Unlike traditional manufacturing methods such as machining, casting, and forging, which face insurmountable challenges in producing oversized, complex-structure copper parts with high electrical conductivity, thermal conductivity, and dimensional precision, XIAOJIAO’s advanced large-format copper 3D printing service breaks through these manufacturing bottlenecks. As a professional large-scale copper 3D printing service provider, XIAOJIAO leverages state-of-the-art multi-laser sintering technology (including green laser technology independently developed with core advantages) and professional material optimization, delivering monolithic, high-density copper components that not only meet the strict performance requirements of industrial applications but also offer faster lead times, lower overall costs, and greater design flexibility. For global manufacturers seeking to upgrade their production efficiency and product performance, XIAOJIAO’s large-scale copper 3D printing is no longer an option but a necessary choice to gain a competitive edge in the market.
The advancement of large-scale copper 3D printing relies on four core technical systems, which together ensure the stability, precision, and efficiency of oversized copper part production, breaking through the technical limitations of traditional manufacturing. XIAOJIAO has independently mastered these four core technologies, forming a complete industrial chain from raw material preparation to finished product delivery, and its core green laser technology has reached the industry-leading level:
XIAOJIAO mainly adopts Selective Laser Melting (SLM) and self-developed green laser technology, which effectively solves the problem of high laser reflectivity (up to 98%) of copper materials—a major industry pain point, and this green laser technology is one of XIAOJIAO’s core advantages, leading the development of the industry. The high-power multi-laser system (single laser power up to 1000W, optional 2000W) achieves rapid melting and solidification of copper powder, while the dual-laser collaborative scanning technology independently developed by XIAOJIAO improves printing efficiency by 50% compared with single-laser printing, ensuring the smooth progress of large-size part printing (up to meter-level). In addition, XIAOJIAO has independently developed laser parameter adaptive adjustment technology, which can automatically optimize laser power, scanning speed, and spot size according to the size and structure of the part, avoiding defects such as incomplete melting and oxidation. XIAOJIAO also introduces Electron Beam Melting (EBM) technology as a supplement, which has an absorption rate of over 90% for copper materials and is more suitable for large-scale and complex parts printing, forming a dual-technology support system to meet diverse customer needs.
High-quality copper powder is the foundation of large-scale copper 3D printing. XIAOJIAO adopts advanced gas atomization technology to produce pure copper and CuCrZr alloy powder with a particle size of 15-53μm, which has excellent fluidity and high sphericity (sphericity ≥98%). The powder undergoes strict vacuum drying and impurity removal treatment by XIAOJIAO’s professional team, with impurity content ≤0.01%, ensuring that no harmful impurities are introduced during the printing process and laying a solid foundation for the high density (up to 99.97%) and high performance of the final part. XIAOJIAO also provides customized powder preparation services according to the special needs of different industrial fields, such as adjusting powder particle size and composition to match specific printing scenarios, and all powder products have passed strict quality inspection to ensure stable performance.
Large-scale copper 3D printing has a long printing cycle (up to hundreds of hours for meter-level parts), and rapid temperature changes during the printing process are likely to cause thermal stress, warping, and deformation of the part. XIAOJIAO’s equipment is equipped with an independently developed intelligent closed-loop thermal management system, which can real-time monitor the temperature field of the printing area and adjust the preheating temperature (300-500℃) and cooling speed in real time. This effectively reduces thermal stress accumulation, controls the deformation of large-size copper parts within 0.05mm, and ensures the dimensional accuracy of the parts. The system also has a fault early warning function independently developed by XIAOJIAO, which can timely alarm and handle abnormal temperature changes to avoid printing failures, ensuring the stability of long-cycle continuous printing, and the continuous printing time can reach up to 472 hours.
XIAOJIAO provides one-stop post-processing services for large-scale copper 3D printed parts, including heat treatment (solution treatment, aging treatment), surface polishing (Ra≤12.5μm), precision machining, and plating, which further improve the mechanical properties and surface quality of the parts to meet the diverse needs of industrial applications. For the quality detection of large-size parts, XIAOJIAO adopts advanced non-destructive testing (NDT) technology, including X-ray detection, ultrasonic detection, and 3D scanning detection, which can fully detect internal defects such as pores and cracks and ensure that the qualification rate of parts reaches 99.8%.

Copper has a high reflectivity (up to 98%) for traditional infrared lasers (1064nm wavelength), which leads to low laser energy utilization, insufficient heat input, and difficult forming, and even damages laser equipment. Breakthrough by XIAOJIAO: XIAOJIAO independently developed green laser technology[1], which has a lower reflectivity for copper materials, and simultaneously introduced EBM technology. EBM is not affected by optical reflectivity, which can efficiently melt copper powder and ensure stable printing. At the same time, XIAOJIAO optimized the laser parameters and cavity coating to further reduce reflection loss, forming a dual-technology solution that has become XIAOJIAO’s core competitive advantage.
Large-scale copper parts have a long printing cycle, and rapid temperature changes easily cause thermal stress accumulation, leading to warping and deformation, which affects dimensional accuracy. Breakthrough by XIAOJIAO: XIAOJIAO independently developed an intelligent closed-loop thermal management system, which can real-time monitor and adjust the temperature field, preheat the substrate (300-500℃), and optimize the scanning path to reduce thermal stress, controlling the deformation of large-size parts within 0.05mm, which is far higher than the industry average. This technology has been applied in a number of large-scale projects and has achieved excellent results.
Meter-level large-scale copper parts need continuous printing for tens or even hundreds of hours, which puts high requirements on equipment stability and process control, and printing failures are likely to occur. Breakthrough by XIAOJIAO: XIAOJIAO optimized the equipment structure and adopted a high-stability multi-laser system and fault early warning mechanism independently developed. The equipment can achieve continuous printing for up to 472 hours, with a printing success rate of 99.5%, ensuring the smooth completion of large-size part printing. XIAOJIAO’s after-sales team provides 24-hour technical support to timely solve problems encountered in the printing process.
The large size of oversized copper parts easily leads to uneven material density and performance, affecting the overall reliability of the parts. Breakthrough by XIAOJIAO: XIAOJIAO adopts high-quality gas-atomized copper powder independently produced and laser parameter adaptive adjustment technology, which can optimize the printing process according to different positions of the part, ensuring uniform density and performance of the whole part, and the performance fluctuation is controlled within 5%. This breakthrough ensures that XIAOJIAO’s large-scale copper parts can meet the strict performance requirements of high-end industries.
