Is Shanghai Wisdom Bay Science Park in Baoshan? 3D？ The holy land of printing, here? 3D？ Strong culture, not only in China? 3D？ Printmaking museum, there is another one in the park? 3D？ Printed concrete bridge, fans will punch in every time they come here.
In this area? 3D？ There is a startup company with a strong printing atmosphere in the park, covering an area of 1000 square meters, with bright windows and simple decoration. What is the name of this room? XEV？ What does the company do? 3D？ Printing was born, and the printed objects were quite interesting, not others, but electric cars.
XEV？ Founder Devin Lu is famous in the field of automobile design. Devin Lu works for the largest design company in the world? ARUP？ As the head of automobile business in China, 26? /kloc-At the age of 0/8, Devin Lu, who was brilliant, took on a great responsibility. At that time, JAC asked him to set up a design center in Italy and become the senior director of JAC global design. Since then, he has settled in Europe and made great contributions to Jianghuai navigation.
Like many famous entrepreneurs, Devin Lu, who has lived in a big factory for many years, finally decided to start a business in the sea and enter a new stage of his career. Boldly speaking, Devin Lu, who started his business for the first time, chose a relatively unfamiliar field-3D? Print cars.
In the ascendant? 3D？ print
Actually, 3D? Printing technology is not new. 1986? 1998, American Charles Hull formally applied for the patent of three-dimensional curing technology, which has been developed for more than 30 years.
Hull found in his work that liquid resin will solidify when it meets ultraviolet rays. He thought that if ultraviolet rays can be swept on the surface of photopolymer layer by layer, it will become solid layer by layer, and these hundreds of thin layers will be superimposed together, so any three-dimensional object can be made.
Simply put, 3D? The technical logic of printing is to stack materials layer by layer to form two cores of this technology. Which one? 3D？ Printing equipment and consumables. And according to the differences in printing accuracy, speed and size, 3D? Printing is divided into desktop level and industrial level, industrial level 3D? Printing is relatively more demanding.
Used in auto parts? 3D？ It is industrial-grade, with high requirements on accuracy, speed and component volume. As a vehicle component, regular? 3D？ Printing materials such as nylon glass fiber, durable nylon material, gypsum material and rubber are difficult to meet the strength requirements of vehicles, and a considerable part of the materials of a vehicle still rely on metal materials such as aluminum and high-strength steel.
Then the problem is coming. This kind of materials tend to have slow printing speed and relatively high cost. At present, dozens of metals such as titanium alloy and high strength steel have been developed in China, but the properties of molded products are generally not high. This is also industrial grade? 3D？ Printing, especially cars? 3D？ Bottleneck of printing technology development.
Is it currently used in the automotive field? 3D？ The best printing technology is BMW. i8？ Roadster？ Metal convertible soft top bracket, window guide rail, MINI? Customized accessories, etc. , all by? 3D？ Printing, but it is difficult to form scale effect, and the cost is still high. All this time, auto parts? 3D？ Printing has never been able to scale up, and only exists in the production of a few complex parts.
Or, 3D? The prospect of printing cars is still considerable, and the market is still a blue ocean.
According to Devin Lu, traditional automobile manufacturing has gone through complicated processes such as mold opening, design and manufacturing, with long research and development cycle and high time cost. Traditional manufacturing often needs? 36? Next month, how much will it cost? 5? A billion, and then what? 3D？ Printing only needs? 12? Next month, the cost is not much? 3000? Wan.
In contrast, there is no need for mold opening and stamping welding? 3D？ Printing cars is very cheap. But because of the high technical difficulty, take root in cars? 3D？ Few players printed, which made Rudy see the opportunity.
XEV？ Where is the confidence?
Facing the car? 3D？ Devin Lu is full of confidence in the plight of printing.
The first is the improvement of efficiency. What did Devin Lu introduce to us? XEV？ The following technical highlights:
They specialize in equipment optimization for the automobile industry, which is more common than the market? 3D？ Is the printer efficient? 4? Times;
Can the second generation machine print? 1000? × 1000× 1000mm？ And then what? 2000× 1000× 1000mm？ Large-size parts of;
What is the maximum printing speed? 300 mm/s;
Can it be realized? 0.05mm？ Motion accuracy of;
Is the temperature of the print head close? At 350℃, how much can the printing heat preservation warehouse reach? 60℃;
High performance control panel, which can process multi-directional data at the same time.
With the help of manipulator post-processing equipment with excellent performance and algorithm, XEV? Have leading post-processing technology. The robot can perform various operations to select the appropriate tool changer (EE), such as recognizing the position of the workpiece, milling, grinding and so on.
After the computer generates the tool path, the human operator only needs to assemble, select the program and disassemble, and the tool path will automatically adapt to the actual position of the workpiece, the end effector will automatically work, and the robot will automatically replace the sandpaper to replace the end effector, completing a series of automatic operations in a cycle.
How many industrial grades are there? 3D？ Printer, XEV? Built a mini electric car with its own brand? Yo-yo.
Has this car been measured? 250? x？ 150? x？ 147cm, battery life? 150- 180? Kilometers, top speed? 70km/h, the structure is relatively simple. According to Devin Lu, yo-yo? what's up 3D？ The mass production of printed matter is divided into two stages.
The first is the printing of some simple interior and exterior decorative accessories, such as exterior doors, side body decorative panels, front bumper inlays, speaker covers and so on. Then the front and rear fenders, doorsill, spoiler, instrument panel and other parts are printed and mass-produced, and finally the whole vehicle is realized? 60%? what's up 3D？ Print.
Devin Lu said frankly, XEV? At present, our body frame, body steel plate and chassis parts are all made of. These components have low production cost and modular design is easy to assemble.
Double income of vehicle and technical solutions
Having lived in Europe for many years, Devin Lu is well aware of Europeans' obsession with mini-cars. YOYO？ One car took the lead in entering the European market and was recognized by the European market once it was listed. Compared with competitive products, the pricing of euro is very attractive. Devin Lu said that they have received information from the Italian local authorities? 5000? An order for a car is quite good for a startup.
While harvesting vehicle orders, Devin Lu also exported equipment technology to car companies. Expected? 202 1? Year, XEV? Will it be delivered externally? 30? Taiwan Province? 3D？ Printer, and provide supporting solutions.
After the success of the first European War, YOYO? Will further explore the domestic market, Devin Lu asked me with a smile: "The price of this car in China is less than 40,000 yuan. Do you find it attractive? "
I'm not sure, okay? YOYO？ Can it sell well, but I'm sure that the mini-car market in China is far from saturated. First, it is convenient and economical for micro-electric vehicles to commute in first-tier cities; In addition, the third-and fourth-tier cities have limited area and convenient charging, which is very suitable for micro-electric vehicle scenes.
The reason why micro-electric vehicles are frustrated in China is largely due to the flood of fake and inferior products in the market, which makes its image deeply bound up with "Old People's Music". China people don't need cars, what they need is exquisite cars, especially the young people who are pursuing quality at present.
Taste it? YOYO？ After this car, I think it is still very competitive.
