Oavsett alla andra synpunkter man kan ha på bilen så är det intressant att man försöker ta 3D-skrivarna in i massproduktion av bilar.

The electric car comes from the 3D printer
XEV's first 3D-printing electric vehicle will be launched in spring 2019. The so-called Low Speed Electric Vehicle celebrates its premiere in a 3D museum a month before the Beijing Motor Show. The developers are convinced of the 3D technology.
Already 7,000 pre-orders for the 3D printing car

The Italian-based Star-Up X Electrical Vehicle (XEV) will present its 3D-printed LSEV at the 3D Printing Cultural Museum in Shanghai, one month ahead of the Beijing Motor Show (24 April - 4 May 2018). At the end of this year, series production will start. The prototype of the LSEV was developed in collaboration with the Shanghai 3D specialist Polymaker, who was responsible for the research and development of the printed material. "The research and development process of a car model usually takes between three and five years, but 3D-printed cars such as the LSEV only need between three months and twelve months," said Luo Xiaofan, founder and CEO of Polymaker.
Guo Xiaozheng, senior designer of XEV, was also pleased: "We have already received 7,000 pre-orders, including from the Italian post office and car rental company Arval, and many Chinese companies have also shown interest in our product." It will continue to improve the model according to customer feedback and offer "tailored features," added Guo. "Unlike other 3D printed cars, the LSEV can be mass produced." However, the idea of an electric car from the 3D printer is not entirely new: in the autumn of 2017, for example, the Austrian Roman Haslauer introduced the small car "enjoy" - this vehicle was also built using 3D technology.
Less components, less costs
Using 3D printing technology has reduced the number of plastic parts and components from more than 2,000 to 57, while reducing research and development time by two-thirds, said Zhu Li, director of the 3D Printing Cultural Museum in Shanghai. Apart from the chassis, seats and glass, all visible parts of the car are manufactured using 3D printing technology, reducing investment costs by more than 70 percent compared to a traditional vehicle, Guo continued.
The reduced overall weight is also expected to have a positive effect on energy consumption and thus on the life cycle assessment: the LSEV weighs about 450 kilograms - without a battery - and thus significantly less than cars made from conventional materials. Whether the savings in material and development time also reflected in the retail price, remains to be seen: What the 3D electric car should cost, the project partners have not yet revealed. (AHO)
