3D printing is becoming more and more popular. We are now able to print things we need very quickly and easily using 3D printers .But can you imagine print food? Some scientists are trying to change the dining experience by doing this. They hope that having a 3D printer in the kitchen will become as common as having the microwave oven (微波炉) . Scientists say that it will be quite easy: you simply have to select a recipe (食谱) and put the raw (生的) "food inks" into the printer. You can also read the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and nutritious meals. Printing food could also help people who suffer from dysphagia (a swallowing disorder). They could program the printer to print softer versions of their favorite food so that they would not have trouble in swallowing them. However, some people think that a future of 3D-printed food would be a disaster. It could take away many jobs, including those for growing, transporting and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes could be printed from a raw "food ink". Likewise, traditional cafes and restaurants might lose business.Also, there are concerns about the nutritional value of the printed food:Is it really possible to get the nutrients we need from the food-based ink and gels. What’s more, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and that meals can be created at the touch of a button.
