美文赏析 3D printers are very hot are being put to all kinds of uses,ranging from creating car models for movies to architectural① ,none of these ideas are as shocking as the one suggested by Anjan Contractor,who believes that they will be the key to ending world hunger. According to some experts,world population will increase to 10-12 billion by the end of this means that food will e very expensive and possibly,even out of reach,for billions of people. This is where 3D printing may save the thinks that the only way to solve the problem will be to equip every kitchen with a 3D printer and print out meals from tubes of powder and believes that these meals with a shelf life of over 30 years would result in less food wastage. More importantly,it would be easier to make food from things that we now do not consider edible②.A great example of that is the protein③ from experts believe that as the population grows,the supply is not going to be enough to feed believes that we could easily get the same protein from all this futuristic food may sound unappealing,the scientists believe that when faced with a terrible food crisis④,it will be very ed. While this may sound a little difficult to believe,Anjan seems to have convinced the scientists at NASA,who are looking for a solution to feed astronauts when they go on really long missions⑤,like the one being planned to Mars. They gave Anjan $ 125,000 to start building the first real 3D printer that creates the food. Anjan is not the only one with this group led by Professor Hod Lipson has been experimenting with this idea since 2011 and has even eeded in printing out cubeshaped creations from powdered milk and cookies with limited sugar!
