However, 3D printing technology has never been easy to try for cars with higher overall strength requirements. Now, with the blessing of new composite materials, 3D printing cars are on the road. Recently, according to foreign media reports, the British 3D printing company scaled Ltd has released an electric four-wheel 3D printing car called chameleon, which can reach 45 miles per hour (about 70 km / h). It is said that the chameleon is the first 3D printing car in Europe. < p > < p > it is reported that the chameleon project was initiated by scaled company, headquartered in Sweden, during the period of the epidemic blockade order. In the process of building, we use the software tool chain, manufacturing process, supply chain, 3D printing system and other synonymous production platforms. Bob Bradley, co-founder and technical director of scaled, explained that at the beginning of the project, there was not even a suitable 3D printing machine on the market. < / P > < p > the printing plastic chassis of the vehicle is optimized by rafinex’s random software. Lehvoss group also provides PA6 3D printing material, which ensures that the vehicle can bear enough load during driving. < / P > < p > due to the technical characteristics of 3D printing, this “chameleon” looks more like a semi-finished beach car with only one driver’s seat and no comfort configuration. However, it also proves the feasibility of 3D printing technology for printing cars. < / P > < p > it is reported that the chameleon electric vehicle is equipped with a Lynch electric engine and weighs 150 kg. Powered by power batteries, the car can reach a top speed of 45 mph. < / P > < p > and scaled was founded at the end of 2015 to provide large-scale 3D printing products to the UK market. At the beginning of its establishment, the company has established three large production lines, one of which can print materials up to 3 meters in length. Didi Qingju bicycle has entered 150 cities
