3D printed Pizza

Posted May 28, 2013 By Hanna El Alfi

 

 

Mechanical engineer Anjan Contractor is working on a printer that would use ”basic ‘building blocks’ of food in replaceable powder cartridges,” to make foods. The pizza printer will first print a layer of dough, which will be cooked while being printed, before mixing tomato powder with water and oil to print a tomato sauce. The topping for the pizza will be a nondescript “protein layer.” -The Verge. Pizza is just an example of what the 3D printer can do–likely because it seems easy to ‘print’ being flat and mostly uniform–but the printer will be able to do all kinds of different foods. Currently the device is in development for use by astronauts on long-distance journeys (hence the NASA funding, $125,000,) but eventually the developers hope to use 3D printed foods in impoverished areas: the printers would be able to easily create food with little to no waste in a small space with little labor.

3D Printed Bikini

Posted May 27, 2013 By Dana Saba

The N12 is the first 3D printed bikini from Continuum Shapeways Shop. The 3D printed items of clothing have been completely experimental and not for sale, however this 3D printed bikini is wearable and available to buy. “The bikini’s design fundamentally reflects the beautiful intricacy possible with 3D printing, as well as the technical challenges of creating a flexible surface out of the solid nylon. Thousands of circular plates are connected by thin springs, creating a wholly new material that holds its form as well as being flexible. The layout of the circle pattern was achieved through custom written code that lays out the circles according to the curvature of the surface. In this way, the aesthetic design is completely derived from the structural design.” – Mary Haung, Continuum Fashion.

Within the patterning of the 3D bikini, geometry is utilized to point out mathematical specifics for the circles. The pattern process starts off with a curved surface where the circles are placed with in the borders of the bathing suit. The placement of these circles are in a manner where they reach as close to the edges as they can and their sizes are specifically engineered so that the allow that and fit the confined degree of curvature. The areas with a larger degree of curviness receive smaller circles than relatively flatter areas that receive larger circles. Furthermore guaranteeing elasticity and efficiency where necessary.

The main objective behind the circle pattering is allowing the system availability to any surface and any size. Moreover the same algorithm can be used to produce other types of 3D printed clothing and even more it can be customized for a specific person with the use of a body scan to specify the fitting.

The bikini is named after the material in which it is 3d printed which is Nylon 12 (N12). It is not only waterproof but also the first swimsuit that gets more comfortable when it is wet.

3D printing to save a babies life.

3D Printing saved babies life-url

Brief description- An operation in the US was carried out that included creating a breathing device using a 3D printer to save a babies life. The baby, Kaiba Gionfriddo was six weeks old when his parents begged for help, after he collapsed at a restaurant. For the next few months, he would stop breathing often and would have to be resuscitated practically everyday. The print was necessary because Kaiba was born with the main arteries of his hart and lungs misplaced, and they were blocking his windpipe causing tracheobronchomalacia, a rare condition that most children grow out of, but his was a severe case. Doctors worked with a biomedical engineer at the University of Michigan to create a device that was implanted in Kaiba’s chest, sort of like a vacuum cleaner that acted as a splint that would keep his airway open. Three weeks later, he was taken off the ventilator and has not had any breathing troubles since, meaning this 3D printed splint saved his life.

A quote from Professor Hollister says “Kaiba’s case is the highlight of my career. To build something that a surgeon can use to save someone’s life – it’s a tremendous feeling.” I think this is an amazing way to use 3D printers, as they can now save lives. By printing this splint, the baby was able to breathe and therefore survive, whereas without it, Kaiba would have certainly died. Though Kaiba’s case was an emergency, being able to produce parts to save one’s life like that is any doctors dream, and there are huge benefits to being able to do that because if you can produce a part like that, soon they’ll figure out how to produce other parts. Who knows, in the future we may be living double what we are now if we can produce another heart, lungs and liver. Having said that, there are also huge ethical issues that go along with the bonuses of 3D printing parts. If we are able to print all of these parts and save people, we are kind of going against what we have always known, and don’t know what effects it may have. People need to die in order for the population to not get any worse, dying is just a part of life. But now being able to 3D print parts means there can be lots more people saved, which for them may be good but in the long run it will be negative for the society.

3d printed artwork

Posted May 23, 2013 By jh_park5869

<Bloom> by Michael Eden

The artwork above uses an unbelievably complex design formed by a cylinder pattern. Using the cylinders Eden has made grail like object that is quite impressive. Although the design itself is already amazing, but what’s more impressive is the structure of each piece that was used to build this art work. It is in’t just a simple addition of thousands of cylinders, but a completely planned organization of cylinders that are built in maybe about 4~5 pieces in total. In history many craftsmen and sculptors have shown exceptional skills in building, but no one has ever been able to create such detailed and complex structures. In fact many people have never even though of building such models knowing that it is impossible by human hands. 3D printing in my opinion has brought “impossible” to the art world. Michael Eden used a 3D printer to make his art work “Bloom”, and although not a renown art form yet, it is definitely a strong candidate of future artwork.

3D printed bones

Posted May 23, 2013 By 14melghamry

3D printing is slowly being used more in society. At the dawn of 3D printing’s creation, one could only print simple shapes, and possibly a mechanical part. Now, one can print countless things such as body parts, guns, food, and even clothes! This incredible innovation has brought many advantages to society, and many advancements in fields such as medicine, and science. This manufacturing process has no limits, and it’s abilities keep growing every day. One recent 3D printed item is the bone. On march 4th, 2013, the first skull replacement surgery took place. In this surgery, the surgeons replace the damaged areas of the skull, with 3D printed parts. Although these bones are fully artificial, they still have the similar strength, and properties of a real bone, and can also function exactly like one. A man once had 75% of his skull 3D printed as a result of excessive damage during an accident. The ability to 3D print bones will be able to save hundreds of lives and it will also make treatment much easier and cheaper. Instead of a transplant, robotic part, or even an amputation, people can simply receive the needed bone through 3D printing. The 3D printed bones and other organs also help hospitals save money, since it is much cheaper than a normal transplant. In addition, these 3D printed bones can be easily customized for different patients and their ergonomic needs. This makes the availability much higher, and therefore, it becomes easier to to receive such treatment. From hearts, to bones, 3D printing can evidently be used in medicine in the future. It will absolutely change the way patients are treated, and it will also make the target market much bigger since it is more affordable for people. Although this is a very interesting invention, it still needs to be perfected since there are many factors that were not considered. Factors like the time it can be left in skull-Will the patient need replacements every few years?

The 3D printing of bones exemplifies the amazing abilities of 3D printing, and it’s various inventions in the future.

3D Printing- Food- Saving Lives

Posted May 23, 2013 By aminamin

3D printing is a process of making three dimensional solid objects from a digital model, and performed by a materials printer using digital technology. 3D printing has come up with a way to end hunger. 3D printing can end hunger by creating 3D food.

null

3D printed food will affect mankind, as it will feed everyone. According to the “contacter”, 3D printing meanms the end of food waste. If ever the worlds population reaches its peak, the people will not be able to live due to hunger. However, due to the 3d printed foods, people will be able to live without hunger. The machines will have powder that is shelf stable for up to 30 years, having all the nutrients.The 3D printing affects the society socialy as not only the rich will be able to never face hunger, but also the poor. The 3D printer will provide the poor with food at a lower price.

Not only will3D printing help the people from being exposed to hunger, it will also save lives. On May 22nd 2013, a baby was saved by 3D printing from tracheomalacia, which is a diease that causes the windpipe to collapse. After being given the permission the doctors were allowed to use the 3D printed part in order to save the baby.

This shows a future of advancement in medicine. 3D will help save lives that are suffering. This as said before, will lead to an adfvancement in medicine, and save many lives, moreover, it will make the process of organ donation faster as the patient will not have to wait for an organ donor, instead the organ can be 3D printed.

In conclusion, 3D printing is an excellent invention, as in the soon future it will be saving lives due to organ donation and prevention of hunger.

3D Printing Food

Posted May 23, 2013 By Miro

New 3D prototype has been made by Janne Kyttanen, it is capable of printing pasta, breakfast cereal and burgers to demonstrate advances in 3D printing and how it could transform the way we eat. There have been chocolate printed. In order to show that it is possible to print food, some samples of 3D models in plastic were made of pasta and burgers. It is only a matter of time before technology enables us to print molecule in combinations that produce tasty meals. So far the 3D printers that we have today only enable us to solidify matter. It’s just atoms and molecules and with a better advanced technology, we will be able to just move molecules or move atoms. However we are still far away from 3D printing burgers at home. It will be an amazing feature that we will be able to have and make because it will be fast and everything will be on a computer. Food is the next generation in 3D printing. So far the pasta isn’t made of pasta but of plastic, and the point of this was to show people that it is possible. Printing in chocolate is already possible. There is also creativity involved in the 3D printing of food, because once it will be possible to actually print using food, people can be creative and print all sorts of things. The time where 3D printing food will be mainstream depends on what kind of financial push it is given.

Ergonomics – Chairs

Posted May 23, 2013 By Wadood
Ergonomics is a branch of science that spawned from engineering, physiology and psychology and it seeks to improve the synergy between the objects that humans use and the humans that use them. It ensures that the restrictions that humans are subject to can be countered with design solutions. One important product that utilizes ergonomic design in its manufacture is the ergonomic chair. These are chairs that are designed to seat most users extremely comfortably as it fits their body. Discussing the benefits of the ergonomic chair will allow us to differentiate between it and regular chairs.
One of the main benefits of using ergonomic chairs is that they fit all kinds of body frames and provide suitable support that can allow you to sit for multiple hours without discomfort or pain and this can be beneficial to people who spend a lot of time on the computer for work or recreation.
There are considerations that must be taken into account when purchasing an ergonomic chair. The most immediate concern of anyone willing to buy an ergonomic chair is the price. It takes years of studying body mechanics, movements and postures to develop a good ergonomic chair design and therefore the price is incredibly high; some ergonomic chairs sell for more than $300 but they can also be as low as $70.

Ergonomic chairs also minimize safety risks that are constantly present in the workplace or even when you sit down for too long. These chairs are meant to seat people of different body frames and sizes with minimal risk of injury, pain or discomfort. Sitting on regular chairs may seem comfortable to many people  but it actually puts incredible stress on the back as the full weight of the body is supported by the buttocks whilst also exerting pressure on the invertebral discs in your back. This is because regular chairs were not designed with body mechanics being taken into account. On the other hand, ergonomic chairs alleviate all the above symptoms as they were designed to maintain comfort and prevent injury whilst sitting. This results in better health, safety and productivity in the workplace.

3D printed car- Chayse Lavallais

Posted May 23, 2013 By cmlav14

One idea that 3-d printing is being used for is the 3-d printed car. The Urbee 2 is a car, which is being mad entirely out of a 3-d printer. The car is very light from the materials that it uses from the printer, which is called ABS plastics. This means it will have a very efficient gas mileage, hence a positive impact on the environment. The prototype of this car so far only weighs about 1200 pounds. The car is produced with the concept “lights of construction”. This is the idea he just uploads the parts to the printer and leave as it is produced. It takes about 2500 hours to make an entire car. Safety is also considered for the car, which can use this light material to make just as qualified parts. As well, the car will have a metal cage around the driver, similar to a NASCAR, and putting added shock absorbers to help with any sort of impact. The plastic can give each part a specific thickness and shape at each spot, keeping the durability. At the same time it is also light, which makes it more efficient.  As a result of all this, the car is very aerodynamic, only having .15 coefficient of drag while driving.  For the engine, it is going to be made from metal instead of plastic. However, it will be made with a hybrid engine, which plans on using an electric engine while the car is going between 0-40mph, and changing to a diesel engine on faster speeds.  One concern is that many of the parts are one big piece. This means if a part breaks, you will have to replace the whole giant part, which would be expensive. The car overall will cost about 50,000 dollars. However, it will not be available to the public for a while.

3D Printing: Piracy

Posted May 23, 2013 By omar.elgebaly

3D Printing is becoming a new and more advanced technology and is slowly taking a bigger role in the world. However, one of the main concerns of 3D printing today is piracy. Because files are easily copied, users can easily reproduce products as long as they have access to a 3D printer. Today, many torrenting websites make it accessible to download games, music, and movies illegally. However in the future it can all change. The piratebay.com released the statement:

“We believe that the next step in copying will be made from digital form into physical form. It will be physical objects. Or as we decided to call them: Physibles. Data objects that are able (and feasible) to become physical. We believe that things like three dimensional printers, scanners and such are just the first step. We believe that in the nearby future you will print your spare parts for your vehicles. You will download your sneakers within 20 years.”

This has some extremely adverse ethical implications to it. As the prices of 3D printing falls, the companies that produce these pirated products will also lose profit. As you can see what happens today with torrented music, games  and movies, people are going to generally take the easier, cheaper way. In the future, this could have some huge implications on major companies. Imagine when 3D printers get so advanced to the point where they can print computers. It could make extremely expensive things virtually free. There is not much a company can do about this as encrypting the files will not fully prevent illegal distribution. These companies will become powerless in the future. With the ability to print everything from clothes to bicycles in the future, everyone is going to take the free route. If that happens, it can lead to a serious collapse in economy as we are a largely capitalistic society today. Before implementing and advancing 3D printing, it is important to address the issue of piracy extensively.
