2 people, 4676 kilometers, 37.85 liters of fuel, driving a 3D printed car Urbee 2 from New York to San Francisco, this is the plan of Jim Kor team. They want to prove to the public the importance of saving fossil fuels through this deed through the United States. The departure time is scheduled for the summer of 2015, and the entire trip is expected to take 2 days, with an average speed of 111 kilometers per hour. Of course, the premise of this is that Jim Kor can raise enough funds on Kickstarter-$ 30,000.
Readers about the Urbee car are not unfamiliar. It is the world ’s first car produced using 3D printing technology. Of course, URbee itself is assembled by hand. Here it is said that its body cover and other materials are made with a 3D printer. This time through the US plan to use the second generation model, namely Urbee 2. According to Kim Kor, Urbee 2 not only produces the body shell by a 3D printer, but also produces the interior by a 3D printer.
Urbee's early 6: 1 model was born in 2010, and the first prototype was released in early 2013. The first generation of Urbee's body covering was made with a 3D printer, using ABS plastic. Although the concept of 3D printing is extremely popular this year, Urbee was not born to promote the development of the 3D printing industry. The reason why 3D printing was used was that when the fiberglass material was first selected for the car body, the production cost and production time were limited.
Finally, Jim Kor found Stratasys, a provider of 3D printing solutions. Using the company's FDM technology, Urbee's team was able to produce a body part in a few days. For Urbee, which does not have a production line to support pure hand-made, it takes a few months to complete the production if the traditional production method is sought. From the clay model on the original workbench to the birth of a 1: 1 real car, Jim Kor finally found the solution: print a car.
Urbee's shape is very peculiar, it only has 3 wheels. This flat shape makes the wind resistance coefficient reach 0.15, which is a very good number in the design of the automotive industry, so that it can avoid air resistance to the greatest extent. The tricycle design is also based on this consideration. In terms of power, Urbee uses a hybrid power system, two electric motors plus an engine, and the engine uses ethanol fuel. The battery can be charged through the solar panel on top of Urbee. In short everything is to save fuel consumption to the greatest extent.
While marveling at the magic of 3D printing, I also began to question how practical this car is. It is undeniable that 3D printing technology is a subversion of the manufacturing process, but is the strength of the body structure made with 3D printers enough? Safe How about sex? If there is an impact accident on the road, will it fall apart? More importantly, Urbee 2 has to cross the United States for 42 hours of uninterrupted travel. It has to deal with various climates and road conditions. Are you confident about the endurance performance of the car? Driving Urbee 2 will be Jim Kor's two children, Tyler and Cody, and a dog. One can't help but question whether the crossing plan will end in farce.
I do n’t deny that Urbee is a crazy invention by Jim Kor, a group of makers, and they are a beneficial contribution to the environment and car design. But it finally fell to the practicality of the car's most substantial problem. Urbee 2 looks like a big toy. Jim Kor has nearly 40 years of engineering background and has been involved in the design of urban buses, cars, aviation and even commercial swimming pools. I believe that he can grasp the design of the automobile industry and can run from New York to San Francisco with 38 liters of fuel in 42 hours at an average speed of 111 kilometers per hour. This is not a joke.
In 1903, Horatio Jackson and his mechanic Sewall K. Crocker drove a Winton car from San Francisco to New York, which took 2 months and 9 days and consumed 3000 liters of gasoline. Jim Kor apparently wanted to stage such an initiative again to make an out-and-out reality show advertisement for the commercialization of the car in a2015. Currently, Urbee 2 has raised more than $ 2,000 on Kickstarter, and its goal is $ 30,000.
