NASA Puts Up Cash To Create Pizza-Making 3D Printer

There’s nothing like months aboard the International Space Station to get an astronaut to hate space station food – one can only have so many servings of freeze-dried ice cream. In an attempt to not only expand the menu for Earth orbiters, but to also bring us one step closer to every Trekkie’s dream of a food replicator, NASA is funding a project that is aimed at creating a 3D printer to serve astronauts up some pizza.

“Earl Gray, hot…and extra pepperoni on the pizza.”

NASA has enlisted the help of mechanical engineer Anjan Contractor at Austin, Texas-based Systems and Materials Research in the form of $125,000 to build a 3D printer that makes pizzas. Contractor has already made a proof-of-concept printer able to print the chocolate chips onto a cookie. To print the pizza, he plans on first printing out the dough and letting it cook while printing out sauce and toppings.

The pizza printer won’t be a simple, automated layering of sauce and anchovies. It will be a true 3D printer, fabricating the different toppings from their component ingredients. This is important in space where the shelf life of food needs to be really, really long. A “digital recipe” will be used to combine powders, containing proteins and carbohydrates, and oils to create foodstuffs that have similar structure, taste, smell and nutrition as the real thing.

“The way we are working on it is,” Contractor explained to Quartz, “all the carbs, proteins and macro and micro nutrients are in powder form. We take moisture out, and in that form it will last maybe 30 years.”

That’ll definitely come in handy for a trip to Mars, until we can terraform the planet, of course, when fresh vegetables will be aplenty. But astronauts aren’t the only ones who stand to benefit from printing food.

A pizza is an ideal food for a 3D printer to tackle. It has a variety of ingredients arranged in layers. Contractor hopes to use the money from NASA to build the food-printing device by the end of the year. The following is a video of his prototype that can print chocolate on a cookie.

The idea of printing food has been around for a while now. In 2011, a group at Cornell created a printer that prints chocolate, cheese, scallops, celery, even turkey. But rather than use the layer-by-layer fabrication method that has come to define 3D printers, their food is made by layering ingredients squeezed out of tubes. And just last month a scientist in the Netherlands printed an entire burger, although with its $325,000 price tag it’ll be some time before our corner burger shops adopt the technology.

One can envision a day when 3D food printers will enable the long distance transmission of digital recipes, so Mom can “cook” you your spaghetti just the way you like it even if you’re miles – or planets – away. Ray Kurzweil predicts that, in the future, information will become a major commodity to be bought and sold. Recipes, furniture designs, unique toys – the blueprints for anything that can be 3D printed, instead of the finished products themselves – will compete on the open market. But the printers have to be built first. And who better than NASA to push even the culinary envelope? Hopefully their can-do attitude results in a delicious pizza with the workings, and eventually we can all eat like Captain Picard.

    Nice article, but I believe the term is pizza with the “works,” not “workings.” :)

    I don’t really see the advantage of 3d printing a pizza vs. 3d sketching (dropping the ingredients by hand). I mean, so what if a certain ingredient is a few milimeters or centimeters to one side or the other?

      the point is that it creates the ingredients themselves combining nutrients. I think a good point here is that we will be able to control exactly what we eat.

    Very nice article. Hungry? Print a Chocolate. Food Engineering, Chemical Engineering, Drying of “solids” Transport Phenomena, Momentum Transfer, Navier Stokes Equations and Non-newtonian Fluids, Professor J D Seader maybe you must include this example in your book Separation Process Principles Jorge Gamaliel Frade Chávez

    3d printing technology more mature than just come out , the average consumer to understand its function more and more deeply, to see a 3d print reports that have been put in the military field, responsible for the production of large originals. 3d printer compared to traditional manufacturing machinery greatly shorten product development cycles, improve productivity and reduce production costs.The high price of China 3D printer LXMaker launched new products.Interested in 3D print can log onto the http://goo.gl/6l6j29 or http://goo.gl/2wt6LU view details.

    Well, although making food for astronauts by additive printing is certainly an interesting concept I’ve got some reservations about it. First, would it really be tasty like the food we eat everyday? Secondly, will they make it available to the general public? I think the answer to both questions might be in the negative.
