Imagine coming down for breakfast. You don’t pop a piece of toast in the toaster or boil an egg. Instead, you stick a cartridge in a printer. A minute or two goes by. Then you’ve got a freshly printed banana and a muffin.

The printed breakfast is several steps closer to reality for the average consumer.

"Food printing may be the 'killer app' of 3D printing." That's according to Hod Lipson. He's led the creation of the new printer. "It's completely uncharted territory." 

Lipson is a professor of mechanical engineering at Columbia University. He has been studying 3D printing for nearly 20 years. He is working on printing things like plastics, metals, electronics and biomaterials. His work on 3D food printing came out of his research on printing complete 3D robots. They could, in theory, “walk off the printer.”  

What does it take to achieve something like this? A printer must be able to print with many materials at the same time. Lipson experimented with making multi-material printers. He noticed the students in his lab were beginning to use food as a test material.

“They were using cookie dough, cheese, chocolate, all kinds of food materials you might find around an engineering lab,” he says. “In the beginning, it was sort of a frivolous thing. But when people came to the lab and looked at it, they actually got really excited by the food printing.”

Lipson and his team began to take a more serious look at just what they could do with food. There are two basic approaches to 3D food printing, Lipson explains. The first involves using powders. They are bound together during the printing process with a liquid such as water. The second approach is extrusion-based. It uses syringes that deposit gels or pastes in specific locations.

Lipson’s prototype involves an infrared cooking element. It  cooks various parts of the printed product at specific times.

“We’ve used all kinds of materials, with different levels of success,” Lipson says. 

“Sometimes the materials are conventional. Cream cheese is something students like to work with a lot.”

They’ve also recently collaborated with a New York culinary school. They let chefs play around with the prototype.

“They kind of broke the machine by really pushing it to its limits,” Lipson says. 

“One thing we’ve learned is printing in cream cheese is very easy. But printing in polenta and beets is very hard. It has these granules in it.  So from an engineering standpoint it’s much more challenging.”

It’s also difficult to predict how different foods will fare when combined. It’s easy enough to create recipes based on single items like chocolate. Those properties are well-established. But when you start to mix things together the mixtures may have much more complex behaviors. 

Another challenge is figuring out when to cook what during the printing process. If you’re printing a pyramid of salmon and mashed potatoes, the salmon and the potatoes will need very different cooking times and temperatures. The team is tackling this problem with software design. They are working with computer scientists to create software that will predict what the final product will look like.

The printer Lipson's team has made is not the only food printer to be developed in recent years. There are products like Hershey’s chocolate-printing CocoJet or the Magic Candy Factory’s 3D gummy printer. They are both for single-ingredients. This limits their use for the general public. Lipson’s printer is unique. It is able to handle many ingredients at once and cook them as it goes.

Lipson sees the printer as having two main uses for consumers. First, it could be a specialty appliance for cooking novel foods. These are difficult to achieve by any other process. You could print, say, a complex pastry designed by someone in Japan or a recipe you’d never have the expertise or equipment to make by hand. Lipson says he could imagine digital recipes going viral. He can see them spreading across the globe. 

The second use is about health and targeted nutrition. People are already increasingly interested in personal biometrics. This includes tracking their blood pressure, pulse, calorie burn and more. They do so using cell phones and computers. In the future, it may be possible to track your own health in much greater detail such as your blood sugar, your calcium needs or your current vitamin D level. The printer could then respond to those details with a customized meal. This is produced from a cartridge of ingredients.

“Imagine a world where the breakfast that you eat has exactly what you need that day,” Lipson says. “Your muffin has, say, a little less sugar, a little more calcium.”

When might the printer might be available to consumers? Lipson says it’s more a business challenge than a technology one.

“How do you get FDA approval? How do you sell the cartridges? Who owns the recipe? How do you make money off this?” he says. “It’s a completely new way of thinking about food. It’s very radical.”

A recent redesign of the prototype may bring the product closer to being something the average consumer would accept. Previous versions of the printer were very high-tech and full of tubes and sticking-out nozzles. People had a hard time imagining it on their kitchen counters.

Then, one of Lipson’s students named Drim Stokhuijzen, an industrial designer, completely redesigned the machine. He gave it the sleek look of a high-end coffee maker.

“His design is so beautiful people are saying for the first time, ‘oh, I can see the appeal of food printing, this is something I might actually use,’” Lipson says.

Although Lipson doesn’t think 3D food printing will replace other cooking techniques, he does think it will change the kitchen.

    This passage is about 3D printing food. 3D printing food can be very helpful For classes that could use food for experiments. using a food printer in the mornings for breakfast would be so cool and it would save a lot of time for kids that sleep in. some people might think that this wouldnt be a good thing because it would be better just to make the food but i think it could be very helpful to have this 3D printer in a house. Having a printer can improve peoples lifes just by saving time.

    That's crazy how you can 3D print food. First off will the printer take a long time to make the food? If you're printing food for the morning would you have to start printing the food at night? I think it would be a bad idea to print food it takes the fun away from just cooking food. Does it not create as much pollution as other stuff using electricity? If it doesn't then that would be a good thing.

    This "3D printer" is a bad thing for people who can't afford it and people quickly lose their jobs due to this machine. For example a worker that works somewhere that sells food but doesn't get paided much that would be a huge problem. This 3D machince printing food is a very much like bad thing in case you haven't notice this food printing machine will put people through starvation. The food printing machince makes people think they aren't needed. The 3D printing machince can't even go over its own limits and make differ food so basicly people are wasting their own money through just a printer.

    This is very cool, and close to advanced stuff.

    the materials and money for the food are probably expensive if your going to make a meal for your family or even just yourself

    If I could 3D print my own breakfast, I would 3d print pancakes. In my opinion pancackes are the best breakfast food ever. I don't like the thought of 3D printing it because I would imagine 3D printing any food would be bad for you. It might have plastic or some unknown gel in it.

    This article is about the idea of 3-D printing food. Personally I don't think this a good idea because it takes away the fun of making the food home-made. I might of not liked the idea, but the article was well written. I liked how he explained the idea of the 3-D printing and how it is created. He really talked descriptivley about the 3-D printing.

    I think that 3D printing is cool and good idea but i personally don't completely support it. I think that it will be too complicated and easy to accidentally brake it. I think that making the meals yourself is much easier and more fun. Also if there were printing machines alot of people would loose there jobs if they were bakers or chefs.

    In response to "3D print your breakfast," I agree that having a 3D printer to print you breakfast would be interesting. One reason I agree is that this is a relatively new technology, so people would be excited about it. Another reason is that you could have your food item quickly. It says in the article, "you could do more things like fix your hair, instead of preparing your breakfast. A third reason is you can have nicer dinners for a lower cost. Even though it is not in the near future, the machine will eventually pay itself back in the price of food costs.
