Editor's note: 3D printing technology has always attracted attention. 3D printed pistols have just caused a "commotion", and now there is something new that has become the focus of media attention-3D printed food. Anjan, a mechanical engineer who specializes in 3D printing, is currently working on this project. If you want to send people to Mars, you must prepare enough food for this task that may last for several years, and use a 3D printer to cook for astronauts. Does it sound incredible, and science is currently being studied. NASA develops 3D food printer According to foreign media reports, NASA has funded the development of a 3D food printer that can print food in boxes filled with oil, protein powder, and carbohydrates. The material in the cartridge may come from insects, grass and algae. This idea sounds out of reach. However, NASA has provided 3D printer manufacturer System and Materials Research Corporation (SMRC) with a six-month funding of $ 125,000, requiring it to develop a general-purpose food synthesizer. This food synthesizer is similar to the "replicator" that appeared in the popular TV series "Star Trek". In Star Trek, the crew of the Enterprising team used a replicator to copy their favorite food. The reason why NASA funded the development of a food synthesizer was to reduce the difficulty of transporting food in space. Anger Cotrato, founder of SMRC, believes that this device will help solve the global food crisis. After the global population reaches 12 billion, the pressure on human food sources will reach an alarming level. Cotrato said in an interview: "I and many economists believe that the current food system cannot fully feed 12 billion people. Therefore, we must change our perception of food." When printing, the 3D printer first prints a layer of dough, and at the same time prints and bake by heating the plate at the bottom of the printer. After that, the printer printed out the tomato base-also kept in powder form-and then mixed with water and oil. Finally, the pizza is covered with a layer of protein. The source of protein can be anything containing this nutrient, such as insects or algae. Space food printer is still under development NASA hopes to develop a food processor that can be used in space to meet the food needs of astronauts on long-distance interstellar travel. However, researchers hope that this food printer will not only meet the needs of astronauts, but also contribute to alleviating the world's food shortage. The goal of this project is to "print" nutritious and delicious food using the most basic materials. According to the ideas revealed so far, the basic working principle of this 3D food printer is similar to that of a traditional printer. It uses three to four basic materials similar to the ink in the printer to print a variety of delicious food. The software system of the 3D food printer adopts the open source method, which is convenient for researchers to develop various recipe programs, and the hardware system is similar to the prototype 3D printer, which supports a variety of hardware terminals. The design concept of the 3D food printer is to print out various delicious foods with the most basic materials. Although human ingredients are varied, all foods can be classified as the four most basic nutrients: water, protein, carbohydrates, and inorganic salts. The researchers tried to print out all kinds of food using these four most basic nutrients. Future 3D printer space cooking for astronauts NASA spokesman David Statz wrote in an emailed statement that the current aerospace food system to deal with missions such as the arrival of Mars that requires a long battle is not only insufficient in nutrition but also unacceptable. At this stage, astronauts carry pre-packaged food, that is, instant food for military use. This kind of food is not only bad in taste and variety, but also heavy. It is envisaged that the food produced by the 3D printer can be customized for each astronaut's nutritional needs, health status and taste. Systems and materials research companies make pizza their first goal. The reason for choosing pizza is that it contains many nutrients and flavors. At the same time, the multi-layer structure of pizza is the key to using 3D printing technology. The system and materials research company proposes that all nutrients made into astronaut food, such as protein and carbohydrates, will be stored in boxes in powder form. When the astronauts choose a good recipe, all necessary ingredients will enter a compartment, mixed with water and oil. The above mixture is then heated and sprayed onto a hot base. Food is formed layer by layer on this base until fresh "out of the oven". For novice bakers, choosing the right baking tools is the first lesson on the road to baking. In the end, which tools must be bought, which tools chicken useless? We have prepared the necessary tools for novice bakers.
