Recommended: Printing organs for the human body
Eighteen people die everyday on average due to the fact that they cannot get the necessary organs they need to save their lives. Due to the lack of organ donors and the lengthy process it takes to receive an organ, Despite printing 3D organs to help save lives and create a better life how do we know that this technology will uphold its task? This technology is capable of producing complex organs however, the printed organs to function inside the human body can be a complete utter myth. Despite the fear of overpriced printed organs not functioning correctly in the body, what is the harm if the success rates are more than failures. Organ printing or use of fast prototyping, additionally characterized as added substance layer-by-layer bio-manufacturing, is a rising changing innovation that has potential for surpassing conventional printers for strong framework based tissue designing (Pace). Organ printing has certain focal points: it is a computerized approach that offers many different pathways for adaptable reproducible large scale manufacturing of tissue designed items; it produces concurrent 3D situating …show more content…

Personal Credibility: I have always held a curiosity about the anatomy and physiology of the body and all the parts that work together to keep us alive. Equally, it is extraordinary that medical advances have made it possible to undergo surgery to replace a failing organ with a thriving new organ, further saving a life. According to the United Network for Organ Sharing statistics: Every 10 minutes another name is added to the national organ transplant waiting list. At one point in your life, you will know someone who needs a transplant.
One of the most exciting new technologies being developed today is the manufacture of replacement body parts to be used to treat illnesses in humans. Today, this is accomplished in part through the use of bio-printing to 3-D print living cells into more complex structures. In the movie, The Fifth Element, there is a scene that takes this technology to the extreme and manufactures an entirely new human. The process used in the movie starts from a sample of one cell, preserved inside of a metal gauntlet, and then proceeds to recreate the person whose cell that used to be. The print in the movie is physically done by creating one part of the body, such as the skeleton, at a time. The entire print in the movie only takes around two minutes.
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...
Human organ transplantation is known as the removal of a living tissue or organ from one individual by surgical operation, and it is placed into another individual, with the aim of improving the health of the recipient. It was started in the 1930s. In 1933, human renal graft was tried out by Voronoy, a Russian scientist, and it has vastly advanced since then. Human organ transplant is now viewed as treatment rather than experiments as they can now be performed more safely. This has been seen by the remarkable improvement on the medical care of patients with organ failures i.e heart disease, cirrhosis and renal failure.
Solid Freeform Fabrication(SFF) has been possibly the most large scale fabrication technique among the different types of design and fabrication methods (Bose, et al., 2012). The main feature of SFF has three dimensional parts which are printed layer-by-layer depending on computer aided design (ask plagiarism). The fabrication of SFF on polymer, ceramic, metal and composite scaffolds has been widely accepted in bone tissue engineering applications (Bose, et al.,
The possibilities 3D printing can achieve are countless. This might be the most controversial and impactful technology of the future, as Hod Lipson quotes again, “When it costs you the same amount of manufacturing effort to make advanced robotic parts as it does to manufacture a paperweight, that really changes things in a profound way”
This will even be further refined and we will simply print out replacement parts as needed using a modified 3-d printer similar to what we have today. Whether printed or grown this advancement will have the potential to extended human life well beyond what we currently think the limits are. The pros for this advancement would be simply that what we consider life altering diseases or accidents would simply be a temporary condition until replacement parts are either printed or grown and then used to replace the defective areas. This has a clear potential to end several common modern conditions and allow people a normal life beyond what we can manage today. Cons to this advancement are numerous but the most apparent is when we combine genetic manipulation and this technology we can produce genetically superior body parts. Thus, the human condition we have at birth will be thrown out and replaced with something beyond our imagination. This also has a con in that as with genetic manipulation towards a superior human if someone had an ulterior motive they could in fact insert a type of gene marker that if activated could potentially kill the recipient or be used to control a person through either overt blackmail or covert control. AS is the case with all advancements we have looked at thus far we would need to manage this one and ensure the safety of anything being used to replace a body part is not modified to the detriment of the person receiving the replacement
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 greatest problems in medicine today is that many people need organs for various reasons, which are not available, and lead to a lot of unnecessary deaths. There are not enough organs to supply the need in demand. In 1997 "2,300 of 40,000 Americans" that needed a heart transplant got one; that means that nearly 94% did not receive one (Fox). I know from having heart problems myself, that if I would need to have a heart transplant sometime in the near future to stay alive that I would definitely want a cloned heart if nothing else was possible and I was able to receive one. Why, you might ask? Because I have not had a chance to live my life, and there are many other things I would like to experience, such as celebrating my twenty-first birthday, getting married, and having a family. But if we cloned human organs we would eliminate a major killer to the human race, and provide patients worldwide with a healthy cloned organ.
In order to analyze its pros and cons, we need to know the technology first. As one of the advertisements states, “3D Printing: Make anything you want”. Of course, with the current maturity of this technology, this line exaggerates its effects, yet it certainly has a point. 3D printing is “a mechanical process whereby solid objects are created by ‘printing’ successive layers of material to replicate a shape modeled on a computer.
Selling organs will saves lives in many different ways also. People are dying because they are illegally selling their organs in the black market or even selling there organs in insane prices to other people. As in Germany, it will coast around $3500 to donate a liver. But in other i...
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.
Biomechanical engineering is driven by needs similar to those of biomedical engineering. There is always a constant need to improve medical equipment while keeping it cost efficient. These are the two main needs for all biomedical engineers. Biomechanical engineering is specifically dedicated to applying the scientific of knowledge mechanical systems and engineering to biology and the human body. One of the many needs that drives this biomedical subfield is society’s need for more advanced equipment and machinery. Some recent advances show this need. In the last decade, biomechanical engineers have invented and innovated new robots and machines that can assist a surgeon in surgery or serve as an artificial liver. These machines satisfy the need to improve and innovate new equipment that can save lives and improve how people in the medical field perform their
The idea was to improve 3d printer with special technology, a single printer, with multi material features, can transform from any 1D strand into 3d shape, 2d surface into 3d shape or morph from one 3d shape into another. The shape of 3d technology is basic mode for 4d. Objet Connex multi-material technology is an 3D printing important part of his work – and is being used extensively in this new process. The Connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the materials to active the self-assembly process. With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non-electronic based materials.
Consider the impact of the new technology on both computer professionals and computer users, including relevant ethical, legal or social issues.
