From Tsinghua, two "pancake man" 3D printing can also be so grounded
At noon on Saturday, Beijing’s Jianwai SOHO is still a lively place.
Some people who want to find a traditional food mat in the CBD go into the "good luck", call a hot pancake, and take it away.
Boss Wu Yili will happily introduce the ingredients of their family to the guests who came to the store for the first time: healthy and good oil, fresh earth eggs, mustard in Wujiang Fuling... The pancakes are packed, he will also say: Please be hot Eat, it won't be crisp for a long time.
The guests who rushed into the store and hurriedly left did not know. This gentle and thoughtful boss graduated from the Software College of Tsinghua University in 2007. He worked at IBM and gave up a million-year salary to start a business. He wanted to be a “pancake brand that affects 100 million peopleâ€. .
And the machine next to the single platform is not eye-catching. For Wu Yili, it is another innovation on the road to pancakes.
This is a machine loaded with a 3D printing system, or it is called a "smart pancake printer."
Cross-border cooperation between classmates
The idea of ​​printing pancakes began with a class reunion during the Spring Festival this year. At that time, Wu Yili gave a half-joking joking to the classmate of the same year. Can you print pancakes with a 3D printer?
"Everyone thinks that it is very fun, why not try it?" Like Wu Yili, Shi Yule is also an entrepreneur, and the direction of entrepreneurship is "3D printing." The “soft sea core†he founded is an uncompromising high-tech company providing 3D printing software, equipment and services.
"What we always wanted to do is to pull 3D printing down the altar." Shi Xiaole told the Science Daily reporter that people may have heard about 3D printing more or less, but few people have actually seen 3D printers, not to mention direct Operate this machine. And they hope that everyone can be a 3D print designer.
Wu Yili’s proposal puts a bridge between “food†and “technologyâ€. The two companies that seem to be out of bounds have launched this wonderful cooperation.
In the summer of this year, “Easy Good Fortune†and “Qingsoft Haixin†jointly established “Xiaofeixia†Technology Co., Ltd. Peter Pan, a fairy tale in a fairy tale, is a little boy who will never grow up.
"Our people, using 3D printers to print pancakes, are actually like little children." Wu Yili said that they insist on using "love" and "awe-inspiring heart" to make food; they also want to use high technology to create happiness.
Print pancakes, it sounds low, it's not easy to do
“At the beginning, we seriously underestimated the difficulty of making pancake printers.†Shi Yule said that the first problem they encountered was the distortion of the printing effect caused by the stickiness of the colloidal liquid.
The nozzle of the dough is too close to the baking sheet. It takes a long time to paste. It is far from the baking sheet. The shape of the “battering†is difficult to control. I wanted to let it go straight, but the fluid will spin when it falls. The printed trajectory does not exactly match the trajectory of the printhead (ie, the nozzle of the cartridge). At this time, it is necessary to use fluid mechanics to study the law of falling and forming of the slurry, and then use the computer to carry out the inverse calculation, and then repeatedly adjust to achieve the best effect of pattern forming.
The pattern can be played, but the machine is too loud and affects the user experience. The print head should be "walking" with a barrel containing nearly a pound of dough, and the weight is also large. At the beginning, once working, the whole machine "sounds everywhere." The team will check the machine's resonance point a little bit, adjust the "printing head" moving speed and turning angle to make the pancake printer quiet.
These are all within the scope of the Shihler team's experience in 3D printers. However, they are going to print "food" this time, and even the heat transfer method of the baking tray has to be considered.
“The pancakes that were first made out were very good; but we turned the pancakes over and saw that some places were already pasted and some were not cooked.†So they modified the bottom structure of the baking tray and heated it. Heat conduction is changed to "thermal radiation" to achieve uniform heating.
"In short, there are too many details that need to be modified and not thought of before." Shi Yule recalled that they had made one or two hundred changes in size; nowadays, the pancake printer that will really come out is already iterative four or five times. After the product.
Wu Yili revealed that the official name of the printer is “Three Brothers Painting Cakeâ€: “Hardware modeling, software performance and ease of use will all be a step higher than the current one.†The printer in Wu Yili’s store is the second generation. A "good luck" employee who has never operated a printer is also quick to get started: loading the barrel, selecting the pattern on the tablet, and printing a "Little Yellow Man" pancake for the reporter - printing takes 2 Minutes or so.
In the face of doubts, I asked aloud, "Is this still not innovative?"
Is Peter Pan a company that sells pancake printers?
Yes, but not all.
"We want to turn pancakes into media." Wu Yili said.
Before the end of this year, the “Three Brothers Painting Cake†pancake printer will be mass-produced and sold simultaneously at home and abroad. When customers scan their WeChat public account, they can freely upload their own creative “pancakes†with various designs; the system will distribute the order to the nearest pancake printer from the customer's location; after printing, the customer You can pick it up yourself or you can choose to deliver it to the delivery staff. Even if the two separate the two places, you can use this way to "transfer" through the pancakes, or even "truth".
At this point, the customer really became a "3D print designer"; and, this identity change has almost no threshold.
Wu Yili counted, using traditional methods to spread pancakes. One person can spread up to three cakes at the same time; but with a pancake printer, one employee can take care of 20 machines at the same time. “This is a real innovation, the liberation of the workforce, is it not innovative?â€
In fact, both Wu Yili and Shi Yule know that what they are doing, besides being concerned, has also been questioned: Tsinghua graduates of computer software professionally go to pancakes? waste! Use a tall 3D printer to print pancakes? waste!
“What do you mean by making a screw in an already mature commercial system? At least now I am doing my own brand, I am improving the service level of the small stalls, I am using automation to save labor, these are Real innovation and change.†Wu Yili said that it is more interesting to do “making pancakesâ€, that is, “meaningâ€.
For Shi Lang, he is also practicing his initial heart-starting business – letting 3D printing penetrate into people's daily lives. "3D printers are still only tools for professionals, not ordinary people's toys." When I was at school, the teacher taught me that software could not be "self-defeating", and the software service should be targeted at thousands of households; Shi Xile, convinced that good technology should "fly into the homes of ordinary people." Pancake printers may be one of the examples of commercialized “grounded gas†applications for 3D printing.
“Thousands of people can make money with our stuff. Isn't this the value that Tsinghua graduates should pursue? Some people say that printing pancakes is a bit low, but we are very focused and happy.†It is said that 3D printing may enter your life quietly in a way that is “smooth and silentâ€, and then “thousand trees and pears bloomâ€.
On October 8th, the “Three Brothers Painting Cake†pancake printer will be crowdfunded in Jingdong. Not surprisingly, this would be the first pancake printer in the world to be mass-produced.
