3D printers for the food moves into the kitchen

If kitchen tjansen seems a little long, so take heart, for soon there is help available 3D printers that can construct your favorite dishes.


If the cupboard is stocked with ice makers, coffee grinders, baking machines, fully automatic mincers and mandolin iron which nobody uses anyway, here's the ultimate kitchen equipment for the engineer who has everything: 3D madprinteren.

The idea has been underway for some years. The simple versions are chocolate printers that works on exactly the same principles as the famous 3D printers.

Instead of plastic or metal powder is heated up just before it is placed in layers, so we are talking about liquid chocolate is cooled down at the moment it hits the previous layer.

Another fun example of a homemade 3D printer to food, is Candyfab where the weirdest candy shapes can be created. Here's users in the development process, as the whole project runs as open source.

But the real madprintere who can create just the meal we sit and dream about - or would never dream of - is still slightly ahead. Here it is necessary to dream about new ways of preparing food. Without being able to explain the details of the actual cooking process so there is no doubt that the concept of molecular gastronomy gets a whole new meaning.

A good attempt to imagine such a comes from the Swedish giant Electrolux kitchen. Here, the annual design competition thrown a 3D printer off.

The idea is a bit like the eternal coffee brews that are up under the Christmas tree every year when there shall be found on gifts for Dad: You take an ampoule with the desired court (in the pictures from Electrolux is similar to most desserts) and stops the cartridge in the printer and out comes the product - or dessert, if you can call it that.

Chocolate Printer, built of Lego bricks
Another step up the fantasy scale find Cornucopia: Digital Gastronomy, drawing from MIT. The project has just started and if the result is just roughly holds in relation to the intentions and the stunning design images, so it probably will be able to lift an eyebrow or two.

Here refrigerated ingredients refilled ink cartridge similar container. Depending on the desired right, the contents of carefully measured quantities, mixed in a mixer.

The mixed ingredients are then sent into a chamber where it can be heated or cooled as needed. What you can do at such a madprinter, reports the story nothing about, but it is hardly a lasagna or roast beef.

The advantage of the MIT project would be to carefully measure out with the use of ingredients have full control over the nutritional value of the finished product.

For the really creative, here finally a chocolate printer with a Danish twist. It is in fact made of Lego.

Incidentally, there is little to suggest that we are even going to change our way of cooking. 40 years ago was the microwave proclaimed a revolution in the kitchen region, but many use it only for popcorn - bon appétit.

Are you in the market after a new printer?

Are you in the market after a new printer? Why not take the leap into the third dimension and make you a real 3D printer.
There is still a long way to 3D printers will be to buy the layman, but with objets latest copy Alaris 30, we are a little close-up. The printer uses something called polyjet Photo Poll Ymer jetting to make small objects with a oplsønging 600 x 600 dpi. You print out directly from your 3D program, and because the printer is so uncannily accurate, it can also create moving parts. Quite impressive.

I would recommend you look at the video HERE, which is a short demonstration of the printer, and afterwards in the check out the Official website.

Print a house with new 3D printer

3D printers can print models and other small 3D objects, but a finished house? A British company has now made it possible.

The British firm D-Shape has allegedly built the world's largest 3D printer that can print objects the size of a house. 3D printers are already in limited use in industry to produce models of such. cars or buildings, and they are also used in the art world.

3D printers based on inkjet technology builds the finished object up layer by layer, where each layer has approximately the same thickness as a piece of paper. The printers use a special powder which is very expensive, but work on finding cheaper materials.

D-Shape has been dealing with another problem - namely how to get the printer to print larger objects.

The big machine consists of an aluminum frame of six times six meters (can be extended almost indefinitely) that resembles an ordinary building scaffolds. And it's not completely wrong. Printer head moves back and forth on a bridge, mounted on the tripod and running up and down, back and forth in the racks.

Head inside the team 300 servo nozzles that spray a combination of sand and a special bonding material out with a speed of 0-500 mm / sec.

First, the architect designing his object in an ordinary 3D CAD program on your computer, then file is converted to STL format (stereolithography) and imported into the program that controls D-Shape printer head. The process starts from scratch and build the object up layer by layer.

D-Shape says that it takes 24 hours before the material is firm and dry. The machine itself takes a few hours to assemble and disassemble. The entire facility weighs five tonnes and uses 40 kW during normal operation.

The British producer imagines that the machine can be used to print everything from benches, sofas and bridges for gravestones.

A presentation of the unusual 3D printer can be obtained from D-Shape. Apparently not what giant printer to cost.

3D printer to build a heart

Scientists are working on a 3D printer that can build entire organs, which can be plugged directly into the body. It will give us something close to eternal life, says one of the developers of the Danish agency printer.


In the future, a 3D printer will be able to print a full, viable heart out, tailor-made to knock the blood around a heart patient's body. (Photo: Stanwhit607)
Future alcoholics could replace their worn-out living with a new one, created by their own stem cells.

Heavy smokers may have built a brand new, clean lung.

And anyone with heart defects get replacement parts or all of their heart with a new fabricated from scratch in a laboratory.

It sounds far fetched, but the method of producing agencies is even more incredible: They are printed with a "3D printer.

"To print the heart is the ultimate goal. When you can print out the heart, I would think that in theory could live forever, "says inventor Jeremie Pierre Gay.

The 28-year-old Frenchman has settled in Aalborg, where he is currently building a 3D printer that is reminiscent of an inkjet printer, with the difference however is that the 3D printer can print up in height and with many different materials.

Together with stem cell researchers from Aalborg University, he hopes in future to be able to print with living cells, which layers can be put together and replace vital body parts, which are already working hard to achieve in the U.S. (see video at bottom of article).

"Of course it is possible. It's going to happen sooner or later. I do not know when but it will definitely happen, "says Associate Professor Vladimir Zachar from the Laboratory for Stem Cell Research at Aalborg University.

'We want to see it in our lifetime'
DID YOU KNOW
565 Danes are waiting right now on a new body, but since only 12 percent of the population are enrolled donor register, there are many who do not undergo the vital organ in time.
This year alone 2008 died 56 Danes on the waiting list because they did not get an organ, and the figure has been rising in recent years.
"I think there will come a new biotechnology company that fits your stem cells. The day you'll need a new heart, they will create a customized heart to you. They look at the mistakes your heart is, repair it in their software and printer a new look. Then go to the hospital with your new, tailor-made heart and undergoing surgery, "says Jeremie Pierre Gay.

He guesses that it will take 20-25 years before you can print out tissue that can be inserted into the body and replace defective parts of bodies.

"Being able to print an entire body will take longer. I'd say 40-50 years, so it's not so distant future. I think we will see it in our lifetime. Life expectancy age will be much longer, "he predicts.

Bodies of printed layers
Inspiration comes from Professor Gabor FORGÁCS, who heads a team of researchers at the University of Missouri-Columbia, USA. Over there they have already started with the first experiments with 3D printers that can print with stem and literally build organs from scratch.


Americans' body print works on the same principle as an ordinary inkjet printer. First, the printer is a thin bed of so-called biopapir consisting of a special gel that cells can live in. Then bioblækken, which consists of living cells, drop by drop embedded in the thin layer of jelly. The cells are placed carefully in a pattern that scientists have instructed the machine to print later.

Once all the drops, each containing about 30,000 cells that are in place side by side in biopapiret, nature takes over. Cell droplets flow together, and the cells organize themselves to form tissues and blood vessels.

Once the first layer are grown together, added a new layer biopapir upstairs, and new droplets of cells printed into the gel. The process is repeated floor on floor as if you built a skyscraper until the tissue forms a three-dimensional structure. Finally dissolved biopapiret, the layers merge and back is the finished body.

They have printed veins and nerves
Gabor FORGÁCS and his research team believes that the method can be used to print any body and as the tissue formed by the patient's own stem cells, the body will in all likelihood, not repel it. But that day is many years away, but Americans have already shown that their 3D printer mastered the ability to build tissue.


To print a piece of a vein: First down biopaper and then printed cell drops down into a ring. The process is repeated layer by layer, and eventually grow the cells together to form the finished vein. (Photo: University of Missouri) "We have printed full biological nervous and blood vessel transplants. We are close to implant pieces of arteries in animals, and we've already done it with our nervetransplantater, "says Gabor FORGÁCS to videnskab.dk.

The U.S. researchers have founded the company Organize Novo, who in two years will do the same tests on humans, but it will take somewhat longer before the company can sell blood vessels and nerves.

"Because of the need to cultivate large quantities of cells and mature they printed designs, so they achieve the necessary biomechanical skills, it will take some time before these transplants can be mass produced for use in humans," says Gabor FORGÁCS.

Aalborg presses will build body printer
At Aalborg University puttering Jeremie Pierre Gay and stem cell researcher Vladimir Zachar with the idea of creating a similar 3D printer that can create human tissue. The method will be simpler than the U.S.. First they will print a support structure and then print the cells inside.

The goal is to print simple body parts such as cartilage, bone, muscle and adipose tissue. So far, however, the project failed because it needs money to hire a PhD student to work with it.

But whether the printer body is developed in the U.S. or Aalborg, Vladimir Zachar sure that 3D printers will be used to build body parts out of cells in the future.

"It is very likely. We have the technology to do it. We do not know yet, but it is very possible. Especially when it comes to simpler tissues, "he says.
