TCT Asia was a great opportunity to connect with Chinese AM vendors pushing the boundaries of innovation. With over 450 exhibitors and 36,000 pre-registered visitors, the event showcased the latest advancements from leading Chinese AM companies—many of which specialize in Metal AM systems for manufacturing applications.
Among the numerous Laser Powder Bed Fusion (LPBF) solution providers at the show, one company stood out—Addireen Technologies, China's first provider of industrial Metal AM systems utilizing green-laser technology. What sets Addireen apart from other Metal AM manufacturers, and what advantages does green-laser technology offer? I visited their booth to find out.

Addireen is a Shenzhen-based company founded in 2023 by its Chairman, Dr. Fan Zhang—the visionary behind the company's technology. A local entrepreneur with a Ph.D. in Engineering, Dr. Zhang has held several academic positions at leading universities in China.
The company's leadership team includes CEO Mr. He Xiangrong, who brings experience from multiple high-tech companies, including the AM company Eplus3D, and CTO Dr. Liang Guowen, an expert in precision 3D printing of highly reflective metals.

Addireen’s proprietary green-laser technology—the first of its kind in China—significantly enhances the efficiency, quality, and precision of additive manufacturing for highly reflective metals, refractory metals, and conventional metals alike. Unlike existing European/American green laser solutions on the market, it is based on a single mode, high powder with high laser beam quality (M2≤1.1).
The company’s primary goal is to tackle key industry challenges while expanding the range of possible applications. By enabling a broader selection of materials, increasing printing efficiency, reducing costs, and simplifying post-processing, Addireen aims to provide industrial 3D printing solutions that scale metal AM to mass production.
Why Is Green Laser Technology So Special?
One of the key limitations of standard infrared lasers is their wavelength—where shorter wavelengths result in higher absorption rates. This limitation restricts the range of usable materials and negatively impacts final print quality, particularly for unique metals such as copper, gold, and silver. Standard infrared lasers can lead to reduced material density, increased porosity, and diminished thermal and electrical conductivity in these materials.
To overcome these challenges, Addireen has developed a unique green-laser technology that delivers superior performance when processing materials with high reflectivity and thermal conductivity. Its high-power, single-mode continuous fiber green laser offers several key advantages, including shorter wavelengths, high beam quality, exceptional stability, and finer focal spots. These features result in greater forming efficiency, improved print quality, and higher resolution.

Addireen’s green laser advantages
What are the advantages of the company’s AM technology compared with traditional infrared lasers?
Enhanced Efficiency with Highly Reflective Metals: Traditional infrared lasers often struggle with materials like pure copper due to low absorption rates, leading to inefficiencies. Green lasers, however, have higher absorption rates with these metals, facilitating more efficient and precise printing.
Improved Print Quality: The smaller spot size of green laser, min to 15μm, allows for finer details and smoother surfaces in printed components. This precision is particularly beneficial for applications requiring intricate designs and high-quality finishes.
Versatility Across Materials: Beyond pure copper, green laser technology is effective with other highly reflective and refractory metals, including gold, silver, platinum, tantalum, and tungsten. This versatility expands the range of materials that can be additively manufactured with high quality.
Reduced Spattering and Increased Stability: The high energy absorption of green lasers minimizes spattering during the melting process, leading to more stable and continuous operations. This reduction in spatter contributes to the longevity and reliability of the printing equipment.
Product portfolio
Addireen offers four distinct 3D printing systems, ranging from a smaller model to its largest system, which made its debut at TCT Asia. The primary differences between these models lie in their build tray sizes and laser power options. All systems leverage the company’s proprietary green-laser technology, enabling the printing of copper, precious metals (gold, platinum, silver 925), as well as highly reflective and refractory materials.

At the event, Addireen showcased its full-spectrum green-laser metal 3D printing solutions, covering lasers, printing equipment, and control software—all developed in-house.
During the show, the company introduced the XH-M660G, a cutting-edge multi-laser 3D printing system featuring a build volume of 660 × 660 × 1300 mm and a maximum print height of 1.2 meters (excluding the substrate). Equipped with four green lasers, the XH-M660G overcomes traditional challenges associated with printing highly reflective and refractory metals, particularly pure copper and copper alloys. This system provides a comprehensive industrial 3D printing solution for manufacturing applications.
