New technology aims to change the way we order, buy and eat meals
Alex Lightman is a futurist who spends a lot of his time thinking about what new food technology will mean for the way people eat. And he believes one of the surest things about the future of 3D printed food is that it won't work the way people imagine it will.
"People think that things are going to be automated and scaled, but that's not true," he said. "The truth is that people really misunderstand how it's going to work."
Lightman serves on the advisory board of Natural Machines, a Barcelona-based company that is getting ready to launch a new 3D printer called Foodini that will allow amateur home cooks and Michelin-star chefs to manipulate food in ways that weren't previously possible - at least commercially.
The machine, which will be released later this year, can produce almost any shape and process many different inputs. Homemade pasta of almost any shape and size, perfectly packed veggie burgers, carefully portioned, identically shaped servings of mashed potatoes - these things will all be easy tasks for the new food toy.
"We already have a number of restaurants, including national chains, and Michelin-starred chefs who have expressed interest," said Lynette Kucsma, the founder and chief marketing officer of Natural Machines.
Like so many innovations before it, 3D printed food will give rise to all sorts of projections - some truer than others - about what the future of food will look like.
One vision is a dystopian future in which much of our food is mass produced by some later mutation of current 3D food printing technology. But there's another possibility: that by taking different ingredients, combining them together and producing food to exact 3D dimensions, the future of food could be wildly creative - and fun.
"The key word here is customisation," said Lightman. "I really don't think people quite understand how much control they will have over the things they will be able to order."
Once the price of 3D printers has fallen enough that companies like Starbucks or McDonald's have them at stores around the country, and the machines are advanced enough to handle a nearly endless list of food items, traditional menus will serve only as inspiration.
"Eventually, you'll be able to get a custom meal that looks exactly as you want it, that meets the most ridiculous and precise requirements," said Lightman.
Others familiar with the technology feel similarly about its promise. Hod Lipson, a professor of engineering at Cornell University who runs the Creative Machines Lab, has written an entire book about 3D printing.
"It's incredibly disruptive, but not in a way that replaces production," said Lipson. "You'll never see Doritos made with 3D printing, because the production process is too slow.
"Imagine a future where you could dial in what you want from, say, a granola bar or cookie or chip," said Lipson. "That's what we're going to have."
3D printing will eventually allow not only for ingredient or portion-specific customisation, but calorie-specific requests. Two friends, wanting the same dessert in different size, could order precise calorie portions.
Foodini, as it will be introduced this year, won't allow for such specificity. Nor will it cook the raw ingredients it moulds into ravioli, or hamburger patties. (The next generation of the machine, which won't be introduced for another few years, will.) But it does have Wi-Fi-connectivity, which Lipson argues could shape food in the way the iPod has shaped music.
"If people are sharing recipes online, and a recipe goes viral that can be replicated by merely the push of a button, they will spread incredibly quickly," said Lipson. Eventually, he suggests, there might be restaurants without cooks, waiters or cashiers - only iPads with thousands of recipes to pick from and 3D printers to meticulously process each order.
