Metal additive manufacturing technology, as a core driving force reshaping the modern industrial landscape, is deeply integrated into key manufacturing processes in critical fields such as aerospace, energy power, and automotive manufacturing. The Xin Jinghe LiM-X800 series large-scale metal 3D printing equipment, with its ultra-large forming space, groundbreaking process innovations, and production stability, effectively addresses the core challenges of manufacturing precision, production efficiency, and overall costs for large and complex components, providing momentum for large-scale industrial manufacturing.
At the same time, the rapid development of national strategic industries such as aerospace, shipping, and rail transportation has raised higher requirements for the comprehensive performance, processing accuracy, and production efficiency of large metal 3D printing equipment, directly driving the rapid development and iteration of equipment with meter-level specifications and above.
After years of technological accumulation and product development, Xin Jinghe has formed a relatively complete equipment matrix with a forming area of 800mm × 800mm: The LiM-X800 device was launched in 2022, providing strong equipment support for the manufacturing of components in the aerospace and automotive sectors; in 2023, the LiM-X800H device was prominently launched at the TCT ASIA exhibition, focusing on the forming needs of large-sized long-axis components, increasing the forming height to 1660mm (including a standard substrate thickness of 80mm); in 2024, based on deep market insights, the meter-level device LiM-X800H+ will be launched, with a Z-axis net forming height of 2500mm, achieving integrated manufacturing of ultra-large components and providing better solutions for oversized/long-axis components in aerospace.
In the field of aerospace component manufacturing, the LiM-X800 series equipment effectively addresses the manufacturing challenges of large and complex components in terms of forming size, processing accuracy, and overall performance.
Relying on the large-size LiM-X800H equipment, Xin Jinghe manufactures high-temperature alloy aerospace engine pre-swirl nozzles (φ754mm × 151mm), which adopt a large-volume lattice structure design, precisely removing solid structures in non-critical areas to achieve lightweight goals.
Faced with such large-sized thin-walled components containing complex lattice cavities, traditional manufacturing processes are difficult to process, have high waste, and struggle to ensure structural integrity and consistency. Metal 3D printing solutions eliminate the need for molds, simplifying the production process, improving material utilization, and effectively controlling overall costs. The precise lattice structure provides excellent energy absorption characteristics for the pre-swirl nozzle, making it particularly effective in dissipating the impact and shock loads caused by high-speed airflow from the engine, ensuring reliable performance for critical aerospace components.
LiM-X800H equipment prints critical components of aerospace engine casings (φ715mm × 300mm), which are made of high-temperature alloy materials, featuring an overall annular structure, large dimensions and complex profiles, with thin walls and weak rigidity. The final product exhibits good fluid dynamics performance, high strength, and durability.
Using 3D printing methods, the challenges of processing high-strength materials such as high-temperature alloys are overcome, simplifying complex processing steps, and allowing for direct printing. This not only significantly improves material utilization but also greatly accelerates the R&D speed of aerospace components, enabling rapid optimization and iteration of design solutions.
LiM-X800H+ continues the excellent performance of LiM-X800H, breaking through the Z-axis net forming height to 2.5m, further enhancing the height of formable components. The equipment successfully printed ultra-high spiral structural components, measuring 418mm × 362mm × 2210mm. This component is made of lightweight high-strength TA15 titanium alloy, ensuring the strength performance of the part while weighing only 22kg.
LiM-X800H+ continuously and stably printed for 305 hours in integrated formation, fully demonstrating the process stability and reliability of the equipment, providing strong technical validation for the rapid manufacturing of oversized, lightweight structural components in aerospace and large molds.
In automotive parts manufacturing, the customized LiM-X800 equipment prints automotive connecting brackets across the full surface, showcasing the significant advantages of metal 3D printing technology in mass production. The component’s overall dimensions are 770mm × 790mm × 235mm (excluding the substrate), with a single piece measuring 42mm × 115mm × 131mm. Using an 80μm large layer thickness process, 240 automotive connecting brackets were printed in just 112 hours, achieving efficient multi-layer batch printing, reducing the production cycle by 20% and lowering production costs by over 60%. The LiM-X800 achieves integrated printing and forming of high-performance automotive connecting brackets, aiding in the increase of production efficiency in the automotive manufacturing sector.
At the same time, the high flexibility of 3D printing technology demonstrates more advantages during the design and R&D phase of automotive components: breaking free from the limitations of traditional processes, granting great freedom in design; enabling direct manufacturing without the need for molds, compressing the prototype verification cycle from “weeks” to “hours”, significantly reducing the development costs of repeatedly verifying and iterating parts; while ensuring rapid manufacturing, it also guarantees the precision and flexibility of the products.
The LiM-X800/800H/800H+ equipment, through continuous technological iteration and innovative applications, constantly breaks through the manufacturing limitations of large and complex metal components, providing efficient, precise, and economical additive manufacturing solutions for strategic industries such as aerospace and automotive manufacturing. In the future, Xin Jinghe will continue to focus on the R&D of large-scale metal 3D printing equipment, providing more efficient and stable solutions for the high-end manufacturing industry with more advanced technologies and more reliable products, driving industrial innovation and high-quality development.
