Although the 3D printing technology has successfully simplified the traditional and complex production processes and programmed the difficult problems in the materials field, there are still some problems in how to expand the application of the 3D printing technology. It is also constrained and influenced by technical equipment, new materials, design software, quality safety and the public environment.

In addition, 3D printing cannot completely replace traditional CNC machining. Both of these have their own advantages. CNC machining accuracy is higher than 3D printing, and the complexity of 3D printing-manufactured parts is much higher than that of CNC. 3D printing is an important supplement to traditional processing methods. Its main function is not to replace but to supplement. Therefore, 3D printing and CNC integration are a very good form.

In the future, only by combining the personalization, complexity, and difficulty of 3D printing technology with the scale, mass, and refinement of traditional manufacturing, combined with manufacturing technology, information technology, and material technology can we continue to promote 3D. Printing Technology Innovation Development in the Automotive Industry.

In 2014, Local Motors launched an upgraded version of the Stratati 3D printer. The car’s first step was that its chassis was also made using 3D printing technology. Second, its printing time was only 44. Hours. If you add assembly time, the latest data shows that it takes only three days to build Strati. From 100 days to 3 days, the rapid increase in efficiency indicates that the future development of 3D printing cars cannot be predicted.

EDAG, a German independent car design company, brought a 3D printing concept car LightCocoon at the 2015 Geneva Motor Show. The new car shell weighs only 19 grams per square meter and is a quarter of A4 paper. Although 3D printers are constantly evolving and upgrading, objectively speaking, the application of 3D printing technology in the automotive field is not yet its strength, because the automobile is a mass-produced product, and 3D printing is currently more suitable for personalized products and Production of small batches of products.

Experts said that currently there are five main applications:

1, for the design;

2. Direct production of structurally complex parts;

3. Production of lightweight structural parts on automobiles;

4, custom special parts and testing equipment;

5, the production of vehicle models.

However, it is worth mentioning that the practical significance of 3D printing equipment is to help you improve the efficiency of a certain part of the process of design or product sample preparation, rather than completely replace the entire process. Just like Urbee, 3D printers can print body shells, body weights, and personalized designs for them, but the key components such as motors still come from traditional manufacturing. The biggest difference from a traditional enterprise manufacturing car is that 3D printing cars print a single, one-piece car body and then fill in other parts instead of assembling parts of the car body together.
