The, Three Dimensional Printing Of Tissues

Organ donation provided a new therapeutic path when new drugs and devices failed to reduce the mortality and morbidity rate of patients with such illnesses as cardiovascular diseases. By replacing damaged organs or tissue with a functioning substitute, organ transplantation offers an immediate cure. Unfortunately, this “cure” is never guaranteed because of the high risk of graft rejection and that’s if a suitable donor can be found. Thus, tissue engineering has been the projected new treatment for these problems. Tissue engineering replaces the diseased or damaged tissue or organs with biofabricated counterparts made using the specifications dictated by the features of the specific tissue or organ.

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.

In a study conducted through the U.S. Department of Health and Human Services on “average 79 people will receive an organ each day; however, an average of 22 people die each day” waiting for transplants that cannot take place because of the shortage of donated organs (U.S. D.H.H.S). The average amount of patients waiting for an organ can reduce to zero with the continued development of 3-D printers. 3-D printing is a process of making three dimensional solid objects from a digital file. The digital file is uploaded onto a computer software, and then the 3-D printer prints the digital file out onto different materials. The materials include plastic, resin, nylon, sandstone. The finish products become replicas of the digital file, and what was an idea is now a reality. Therefore, 3-D printers will one day be the future of organ transplants because over the past twenty years the technology industry has rapidly grown into the focal point in society. From advancement in communication, to the medical field, science and technology has shaped this world today. Thus, the American Government should invest more money into the medical field budget because the research conducted on new technology (3-D Printers) leads to more lives saved, and expands the opportunity of future medical breakthroughs.

Secondly, advanced 3D printing applied to the medical field can be utilized in an Engels non capitalist technology drive society to impact the area of safety. In this utopian society, advanced 3D printing will have the capabilities to print synthetic tissue and organic tissue that can bond to the patient’s cells. In effect, this helps the patient’s wound heal faster. This type of advanced 3D bio printing can save many lives

Doctors and engineers have been working on another way to get organs a faster and more efficient way. Using 3D printers can help with their problem. They have worked on using a 3D printer to make organs that are a perfect match for patients. This can be very useful it can get an organ ready in a short amount of time helping the patient recovery faster as well. Organ transplants are hard to come by. One you have to be put in a waiting list, and people are usually on that list for a long while, just waiting for a perfect match to come. But sometimes it takes to long and some people die while still on the waiting list. But when an organ finally does come they feel bad because someone had to die in order for them to use it. So Dr Ali Khademhosseini is trying to use 3D printing to help solve this problem. His theory is he can make organs from a 3D printer, which can make the waiting list decrease faster and have people not have to die in order for a perfect match. 3D printers have been used to make Human cells, tissue, and blood vessels. But making something like a heart is much more difficult. Because you have to make the beating and pumps. (Mesley). There have been problems in the past that have just know started to show in some people. "Viruses aren't the only worry, and here too the past may serve as a guide. In 1956 injections of human growth hormone became a standard therapy for children failing to develop properly. The hormone was extracted from

The purpose of this experiment is to test how scientists can most efficiently complete organ printing. In this lab, the cells will be suspended in a substrate called sodium alginate-collagen, hydrogel, and other reactants. These materials will react to then embed the cells to their goal location. Then, the cells will be able to be fixated into layers. These layers will then come together and form tissues, which according to biological organization will form organs. The inkjet bioprinter allows for this to occur. Tiny ink droplets form a digital design for the organ printing, and in horizontal sheets, the organ is created tissue by tissue. This lab will test to see which percent concentration of the sodium alginate-collagen composite will prove to be most effective when organ printing. The dependent factor that will determine the conclusion will be the percent of efficiency of cell survival rate. Four trials will be completed in which the same organ is printed and all factors are kept constant, except for the percent concentration of the substrate.

Kaiba Gionfriddo was born prematurely in 2011. After 8 months, his lung development caused concerns, although he was sent home with his parents as his breathing was normal. Six weeks later, Kaiba stopped breathing and turned blue. He was diagnosed with tracheobronchomalacia, a long Latin word that means his that windpipe was so weak that it collapsed. He had a tracheostomy and was put on a ventilator – the conventional treatment. Still, Kaiba would stop breathing almost daily. His heart would stop, too. Then, his caregivers 3D printed a bioresorbable device that instantly helped Kaiba breathe. This case is considered a prime example of how customized 3D printing is transforming healthcare as

Thump, thump… thump, thump… thump, thump. That is the sound of Nature’s most perfect machine, the human heart. It epitomizes the idea of natural engineering through its complexity and contribution to the vessel that holds it. But, can it be synthesized by the species that possesses and depends upon it? With the emerging 3D printing technology in the field of regenerative medicine, the answer may very well be yes. However, a question to consider before humanity embarks on this endeavour: do the life-saving advantages outweigh the various disadvantages?

3D printing is definitely a huge advancement in Technology! However, very controversial. Although, it has multiple benefits in our society in Medical health practices & Engineering speed, it can also be used for illegal purposes. Now, does the bad outweigh the good? That is the question debated today. I see the whole concept in only 2 large points. It will greatly help people who are desperately in need for transplant organs. It will drastically reduce the organ waiting list and once perfected, our life span should be bumped up a decade or so. On the other hand, what if someone down the road you'll be able to completely recreate a human being in it's entirety? Would we harvest them for their organs? Would it be fair? What if it falls in the

In the future, the technology will be widely accepted since it can be used to create complete organ, to test newly developed drugs on manufactured cells instead of animals and human cell, to imprint cells directly onto a human body, thus reducing the wait time for organ transplantation, and save time and cost associated with drug research. An absolutely favorable position of customized organs is designing organs utilizing a patient 's own particular cells. With this methodology, there would be no issues with dismissal, and patients wouldn 't need to take the powerful anti-rejection medications that are presently required (Cooper-White, 2015). According to the Organovo company, the formation of a suitable liver is a crunch second for the bio-printing and drug industry since it demonstrates 3D printed tissue can be preserved successfully for a sufficient time to test the impacts of medications on it or insert it in a human body where it can further mature (Mearian,2013).

The goal of the pigoon project was to grow an assortment of foolproof human-tissue organs

Bioprinting is very advanced and hard to do correctly. Bioprinters are open to the public, meaning that anyone could obtain one. If anyone can obtain the power to use a bioprinter because there are no requirements it means that someone could wrongly create a prosthetic limb or other major parts. If they are wrongly created and given away then, someone can be severely harmed. “3-D printing using computer-created digital models to create real-world objects, has produced everything from toys to jewelry to food” (Griggs). This means that people use computer based programs to create their projects. After they create their project it gets sent to the bioprinter and then it uses to online program to print the project. Also, “Eyeballs, skin, ear replacements, and organs such as livers are in the works in a new field called bioprinting” (3D Printing: The Future is Here!). This shows that people have begun to do more advanced things with bioprinter and anyone is allowed to use a bioprinter. People without proper education or knowledge trying to successfully do this will ruin the whole project. Using bioprinters correctly is hard and there is a certain amount of thought that needs to be put into to it. As of right now there are no laws or regulations limiting the people who can and cannot use the printers meaning if someone does not know what they are doing they can still try and do it incorrectly without

The kidney printed for the transplant was not able to be used as it was not a live organ and it couldn 't function as a human kidney would. Researchers by their nature are eager to embrace new technology the medical 3D printing industry has evolved in the past years. Today the researchers are trying to 3D print bones that can be transplanted in replacement of an injured bone.”As of now, the only patient to benefit from the new printer is a rat”(Abram). The 3D printed bones have not experimented on humans yet. So far the 3D printer has been used to print bones that can be implanted into rats. The material used to print this bone was the rat bone itself. The 3D printing technology has advanced in the field of medical science by improving health care.

With the very limited supply of organs, 3D printing creates functioning organs without a donation from a living organism. The definition of 3D printing from Charles W. Hull, the inventor of 3D systems, states that “...thin layers of a material that can be cured with ultraviolet light were sequentially printed in layers to form a solid 3D structure” (Murphy & Atala 773). The sheer narrow sheets play a vital role in bioprinting. They allow the printers to develop functional, layering individual cells, proteins, and an extracellular matrix. The three basic types of 3D printing include biomimicry, independent self- assembly, and miniature tissue blocks. The creation of the 3D structure creates all the difference between these types of printing. Three dimensional structure approaches include, creating exact duplicates of the cells and tissues with extensive knowledge, using a developing embryo as a template or using microscopic tissues to assemble into a larger developed tissue (Kalaskar). In other words, all these paths to bioprinting end up with a 3D structure but require different knowledge and materials. They all contain their own sets of challenges.

First you start with a blueprint outlining the desired structure of the organ(22). Then you move onto the 3d printing machine, such as a Regonovo capable of running the inkjet sub-method of 3d printing(15). This type of 3d printing is designed to build the desired object, or in this case organ, by laying down the material layer by layer and allowing it to fuse together along the way, allowing it to maintain structural integrity. Within a bioprinter there is bioink, which is a cell filled
