Unbelievable but true: driving across America with a single tank of fuel. This new breakthrough also takes place with the help of 3D printers. Is the era of abundance predicted by Cornucopians like Ray Kurzweil finally coming?
At low speeds, a car's fuel consumption is proportional to its weight. But how do you get the weight down without compromising on safety? The answer: with a 3D printer. The URBEE 2 will be able to drive across America with a full 45 liter tank. 3D printing giant Stratasys supplied the printer, KOR EcoLogic, in collaboration with Stratasys subsidiary RedEye On Demand, supplied the design and technical implementation. The chassis of cars usually consists of hundreds of parts. The chassis of this design contains only 40 separate parts, all of which can be printed from ABS, a thermoplastic plastic material. However, the motor, battery and the like must be obtained from other sources. The small number of loose parts makes the implementation almost seamless, resulting in an extremely low drag coefficient: 0.15, which greatly reduces air resistance. In comparison: a moving cube scores 1, a sphere 0.5.
Although the weight is only half that of a conventional car, the impact protection is the same due to the strength of the material from which the car is printed. The low weight also leads to extremely low fuel consumption. The builders plan a drive from Los Angeles, on the South Pacific, to New York City on the East Coast, on a full tank of about 45 liters of gasoline. This equates to a distance of 4500 km and therefore a fuel consumption of 1: 100. The test will be carried out with bioethanol, which is not very environmentally friendly.
With this trial, Stratasys wants to demonstrate that large runs of high-quality products can also be produced with 3D printers. Obviously with the intention of being able to sell many 3D printers to manufacturers all over the world. The era of great abundance is getting closer.
