You may have seen a 3D-printed rocket, a house, and even meat. But have you seen a 3D printed cheesecake?

你可能見過 3D 打印的火箭、房屋，甚至肉。但你見過 3D 打印的奶酪蛋糕嗎？

Researchers in New York have 3D-printed a seven-layer cheesecake.

紐約的研究人員們用 3D 打印機制作出瞭一塊七層奶酪蛋糕。

The Columbia University team is pushing the limits of food printing by using many different ingredients like Nutella and graham crackers.

哥倫比亞大學的這支團隊正在突破 3D 食物打印技術的極限，使用瞭多種原料，如能多益巧克力榛子醬和全麥薄脆餅幹。

The ingredients were first turned into paste, and then squeezed out of a syringe in thin lines, forming layers.

先把這些原料制成糊狀，然後用註射器擠出細線，構成蛋糕的層次。

The researchers say it could help people personalise their meals.

研究人員們表示，這可以幫助人們定制符合自身需求的餐點。

“When you’re able to kind of add each ingredient layer by layer, you can have a lot more control over what actually goes into the food. In that way, you can do a lot in terms of nutrition control by dialling in, ‘OK, I want this much potassium, this much calcium, this much Vitamin A.’ You know, and it will kind of learn from your habits too over time, recommend meals for you.”

“當你能夠一層一層地加原料時，你就可以更好地控制食物中的成分。這樣，你可以靠輸入成分的數值來控制營養攝入。比如，‘我想添加多少鉀，多少鈣，多少維生素 A。’ 這個系統還會慢慢瞭解你的飲食習慣，為你推薦食物。”

The team says it’s invented the use of lasers to cook food as it prints.

該團隊稱他們發明瞭在 3D 打印的同時用激光烹制食物的方法。

“On the roof, we shine a blue laser to cook and just texturise the top surface. We wanted to show how laser cooking can be used to texturise the food and also just to give you more flavour expression for certain parts of it. And you can control this type of heat to get browning versus broiling and baking. So, it’s a great way to kind of bring the whole story together, I think, to create one digital cooking platform that can do everything.”

“我們從食物上方向下照射藍色激光，來烹飪蛋糕，並把表層烤出質感。我們想借此展現怎樣用激光烹飪來增加食物的質感，同時也讓食物的特定部分有更豐富的味道。這種方式可以讓你控制溫度，烤出焦黃色，而從上方烤制和烘烤則做不到這一點。因此，我認為這是一種很好的方式，將各類烹飪方式集於一身，以打造一個無所不能的數字烹飪平臺。”

So, what does this cheesecake taste like?

那這塊奶酪蛋糕的味道如何呢？

Jonathan Blutinger, Columbia University
“It was pretty cool. I would definitely have it again, and I’ll say in terms of the general tasting experience, it’s different because each of the ingredients [is] layered on a really close level. So, when you bite into it, you get these waves of flavours that hit your palette at different times. So, it kind of made us realise you can localise the flavour in a really cool way.”

喬納森·佈魯汀格哥倫比亞大學
“味道很不錯。我肯定會再吃一塊，值得一提的是，就整體的品嘗體驗而言，3D 打印的奶酪蛋糕與平時我們吃的奶酪蛋糕味道不同，因為各原料間的層次非常緊密。所以，當你咬一口時，會有一波波的味覺層次不斷地沖擊你的味蕾。所以，這個體驗讓我們意識到，食物打印技術可以使餐點的特定部分具有特定的味道。”
