Application Case | End-to-End Solution for 3D Printing Automotive Parts

In the wave of Industry 4.0, 3D printing technology is revolutionizing the manufacturing industry with its unparalleled advantages. As an essential part of the industry, automotive manufacturing is also actively exploring the applications of 3D printing in rapid prototyping, component production, and personalized customization.

Today, we will delve into how KEXCELLED collaborates with partners INTAMSYS and Sika to provide cutting-edge 3D printing solutions for the automotive industry.

3D Printing and Automobile Manufacturing

The automotive manufacturing industry has always been a crucial domain for technological innovation, and 3D printing, as an emerging manufacturing technology, has infused new vitality into the automotive manufacturing sector. Especially in the following three aspects, 3D printing technology demonstrates significant advantages:

· Accelerate Prototype Development: By using 3D printing technology, automotive designers can quickly turn concept sketches into physical prototypes, significantly reducing the development cycle and enhancing the efficiency of design iterations and testing.

· Produce Lightweight Components: The precision and flexibility of 3D printing enable the production of structurally complex yet lightweight components, achieving automotive lightweighting and thereby enhancing fuel efficiency and dynamic performance of vehicles.

· Customization and Short-Batch Production: 3D printing supports highly customized and short-batch production, allowing manufacturers to produce components based on specific customer demands or special applications, breaking through the limitations of traditional manufacturing methods.

3D Printing Equipment: INTAMSYS FUNMAT PRO 410, an industrial-grade dual-nozzle high-temperature 3D printing device, features a printing size of 305305406mm, wire filament sealed drying technology, and the capability to cover multiple materials. This equipment can print PA engineering plastics with exceptional precision and quality, creating intricate and high-quality printed components, accurately replicating the design models of automotive parts.

Finished 3D Printed Automotive Components

3D Printing Material: KEXCELLED PAHT K7 filament, a high-rigidity, high-performance, and user-friendly polyamide material based on PA6. The printed parts made with this material exhibit high rigidity and low creep characteristics, providing the structural strength and stability required for automotive components. Additionally, the material has excellent adhesion, allowing easy integration with other materials to form composite structures and components with specific functionalities, achieving effective vibration damping and sound insulation.

Adhesive Material: Sika EVA material, a new type of environmentally friendly plastic foam material. This material features excellent cushioning, seismic resistance, thermal insulation, moisture resistance, and chemical corrosion resistance, making it widely used in automotive manufacturing.
