At 8:00 PM on November 9, 2025, the 15th National Games of China officially opened with great ceremony at the Guangdong Olympic Sports Center in Guangzhou. In this grand sporting event that showcased the caliber of "Intelligent Manufacturing in China," the National Games torch, named "Blossom," became a focal point with its intricate design — a striking testament to the comprehensive enabling power of metal 3D printing technology.

The twisting, precision-interwoven petals "blooming" at the top of the torch not only symbolize the integrated flourishing of Guangdong, Hong Kong, and Macao, but also embody the technical strength of Han's Focus in the field of metal 3D printing. As a key participant in the project, Han′s Matrix3D applied its metal 3D printing technology to provide critical technical support for the precision forming of this complex structure.

As the most challenging core component in the manufacturing of the torch, the production of the petal structure perfectly demonstrates Han's Focus's professional capabilities in the field of metal 3D printing.

INTEGRATED PRECISION FORMING

The spatially twisted petals of the "Blossom" torch form a typical complex, non-uniform structure — precisely where the core advantages of 3D printing technology shine.

 Driven by digital models, this technology enables the integrated forming of the spatially twisted petals, ensuring the complete realization of complex spatial geometries and fine features. This holistic manufacturing approach not only enhances the structural strength of the component but also achieves precise translation of the design intent.

PRECISION ASSEMBLY OF DISSIMILAR MATERIALS

To balance the torch's lightweight requirements with high-temperature resistance, the R&D team leveraged metal 3D printing technology to achieve an innovative material combination strategy. The main body is made of aluminum alloy for weight reduction, while the top combustion zone is fabricated using heat-resistant stainless steel.

After heat treatment, the assembly precision of the dissimilar material components is consistently controlled within ±0.1mm, fully validating the precise controllability of this technology in multi-material composite manufacturing. Through precise material distribution and structural optimization, this approach achieves optimal resource allocation while ensuring product functional reliability, setting a new benchmark for lightweight design and performance enhancement in high-end equipment.

EFFICIENT INTELLIGENT MANUFACTURING

Through the innovative application of multi-laser collaborative printing technology, a dual breakthrough in both efficiency and precision was achieved in the manufacturing of the torch's petal structure. This technical solution successfully reduced the production cycle from several weeks required by traditional processes to just 72 hours. While maintaining micron-level manufacturing precision, it significantly enhanced mass production efficiency, providing reliable technical support for the achievement of key project milestones.

The manufacturing process of the National Games torch "Blossom" has validated the practical value of metal 3D printing technology in the field of complex components. These practice-proven technical solutions are now being applied and transformed across sectors such as medical devices, automotive parts, and precision molds. 

Han′s Matrix3Ds looks forward to joining hands with more industry partners to help enterprises solve manufacturing challenges, improve production efficiency, and jointly drive the transformation and upgrading of the manufacturing industry through 3D printing technology.
