A Home 3D Printer

From November 25 to 27, the 2022 World Internet of Things Expo was held in Wuxi. In the interior exhibition area of the Internet of Things application for product exhibition in the Taihu International Expo Center in Wuxi, a batch of new technologies and applications of the Internet of Things are dazzling. After experiencing them, visitors have a feeling of "suddenly enlightened": it turns out that the Internet of Things and the digital technology and digital economy based on it have so deeply affected our lives.

3D printing goes into the toys that ordinary people like to play by themselves

"How much is this' tank '? How much is this (3D) printer? Can you print by yourself?" 3D printing technology and its application based on digital technology have won many fans on the site of the Expo.

In front of a 3D printed "toy tank" model, a mother who took her children to visit asked the staff about the "price". Because there were many 3D printed toys on display, the children couldn't put it down. After reading this, she wanted to play with that, and she wanted to buy a printer. At the scene, in addition to the tanks that boys like, there are also dolls that little girls like. They are different in variety, shape and complexity.

The staff of Mingya Technology, who participated in the exhibition, said that they are an enterprise engaged in industrial 3D printing services, providing 3D printing services in the fields of digital medicine, automobile research and development, aerospace, industrial parts, architectural design and artistic creativity. That is, from industrial equipment such as machine tools to small toys on the desktop, they can all be achieved through 3D printing. At the same time, 3D printers with prices ranging from a few hundred yuan to tens of millions of yuan were also introduced. "You can just buy a few hundred yuan for fun, because you don't need such a large size and complicated things!"

"What about this industrial part? Can it be mass produced?" An industry person concerned about the application of this 3D printer in practical work. The staff replied that it is mainly to do a small amount of "samples", which is also an original intention of 3D printing technology. However, compared with a few years ago, the quality and efficiency of printing have improved a lot.

More than 10000 people take unmanned "microbus"

The Internet of Things is changing travel

"I have been driving for 10 months. I have taken about ten thousand passengers, and the acceptance of citizens is getting higher and higher." The "Internet of Vehicles Town" in Wuxi Xidong New City has opened the "Xidong minibus" which is driverless. It has become a popular carrier for many people to experience driverless driving and the Internet of Things, which is also one of the top ten Internet of Things application scenarios created in Wuxi.

The staff of Aerospace Dawei Science and Technology told the reporter that there are six "Xidong minibuses". The route is fixed and there are three available for citizens to choose. They mainly run between residential areas and subway stations. The daily operation starts at 7 o'clock and ends at 9 o'clock. It is also easy to take the bus. Make an appointment through the small program "Xidong minibus" in advance, then choose the route to take, and then go to the platform according to the appointment time. After scanning the code, you can travel. "Although it is driverless, there is a security guard on the bus, and thousands of people take it every day."

The staff said that the automatic operation of this unmanned minibus is inseparable from millimeter wave radar, positioning system, etc. There is a special calculation unit on the vehicle, which collects information and integrates the running tracks of pedestrians and vehicles around the vehicle to independently judge deceleration and avoidance. It can also interact with the intersection equipment to receive information such as whether there are vehicles at the turning and whether there are pedestrians at the intersection of the community, so as to make a passing judgment.

Driverless delivery vehicle

Take out to college dormitories

"This delivery truck, which is currently used in schools, has been running for more than a year and is in good condition." The staff of Youdi Science and Technology, who participated in the exhibition, told the reporter that college students now like to order takeout. In response to this need, some college canteen departments have purchased such driverless delivery vehicles to deliver the meals packaged in the canteen directly, which can be delivered to the students' dormitories downstairs. It is also very convenient for students to use. As long as you move your fingers and place an order, you can quickly receive the takeout from the school canteen.

In addition, the participating enterprise also displayed robots that are suitable for entertainment and catering places. Through digital technology, the robot can achieve full autonomous navigation, plan the optimal path, and send it to specific areas of KTV, cinemas, cultural cafes and other places, which is welcomed by customers. Most of the equipment is tall and inconspicuous, but it is quite intelligent. Obstacle avoidance is not a problem. "These machines are both expensive and cheap. The overall choice and demand are very good. Many customers' experience feedback is good."

The size of online shopping clothes is always wrong?

This method can solve the problem

Xiao Qiu, a tall and fat college student, usually buys clothes online. Although customer service outlets also tell him that they can recommend clothes of appropriate size as long as they provide some basic information, such as height, weight and waist circumference, they are often not very suitable.

When visiting the World Expo, he decided to try the 3D measurement system displayed by Red Bean Menswear to see if this "so-called" intelligent device can really quickly push him the right clothes? On the spot, he stood at the center of the equipment, and then the surrounding instruments began to run up and down scanning data. In just 30 seconds, his detailed "dressing" data appeared, which surprised him. "I think if clothing stores have these, or if they can do so online, I won't have to be so bored when buying clothes."

The staff said that this system is a combination of advanced AI intelligent volume technology and industrial manufacturing technology. For clothing customization, it can achieve real personalization. At present, this system has been used in many stores of the brand.
