Research On Application Of3D Printing Technology In Automobile Manufacturing And Maintenance

In recent rapid increase in car ownership in China, the domestic autocompanies to increase year by year, foreign car companies are alsodeveloping the Chinese market as a top priority, auto companiesincreasingly fierce competition. With the rise in ownership ofautomobile exhaust has become the largest source of air pollution, haze,represented in harsh air conditions seriously affect people’s normalproduction and life. In this case the auto companies need to considerhow we can improve vehicle production efficiency, reduce costs andproduce higher automobile fuel efficiency, more personalized appearancemore attractive to consumers.3D printing technology and the emergenceof3D printing the first car to the traditional automobile productionhas brought new reference,3D printing technology with a simpleproduction process without molds and other relatively low-cost,high-efficiency quick access to people sight, car companies began toconsider how to take full advantage of its features to its full advantage,making the automotive business lead to higher productivity and greaterprofit margins. From " Made in China" to transition " Chinese wisdommade" need to rely on intelligence and digital implementation. How tomake a real3D printing technology to the Chinese automobile productionand maintenance companies to become the best interests of the purposeand focus of this study.This paper first describes the3D printing technology is currentlyapplied in the international status of the country, forming principleintroduced several common3D printing technology and process design andprint wheel hub example detailing the working principle of3D printingtechnology and the technology needs supporting STL file format andassistive technology (3D digital design), based on the advantages anddisadvantages of3D printing technology analyzes the advantages of automotive manufacturing and automotive repair field of3D printingtechnology has the following four points, respectively, to acceleratedevelopment speed,3D printing lower fuel consumption and moreenvironmentally friendly vehicles, reduce costs, can be customizedaccording to customer demand. There are technical limitations of theapplication is not mature enough cause print speed is not high, the highcost of equipment and raw materials, production quality is notguaranteed yield instability and other issues, come the next shortperiod of3D printing technology can not completely replace thetraditional production line, but should with the traditional way withthe use of industrial manufacturing, making the car a substantialincrease in production efficiency, product replacement rate furtheraccelerated. From the producer point of view to study the3D printingtechnology in the field of automobile production.High-end cars, imported cars repair the problem has been quite difficultto repair your highlights, imported cars car ownership in China is less,the same amount less maintenance and replacement parts, repairs mustbe re-ordered if there are even imported from abroad, cumbersome, longcycle inevitable, and the purchase price of a single channel is boundto make parts too.3D printing technology can use the digital modelsand technical data needed to print out parts directly when there ismaintenance, eliminating a lot of trouble can also reduce costs. Vehiclemaintenance areas not currently use3D printing technology,3D printers,and the main reason there are currently still relatively high rawmaterial costs, the printed part quality and no testing standards,intellectual property rights auto parts automotive repair professionalsthere is the level of knowledge not higher4, there is the issue ofintellectual property rights is mainly not a good solution, when thisissue is resolved the3D printing technology can quickly print a smallamount, the advantages of complex custom items can be fully reflected,this advantage is ideal for car repair business Some require a small amount of fast access to special parts or repair tool features. So longas these problems are solved several3D printing technology in theautomotive repair industry also has a good prospect.In summary,3D printing technology is well suited to its unique advantagein the automotive industry, including automotive production and serviceindustries.
