AS well as sustaining the ability to produce prosthetic limbs, 3d printing is also extremely useful for creating artificial organs for needy patients in hospitals. But not only organs, but skin, bone, cartilage, blood vessels, surgical tools as well as even hearts and stem cells can just as well be made by these magnificent machines.
Tissue engineering is an emerging interdisciplinary field that uses principles from engineering, biology and chemistry in an effort towards tissue regeneration. The main draw of tissue engineering is the regeneration of a patient’s own tissues and organs free from low biofunctionality and poor biocompatibility and serious immune rejection. As medical care continues to improve and life expectancy continues to grow, organ shortages become more problematic.(Manufacturing living things) According to organdonor.gov, a patient is added to the waiting list every 10 minutes and an average of 18 people die everyday waiting for an organ donation. The “nirvana” of tissue engineering is to replace the need for organ donation altogether. This could be achieved using scaffolding from
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.
SINcE I hAVE ALwAYS BEEN INTErESTEd in science and technology, I subscribed to many research magazines, including Popular Science and Scientific American. However, until 10th grade, I never had the opportunity to contribute to medical research—something that I had always wanted to do. Then, one day I read an article titled “Print Me a Pancreas, Please” in Popular Science, which described novel tissue engineering research involving modification of off-the-shelf inkjet printers to print out living cells in a “bioink” solution. Having read much about tissue engineering, I realized this “organ printing” approach could potentially address problems of traditional tissue engineering methods, such as the need to precisely place specific cell types in 3D scaffolds. I was so excited that I came up with a few ideas of my own about advancing the
Preliminary Data 3: Tissue engineering scaffolds comprised of decellularized myocardial extracellular matrix effectively emulate the natural cardiac environment. In order to best reconstruct the damaged tissue of a heart following myocardial infarction, the chemical and biological cues that dictate cell recruitment and differentiation in the native tissues are required. Each human tissue contains its own specific combination of proteins and proteoglycans within the ECM to facilitate this process, so it serves that scaffold material obtained from the heart would best serve to reconstruct cardiac tissue (Singelyn et al. 2009). Modifying the scaffold into an injectable form would allow for the noninvasive delivery of the therapy directly to the affected site. Previous studies on the gelation of a decellularized porcine myocardium ECM scaffold have found it satisfactory in mimicking the natural environment of the heart (Singelyn
Traumatic acute events leading to tendon losses as well as ruptures related to degenerative tendinopathy require a replacement of the damaged tissue. Yet in these cases, the healing process does not efficiently restore the native tendon structure and function, despite the surgical intervention with a high rate of re-tear (Sharma and Maffulli, 2006; Andarawis-Puri et al. 2015). Nowadays, tendon autografts are the common choice to reconstruct the tendon integrity, despite their limited supply, high donor-site morbidity, and poor functional outcomes ( Gazdag et al., 1995; Lovati et al., 2016). To overcome these limitations, tissue engineering widely investigated the generation of cell seeded scaffolds to promote regeneration and implant-tissue
On Wednesday April 13th, 2016 Madonna University held a convention that included the topic of 3D prosthetic printing. This convention helped bring awareness and information of how 3D prosthetic printing works. The whole experience was an opportunity to better understand the world around us. People are living with hand disabilities all around the world and feel as if they don’t have the same opportunities as people who don’t have a hand disability. This experience was excellent because I met people who had the same interests as I did, which is helping others. I got into a group with 2 other students from Dr. Olla’s class as well as a group of women. We taught these group of women how to put together a 3D prosthetic hand. The women seemed to
The process of bioprinting is a method in which using three-dimensional (3D) technologies to produce cell-encapsulated hydrogel. An advantage of this process compare to the other conventional fabrication technologies is that the cell distribution inside the scaffold can be controllable. Alginate, as natural polysaccharide was called,

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.
Tissue engineering has been an opportunity to restore the human condition from wounded to whole through the combination of biological, biochemical, and biomechanical concepts. Unlike traditional transplantation, tissue engineering and regenerative medicine uses a patient’s own cells to fabricate new tissues which are then grafted back into his or her body. Of course, the goal is to apply the practices in the lab to the general public and to develop a new and more effective means to treat patients with severe tissue loss and/or organ failure.
One of the most complex processes that is being investigated in 3D printing is the printing of tissues themselves. It is the same process as printing all other objects, with the only difference being in the extremely complex materials and structures that need to be printed. The only tissue that can currently be printed is cartilage, being of the “simplicity” of the tissue; it is only a single stratified cell that is easily adapted and not nearly as complex as printing organs. The dumbed down version of how the tissue is printed is by creating a type of frame of biocompatible materials such as gelatin and thermoplastics, and adding a bio ink made of cartilage cells to the frame, which theoretically creates a cartilage that’s both strong and soft to most resemble real cartilage. The initial problem of creating an ink that is liquid at room temperature (to print) and solid while at body temperature was solved by a few groups of scientists. The perfect combination was a mixture of N-isopropyl acrylamide and hyaluron which is liquid at room temperature and solidifies when printed onto a surface heated to body temperature. (New Material Mixture for Bio printing Cartilage). The future of medicine lies in 3D printing, and it is knocking on the doors at this very moment.
All over the world, there are children from all ages and adults that are in need for organ donation. Unfortunately, not all the patients in need of an organ transplant will receive one on time. This can occur because their name wasn’t on top of the list to receive a transplant. Thus, they remain in treatment to avoid full organ failure, which only helps for a certain amount of time. In contrary, the patient that receives the transplant can have another chance of life. Although there is also a probability of rejection. Then the process repeats itself again. Another possibility for this cycle to end is 3D printing. Through the advancement of this research and technology, there is a possibility of that a 3D
3D printing is a recent technology that is springing up all over the world, and is being used to create innovative and exciting things. A 3D printer works by first using a “blueprint” created by a user on a computer in certain programs. This object can be almost any geometric shape possible. The printer will then take the blueprint and synthesize the object slowly over time. These objects are created by the printer placing each layer over layer of the object on a 3-dimensional grid until it is fully replicated. Shown right is a 3D printer purchasable for $2500, a high end consumer-level printer. This printer is only capable of producing static, but complex objects designed by the user. The materials that the 3D printers utilize depends on the type of the printer. There are certain printers that are consumer grade, similar to above, and can only print small, “knick-knack” like objects. These printers print with different types of plastics. Industrial grade printers also exist, which can utilize anything from plastic, polymers, and even metal alloys. In the medical field, however, living cells can be used as a building material in specialized printers. Scientists from the University of Edinburgh have developed a cell-printer that can print using living embryonic stem cells. This technology is one of the first stepping stones that can be used for testing new drugs, growing organs, and printing cells directly inside the body (LiveScience). These embryonic stem cells are obtained
We live in a time where technology is improved and advanced every single day. The health care environment is no exception. The technology used for health care is constantly being refined and advanced in hopes to allow even better and more efficient care. One of these technological advancements that could revolutionize health care is 3D printing. Benefits 3D printing could provide include construction of prosthetic limbs as well as anatomical models aimed at determining patients’ needs and many more (Ventola, 2014). However, there are also disadvantages of this technology and one of the main disadvantages is the security issues it presents. There are both advantages and disadvantages of 3D printing but there is no denying the promise of this technology and the potential impact it could have.
