Researchers at Columbia University in New York have created a 3D printer that makes cheesecake.
日前，纽约哥伦比亚大学的研究人员发明了一种可以制作芝士蛋糕的3D打印机。
A retrofitted, off-the-shelf 3D-printer was used; the printing head could pick up any of the seven food "inks" to add to the slice.
该研究使用了一台改装后的3D打印机，打印头可以将七种食物“墨水”中的任何一种添加到蛋糕上。
A blue laser was used to brown and crust the top surface of the graham cracker paste, Jonathan Blutinger, the lead author of the study and an engineer at Columbia's Creative Machines Lab in New York, told USA Today.
该研究的首席作者、哥伦比亚大学创意机器实验室的工程师乔纳森·布鲁廷格在接受《今日美国》采访时表示，蓝光激光器被用来使蛋糕表面的全麦饼干浆变得金黄酥脆。
Until now, most 3D-printed foods were made with uncooked ingredients, the researchers say.
研究人员称，迄今为止，大多数3D打印食品都是使用生食材制作的。
But in research published Tuesday in the journal npj Science of Food, the engineers describe how their 3D printer made a cheesecake from seven ingredients: graham cracker, peanut butter, Nutella, banana puree, strawberry jam, cherry drizzle, and frosting.
但在周二发表在《npj Science of Food》期刊上的一篇研究中，研究人员描述了他们的3D打印机是如何使用全麦饼干、花生酱、能多益牌巧克力酱、香蕉泥、草莓酱、樱桃糖浆和糖霜这七种原料制作出芝士蛋糕的。
The final result "tasted pretty sweet -- in more ways than one," Blutinger said.
布鲁廷格称，最终的蛋糕成品“尝起来香甜可口”。
"The cheesecake is the best thing we can showcase right now, but the printer can do a whole lot more.
“这款芝士蛋糕是我们目前能展示的最好的产品，但3D打印还可以做得更多。
We can print chicken, beef, vegetables and cheese. Anything that can be turned into a paste, liquid or powder."
我们可以打印鸡肉、牛肉、蔬菜和奶酪。以及任何可以变成糊状、液体或粉末的东西。”
He expects restaurants will begin using food printers in the next few years, "for digital gastronomy and one-off food add-ons to class-up a dish or make something aesthetically appetizing."
他还预计，餐厅将在未来几年内开始使用食品打印机，“用于制作数字美食以及一次性食材附加品，以提高菜肴的档次或使菜肴更具美感。”
When the first ones arrive, perhaps in five years or so, they will likely be less than $1,000, Blutinger said.
布鲁廷格表示，第一批3D食品打印机产品可能在未来五年左右推出，其价格可能会低于1,000美元。
