D organ printing are the cost, effectiveness, and safety. Not only do the machines themselves cost up to millions of dollars, but think about the cost the patient is going to be responsible for. What happens if your not able to afford the cost of a 3-D printed organ? Does that mean only the wealthy will benefit from this advancement? In one of my articles I read about 3-D printing was; in 2001 there was a 3-D printer called the BioAssembly Tool, or BAT, that was build for about $400,000. And in the past 6 months it was estimated to cost about $100,000 for the total bioficial heart, not including surgery or hospital costs. You also have to think about the amount of electricity it takes for the machine to operate. Since 3-D printing uses the patients cells and builds tissues to fit the patient perfectly, the typical fear of the body rejecting the organ compared to the human organ no longer exists. The safety of 3-D is some what unknown as of now because this is such a new idea and more research needs to be done before it is perfected. You
If relevant technologies continue to develop at their current pace then I expect replacement bones and simple organs to be available within my lifetime, and I don't think we will be able to print an entire human for a long time after that, if ever. One major problem with printing an entire human I see is printing the brain. Not only is the structure of the brain complex, we currently do not know enough about how it works to be able to reproduce
Each of the children did very well with identifying concepts of a book the first child that we will look at is 6 years old. She goes to kindergarten all day and has grown up with many books around. She was able to hold the book right side up for me, show me the front cover, and show me the back cover. She was also able to show me the title page of the book. Lastly she was able to show me the first page of the text. Although she did do a good job of pointing out some main parts of the book she did struggle with a couple others. She wasn’t able to turn some of the pages of the books she would skip three or four at a time. She also had a hard time pointing to the title of the book if it was not in the top of the cover. Lastly the child could not tell me what an author and illustrator did. The next section was conventions of print the child was able to do everything on this list with excellence. She was able to show me where the text was, show me where we start to read at, read left to right, top to bottom and knew that when you reached the end of a line you would have to go to the left...
Dialysis cost more than transplantation, and transplantation would keep more people alive, and would help the economy. People who are not as wealthy would receive compensation for selling their organs. This would help decrease the amount of poverty in certain areas, as well as the financial stability of many. (Should the Selling of Organs be Legal?, n.d.). Another pro would be that people would have to deal with lesser pain, because they would receive the organ faster.
Would restricting healthy persons from acquiring biofabricated products be seen as deprivation of individual rights? Or how sick would a person have to be to be allowed to have his organ replaced? How many replacements of organs of tissues would be possible? As in the case of sports, where performance enhanced methods are used, this problem could also be present in bioprinting, which could advance human capabilities also beyond what is natural. Furthermore, persons could use bioprinted products to exchange their natural, less aesthetic body parts, taking plastic surgery to a completely brand new
3D printing is an incredible new technology that is changing the face of modern medicine. The main goal of 3D printing with biology is in tissue engineering. The article by Jacqueline Jaeger Houtman looks at this “researchers are adapting this exciting technology with the aim of replacing human tissues and organs that have been damaged by trauma or disease” (Houtman). The goal of this technology is to be able to reproduce organs. Currently the only way to get an organ is if someone dies and donates it or if someone living willingly donates. Both require a heavy sacrifice making waiting times for organs very long, many die waiting for an organ. If we can make organs artificially it would drastically shorten wait times. Another benefit is on
There are developments in artificial organs. These organs are getting more accepted and used in the medical field. An article in the BBC news tells of a man whose life was saved by an artificial heart. The man was in desperate need of a heart transplant and people can be on a heart transplant list for even a year. He had an artificial heart implanted in his chest and his original heart removed while he awaited a new healthy heart to become available.
PRINTING PRESS AND STANDARDISATION In 1476, William Caxton introduced England to the printing press. This significant introduction to one of the world’s greatest technological innovations, at the time, helped to increase the spread of literacy and knowledge amongst the British people as the mass production of books became cheaper and more commonly available. According to Mastin (2011), the first book ever printed, although Caxton’s own interpretation was ‘The Recuyell of the Historyes of Troye’ in 1473. Furthermore, Mastin (2011) states that in the following 150 years after the introduction of printing, up to 20000 books were printed.
The field of bioprinting, using 3D printing technology for producing live cells with extreme accuracy, could be the answer to many of the problems we as humans face in the medical field. It could be the end to organ waiting lists and an alternative for organ transplants. In 3D printing technology lies the potential to replace the testing of new drugs on animals. However, the idea of applying 3 dimensional printing to the health industry is still quite new and yet to have a major impact. Manufacturing working 3D organs remains an enormous challenge, but in theory could solve major issues present today.
One of the most beneficial aspects to cloning is the ability to duplicate organs. Many patients in hospitals are waiting for transplants and many of them are dying because they are not receiving a needed organ. To solve this problem, scientists have been using embryonic stem cells to produce organs or tissues to repair or replace damaged ones (Human Cloning). Skin for burn victims, brain cells for the brain damaged, hearts, lungs, livers, and kidneys can all be produced. By combining the technology of stem cell research and human cloning, it will be possible to produce the needed tissues and organs for patients in desperate need for a transplant (Human Cloning). The waiting list for transplants will become a lot shorter and a lot less people will have to suff...
It is revolutionary and life-saving but, has numerous limitations. Let me name three: number one - low donor population (Who is willing to donate anyway? barely anyone). Number two: post transplant infection (Even if there is a donor, what are the chances that the body will accept the transplanted organ? What are the chances of proper function? let me answer those two questions- very low chances) and number three: there is no assurance of survival, which in my opinion, is the worst part of all this.
