FDM-3D printing technology application and automotive industry

The FDM principle is based on fused deposition modeling, and the material is usually made of plastic into filaments, called fused filaments. During the printing process, the FDM printer heats the fused filament to a molten state and then extrudes it onto the printing platform through the extrusion head. The extrusion head stacks the molten filaments layer by layer at a certain speed and temperature according to the path and shape indicated by the code, ultimately forming a three-dimensional object.

FDM 3D printing technology is currently the most widely used 3D printing technology. In the automotive design stage, 3D printing can quickly produce concept models and functional prototypes, which can greatly improve the product development process in the early stages of product development.
Greatly shorten the verification time of automobile parts, thereby shortening the automobile development cycle and minimizing the cost waste caused by design reasons.

Functional test prototype
Currently, commonly used FDM reinforcement materials include carbon fiber and glass fiber, which can be used to reinforce ABS, nylon (PA), polypropylene (PP), polyetheretherketone (PEEK), and other materials. Therefore, printing this kind of high performance requires the use of high-configuration industrial-grade FDM printers.

Automotive equipment components
Manufacturing is constantly adapting to meet new demands. Demands such as customization, on-demand production, and small batch production are constantly creating alternatives to traditional manufacturing methods. Additive manufacturing technology may never completely replace CNC machine tool processing or casting, but industrial-grade high-performance FDM printers can meet these batch manufacturing requirements.
Carbon fiber-filled nylon materials have higher performance than pure nylon (reinforced carbon fiber nylon). Taking Nyon12-CF as an example, it is obtained by blending chopped carbon fibers with nylon 12.
The 35% reinforced fiber content composite has excellent structural properties and is one of the strongest thermoplastics in the FDM material portfolio.

Work fixture
For the trial production stage of new models, a large number of new tooling fixtures are often put into use, and they need to be continuously optimized and adjusted. 3D printing greatly saves the cost of tooling fixtures in the early trial production stage.
Production time can save a lot of costs. PC has high strength and flexural strength properties, which makes it an ideal tool, fixture, and pattern for demanding molding needs, metal bending, and composite work.
Ideal for your case. Small batch production and customization become feasible, and testing becomes more reliable. General Motors has used 3D printing for product development for more than thirty years and in the past decade, more than 250,000 parts were produced using 3D printing technology.

Automobile after-sales maintenance field
3D printing has fewer applications in the automotive maintenance industry, but it has huge potential. 3D printing equipment and materials, automobile property rights protection, post-printing quality inspection, and skills of automobile maintenance practitioners
Level and understanding of technology are important reasons that limit the application of this technology in the automobile maintenance industry. This requires automobile maintenance companies to have the ability to customize parts and components, and 3D printing technology can provide important guarantees for the repair of missing parts for various models. From car repair tools to direct manufacturing of parts, 3D printing can undoubtedly play an important role. The most direct manifestation is that it can save maintenance waiting time and solve the problem of waiting and hiring.
Cost issues caused by original factory professionals.
