The world is always coming up with new inventions that revolutionize the way that humans go about their daily life. Recently it has been computers and the internet. The next big thing will probably be 3d printing although nobody can say for sure. With a 3d printer there are many things that can be done, although for to print some things you need a certain type of printer. Regular 3d printers use ABS or PLS that is heated to create wonderful creations. With a 3d printer it can allow rapid prototyping for companies. It is much quicker than to have a company do it which can span a couple of days instead of a couple of hours.
There are 3d printers in development that allow doctors to create a heart, lung, or other organs created from a persons genetic tissue. At Cornell University researchers were able to create an ear. In San Diego there is a form that has shown the work they've done at printing human livers. Scientists in Scotland are attempting to print blobs of human embryonic stem cells which would be useful for further research on things like cancer testing drugs. Researchers are attempting to create a working heart using 3D printers. A women had a condition where her skull was becoming too think instead of the normal 1.5 cm her skull was around 5 cm. This was causing a loss of motor skills among other things for the woman. She was also having memory problems as well. Doctors had printed out a skull, this allowed the woman to return to life as normal. Since the cells used would be from the person in need of a transplant there is little to no chance of rejection from the body.

...vailable things that can be done with a 3d printer. Many see a 3D printer being common in every home one day. They are objects of the future. The ways they can be used is almost infinite. Hopefully one day they can be used to give better lives to those who wouldn't live well otherwise, if someone had a faulty heart they can get a new one printed with little or no chance of rejection, or if someone who wouldn't be able to get nutritious food now will be able to have food cartridges that can help them eat so they don't become malnourished, or if there is just a student who wants to learn about engineering and circuitry can build one then use it for educational purposes as well as recreational purposes. There are many different types of 3D printers, each with a different function of what they can do. One day they'll greatly improve the 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 “Death’s Waiting List”, Sally Satel presents a strong and compelling argument for the implementation of changes to the organ donation system. The author addresses a shortage of organ donations due to the current donation system in the United States, which puts stipulations on the conditions surrounding the donation. She provides ideas to positively affect the system and increase organ donations.
First, a demonstration of the kind of technology available today would lend to a better understanding of some of the biological possibilities. Already we can clone and manipulate individual genes. We can replicate DNA patterns and build proteins. Information is available at the touch of a button on the newest technology, so that it can be ingested by the younger generations just by browsing the Net. Also, the beginnings of nanotechnology, manipulating individual atoms to create new structures, is beginning to develop. James Graves wrote in a paper focused on the technological advances in our time, that nanotechnology, not too unlike the theories behind Vergil's experiments in Blood Music, would allow us to create tiny "organisms" that could show us more about ourselves, r...

It is clear that a large demand for organs exists. People in need of organ donations are transferred to an orderly list. Ordinarily, U.S. institutions have an unprofitable system which provides organs through a list of individuals with the highest needs; however, these organs may never come. A list is
In order to analyze its pros and cons, we need to know the technology first. As one of the advertisement 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 in a computer. ” To put it more vividly, the printing process of a 3D printer is like to make a melaleuca cake with various materials. And “the materials”, as the inventor of this technology Charles W. Hull once wrote, “include polymers, metals, ceramics, composites, food, probably other things, too” . So, imagine these materials can be melted like cream and stretched as thin as the hairline. The printer uses these lines to draw the outline of the object based on the inputted or scanned blueprint firstly and then overlaps the lines upon the previous frame just like decorating the cake with
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 important and prevalent issues in healthcare discussed nowadays is the concern of the organ donation shortage. As the topic of organ donation shortages continues to be a growing problem, the government and many hospitals are also increasingly trying to find ways to improve the number of organ donations. In the United States alone, at least 6000 patients die each year while on waiting lists for new organs (Petersen & Lippert-Rasmussen, 2011). Although thousands of transplant candidates die from end-stage diseases of vital organs while waiting for a suitable organ, only a fraction of eligible organ donors actually donate. Hence, the stark discrepancy in transplantable organ supply and demand is one of the reasons that exacerbate this organ donation shortage (Parker, Winslade, & Paine, 2002). In the past, many people sought the supply of transplantable organs from cadaver donors. However, when many ethical issues arose about how to determine whether someone is truly dead by either cardiopulmonary or neurological conditions (Tong, 2007), many healthcare professionals and transplant candidates switched their focus on obtaining transplantable organs from living donors instead. As a result, in 2001, the number of living donors surpassed the number of cadaver donors for the first time (Tong, 2007).
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...
4D printing offers the ability to make things that literally pull themselves together. The technology could also create objects that last longer than their 3D-printed counterparts and adapt to specific conditions on command. 4D printing is relay about using a 3d printer to print self requfingering programmable material. For example you have a non-living object that can change his shape and behavior over time kind like a robot but no microprocessors, in fact something that looks like a plastic. Skylar Tibet’s, the man who came up with whole idea has gone even fodder; he created a programmable sheet material. It look like a plastic, that in combination with the water it could change the shape in the cube. And the cube is just a beginning. It will be a million of shapes. It could be so useful, not just on the Earth but in the orbit as well. This idea could change the world, and living on it. Imagine you could just print your furniture. An...
The Importance of Organ Donation Each day approximately 6,300 people die and what makes this haunting is that presently there are 83,513 people waiting for organs to be donated, yet each day 17 people die because they do not receive a transplant (http://www.donatelife.net/facts_stats.html). These statistics show that people who are waiting for organ transplants have a good chance at being saved and get what they need. The sad truth is though, because of the lack of people willing to donate organs, many people will continue to wait for organs to save their lives. ? Waiting lists of patients for organ transplants become longer as the need for transplantable organs increases? (Sheehy 1).
The first and biggest positive impact on engineering has been the use of Computer Numerical Control machines (CNC); computers were first introduced to these controls in the early 1970’s. CNC machines typically replace or work in conjunction with some existing manufacturing process. For example before CNC machines a person using a drill press to machine holes would have to do a lot of work for themselves. They would have to place a drill in the drill chuck is secured in the spindle of the drill press. They can then select the desired speed for rotation, and activate the spindle. Then they manually pull on the quill lever to drive the drill into the work piece being machined. As you can see, there are a lot of manual steps required to use a drill press to drill holes. While this way may be acceptable for a small number of holes or parts. However, as quantities grow, so dose the likelihood for fatigue due to the tediousness of the operation. There are also more complicated machining operations that would require a much higher skill level of the person running the machining tool. The CNC machining center can be programmed to perform this operation in a much more automatic fashion. Everything that the drill press operator was doing manually will now be done by the CNC machine, including: placing the drill in the spindle, activating the spindle, positioning the work piece under the drill, machining the hole, and turning off the spindle. CNC works from a source code made on a computer that you just save as a file on your disk and insert it into the machine. The code can be made using two different ways, the first is just understanding the code, and by using the notepad program on you computer, you can just type it right out. This is the easiest way for very simple process, which doesn’t require much code.
