Recently, the appearance of a 3D-printed car named Strati, which was printed and assembled by Local Motors, Cincinnati Inc. and Oak Ridge National Laboratory, has caused great concern. So, such a problem has emerged, 3D printing can change the traditional manufacturing industry? In the future, can 3D printing cars really run on the road?
For this reason, experts from the Institute of Automotive Research, who are unwilling to be named, believe that “the problem of materials is the key. Is there any material with such high strength that can print out the car? The materials used in the car are required to meet the safety standards, and the materials used in 3D printing are plainly Is plastic, print model is no problem, print out the actual car is running on the road is a problem ".
However, car owners expressed different views. “3D printing of cars is one direction afterwards. We currently have a lot of parts when we do pre-fast prototyping. We have already adopted 3D printing technology and will be used by OEMs. It is difficult for all vehicles to use 3D printing, and it is unlikely. It is still very likely that parts will be printed in 3D, "said Dongfeng Group's internal technical personnel in an interview with the "Securities Daily" reporter.
Short-term dreams can hardly come into reality
According to media reports, the 3D-printed car named Strati uses Bridgestone Battlax tires, and its theoretical maximum speed is 50 miles per hour. For safety reasons, the early model of this car will be limited in speed, with a maximum speed of no more than 25 mph. Due to the lack of speed, this car saves some safety equipment such as seatbelts and airbags.
In addition to components such as motors, batteries, wires, seats, windshields, suspensions, wheels, etc., nearly 50 parts that cannot be moved, are not cleaned, and are not electrically conductive are all manufactured using 3D printing technology. It is reported that LocalMotors plans to get the car to get a legal permission to go on the road, and it will begin sales next year, priced at about 18,000 US dollars.
It can be said that the days of 3D printing cars from the dream into reality are not far! However, even if there have been 3D printing cars that can run on the road, the above experts still think this is not realistic. "3D technology was applied long ago and was first used in car models. This is not something new. I believe that 3D can print out a car, but it has no practical significance. 3D printing cars is more of a concept. Not in line with reality. "
In his opinion, the advantages of 3D printing are relatively simple and cost-effective. However, there is no way to print complex structures. The appearance is no problem, and there are problems with the durability and precision of the material.
It is unlikely that the vehicle will achieve 3D printing
"3D printing is fast and very efficient. If its performance, durability, and maturity are higher in the future, more and more 3D printing will be used," said the car maker.
He stressed that the use of 3D printing for all vehicles is difficult and unlikely, and that some parts using 3D printing are still very likely. Because there are some parts and components that are still very complicated, especially electronic parts, it is unlikely that 3D printing will be used for parts related to electricity.
Needless to say, it is absolutely impossible to say that 3D printing cars can change the traditional car manufacturing industry. Indeed, it sounds like a 3D printing car is a very fashionable concept, but the car is still a product with very high requirements for safety performance, so that 3D printing cars really run up the road, and the actual conditions are not really available.
It can be said that in the future, some parts that do not have high performance requirements can use 3D printing technology. In the future, 3D printing may also be applied to some parts with complex technical requirements. However, some large parts such as engines, gearboxes or difficult to achieve 3D printing.
At the same time, the above-mentioned experts believe that the material issue is not a problem for the above-mentioned auto makers. "It's nothing more than a difference between printing or making a mold. The cost of early molds is expensive, 3D printing is cheap, and you can quickly print out what you want."
According to him, at present, there are almost no 3D printed parts and components sold on the market. Only in the development process, the early experimental stage, the traditional mode is the use of molds, which can now be printed out using 3D technology.
