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.
The process starts with a concept or idea.(Mashable) The first stage of 3D printing is planning out this concept with either computer aided design or animation modeling software. There are tons of programs out there today with these capabilities. Google SketchUp for example is known for being easy to use.(3ders) Using some easy tools that can be learned quickly, edges and faces can come together to make very intricate models. It can even be used with Google Earth. All those models of the world in that software are made in what is basically the same process digitally. Blender is the free 3D creation program that exists for the needs of major operating systems.(3ders) It is a high end software containing features that are much more capable than Google SketchUp. Tinkercad is a newer way of creating designs for 3D printers and works slightly faster than the others.(3ders) Containing only three simple tools, it’s effectiveness for creating models is among the best..
Every single program will be able to create a virtual diagram and outline of the concept being implemented on the printer. Then the program divides the concept into digital ...

The most interesting part of this article for me was learning that researchers and surgeons have already developed so much information on regenerative medicine. I had no idea that simple organs such as bladders and tracheas were already being rebuilt and put into humans. This field is very interesting to me and it seems like difficult work but I think that everything that comes out of it will be helpful to the medical field and human health. The way they are able to take something as small as a cell and turn it into a functioning organ is surprising to me. I knew about the growing list of people who need some type of transplant and the fact that researchers are looking for a way to diminish this list is amazing. It seems to be a growing field of study and I hope that many bright researchers join this study of the human heart and regenerative medicine.
Many ailments can be cured or at least ameliorated by the replacement of an organ and the progression of medical science has increasingly allowed more types of organs to be successfully transplanted. Doctors’ ability to transplant is thwarted, however, by the disproportionate number of patients in need of such life-saving treatment relative to the number of donor organs available. Due to a variety of circumstances there just aren’t enough spare organs to go around. In light of this situation and the ever increasing number of people who die every year while waiting for an organ donor, xenotransplantation has become a very attractive alternative to human transplants, for obvious reasons. While there may be a shortage of human organ donors, we can easily envision animals being bred for their organs and providing an almost unlimited supply.
In the world we’re living in today, many kinds of diseases, infections, and viruses are continuously arising. At the same time, scientists are untiringly researching about how we can prevent or cure them. Unfortunately, millions of people have been affected and sick that some of their organs fail that results to the need of organ replacement. Many people have died because no organs have been available to provide the need of organ replacements. The shortage of organ replacement has been a bioethical issue since then and it seems like no solution has been available. However, due to the studies scientists have been conducting, they found the most possible answer to this issue – Xenotransplantation. It hasn’t become very popular all over the
3D printing has the potential to revolutionize the way we make almost everything. 3D printing was invented in the mid 1980s and was initially known as additive manufacturing. It consists of the fabrication of products through the use of printers which either employ lasers to burn materials (sintering) or place layer upon layer of material (known as stereolithography), eventually resulting in a finished item. Unlike the traditional manufacturing process, which involves milling, drilling, grinding or forging molded items to make the final product, 3D printing “forms” the product layer by layer. There are many different technological variants but almost every existing, 3D printing machine functions in a similar way: a 3D computer-aided engineering (CAD) file is sliced into a series of 2D planar sections and these are deposited by the printer, one above the other, to construct the part.
But at the same time it is not possible to apply this result / estimation to all procedures as the precise risk will vary from one procedure to another, depending on a range of factors which need to be observed over a long term. The US Public Health Service agencies (i.e., FDA, Centers for Disease Control and Prevention, National Institutes of Health, and Healthcare Resource Services Administration) and the Office of the Associate Secretary for Planning and Evaluation of the Department of Health and Human Services are collaborating to develop an integrated approach to be applied at societal, institutional, and individual (patient-physician) levels to address infectious disease issues in Xenotransplantation.

The Benefits of Xenotransplantation New technology has opened many doors of opportunity for advancements in medical science. Not even in our wildest dreams would we have imagined a world where animal organs could be safely transplanted into humans. A few years ago, this process, called xenotransplantation, was completed for the very first time. The only dilemma critics had with the process involved the chances of infection and organ rejection from the patient. Through experimentation and advances made in the process, these problems have been greatly reduced.
People nowadays might get the impression that the 3D printing technology is a relatively new concept in our daily life. However, 3D printing technology is invented and utilized in many fields such as creating human organs in healthcare, building architectural models in engineering, even forming components that can be used in aeronautic fields long ago. Since Charles W. Hull has invented the 3D printing technology in the 1980s, scientists, engineers, and even normal people were and still are trying to discover more possibility of the usages and changes on this technology. Same as every invention of the new technology, with its undeniable beneficial effects, 3D printing also faces lots of limitations
No medical procedure is perfect, and when it comes to organ transplants, perfection is still far on the horizon. Our bodies are designed to be efficient and productive, yet consistently challenged and changing. In the case of organ transplants from donor to recipient, problems are almost always sure to arise. Hyperacute, acute, and chronic graft rejections are defined as the three possible negative outcomes of the transplant of a human organ. A disease defined as graft-versus-host-disease characterizes other problematic situations arising from human transplantation. Human transplantation is far from perfect, and the ever-increasing research behind xenotransplantation is starting to give hope to a more efficient and readily available option.
CAD-Computer Aided Design Computer Aided Design systems make it easy to create a picture of a new design, then you are able to change the picture on the computer. This saves time because you don’t have to re draw everything from the way it was originally started of with. It is also quicker to evaluate. There are many different types of CAD programs available to the industries and designers.
Printmaking is an art or medium that has grown popularity within the last century. It has many forms with different complexities but all forms are based on the same principle, which is to transfer an image from a matrix to a transferring base.
It is normally done in three steps as Designing, Printing, and Finishing. The designing part is done by using Computer aided design (CAD). Then Virtual Reality Modelling Language (VRML) files are sent for the input of 3D Printers.
Xenotransplantation is the science of the future. By taking animal organs and putting them into humans, we eliminate the loss of life due to scarcity of human organ donations. No longer should the sick have to wait for their new organ because of the scarcity of human organs available to be transplanted.
