Do you know that there's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale.
Food production
With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. —it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.
Sustainability
According to a new study, the global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. 3D food printing could probably contribute to the solution. 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.
Nutrition
Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."
Despite recent advancements in 3D food printing, the industry has many difficulties to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad.
A. Challenges
B. Opportunities
C. And the industry isn't stopping there.
D. Sustainability is becoming a necessity.
E. Future 3D food printers could make processed food healthier.
F. Here are some new ways to produce 3D printing.
G. Not everybody can do that.
Clara Barton，founder of the American Red Cross，gained worldwide honor for her dedication to easing human suffering and earned the nickname “Angel of the Battlefield.”
