Stellart Optics Nears IPO: How Domestic Laser Scanning Systems Drive the Upgrade of Additive Manufacturing Technology

Shenzhen Stellart Optics Technology Co., Ltd. (referred to as “Stellart Optics”), a high-tech enterprise specializing in the optical field, completed its IPO tutoring filing with the Shenzhen Securities Regulatory Bureau on January 30, 2026, with China International Capital Corporation (CICC) serving as its tutoring institution. This marks the official commencement of its IPO journey. This milestone holds significant exemplary value for domestic optical and laser equipment enterprises, further highlighting the strategic importance of homegrown core component technologies in advanced manufacturing, particularly in laser 3D printing and high-end laser processing.

Founded in 2017 as a domestic high-tech company, Stellart Optics has consistently focused on the research, development, and production of laser scanning galvanometers and their system solutions. It is one of the few local suppliers in the industry to offer a full range of galvanometer product lines. The company’s current products cover core components such as laser scanning heads (available in various sizes from 7 mm to 50 mm), motion control systems, encoders, and F-θ lenses, which are widely used in high-precision processing fields such as laser marking, cutting, welding, and additive manufacturing.

Laser Scanning Galvanometers: The “Invisible Core” of Additive Manufacturing

The laser scanning galvanometer system is one of the core components in modern laser equipment. Its primary function is to rapidly deflect the laser beam using high-speed oscillating mirrors, enabling precise energy distribution and motion control on the target surface. In traditional laser processing fields such as laser marking, engraving, and cutting, high-performance galvanometer systems have long been essential for improving processing speed and precision. This technology is equally critical for laser additive manufacturing equipment, such as SLA, SLS, and SLM 3D printing systems.

In metal or plastic additive manufacturing technologies like Laser Powder Bed Fusion (LPBF) and Selective Laser Sintering (SLS), high-speed and high-precision laser path control is fundamental to producing high-quality, geometrically complex components. By integrating high-performance galvanometers and control modules, printing equipment can achieve precise layer-by-layer material melting under conditions of higher scanning speeds and lower energy deviations, thereby improving surface quality, shortening molding cycles, and enhancing overall stability. This capability is particularly crucial in industrial applications.

Stellart Optics has made long-term investments in this area. According to industry information, the company has established a dedicated 3D printing project R&D team, developing galvanometer systems not only for traditional laser processing but also offering integrated solutions for metal printing systems and 3D processing platforms, including galvanometers, control cards, optical components, software, and algorithms. Its second-generation 3D printing system, “Sailing-3D,” is already in the R&D phase and set to be launched soon, signaling the company’s expansion from component supply to integrated system solutions.

Technical Advantages: High Precision and High Dynamic Response Are Key

A major strength of Stellart Optics’ products lies in the motion control capability and overall stability of its galvanometer systems. Such products typically include high-rigidity motion components, precision encoder feedback systems, and optimized control algorithms, enabling the laser beam to achieve micron-level positioning in an extremely short time and meeting the dual demands for speed and precision in laser processing.

Particularly in additive manufacturing scenarios, whether creating complex structures or intricate textures, the laser must maintain consistency across multiple scans along digital paths. Under high dynamic conditions, the galvanometer system’s response speed, stability, and anti-interference capability directly affect forming accuracy and printing consistency. Stellart Optics’ products have largely met industry-level requirements in these key metrics, laying a technical foundation for deeper collaboration with additive manufacturing equipment manufacturers.

Industry Chain Positioning: Import Substitution and Application Deepening

From an industry chain perspective, laser optical scanning systems are among the core supporting components of laser manufacturing equipment, and the long-standing dominance of foreign brands in this field has constrained the development of domestic high-end equipment. With breakthroughs by domestic companies like Stellart Optics in this sector, the localization rate of galvanometers and control systems has significantly improved. This helps reduce equipment costs, enhance supply chain stability, and supports the global competitiveness of domestic laser processing and additive manufacturing equipment.

Moreover, the maturity of such core components facilitates the exploration of innovative application scenarios. For instance, ultra-large-format 3D printing, high-speed precision laser cutting, and 3D laser engraving equipment all require higher standards in scanning and motion control. The stability and controllability of domestic core systems are expected to encourage equipment manufacturers to focus on overall performance optimization and the development of downstream industry application ecosystems.

Notably, Stellart Optics’ technological applications extend beyond additive manufacturing. According to official sources, its galvanometer systems are widely used in industries such as 3C electronics, photovoltaics, PCB, display panel processing, and micro-nano processing, demonstrating the products’ adaptability to diverse laser processing needs. This cross-scenario application has enabled the company to accumulate extensive engineering experience and expand the applicability of its technical solutions across different manufacturing systems.

In 2025, Stellart Optics also won a technological innovation award in the laser industry for its independently developed high-speed scanning series products, reflecting the gradual rise of domestic optical scanning technology in terms of market recognition and practical engineering applications.

Prospects: How Domestic Core Technologies Drive the Future of the Industry

The progress of Stellart Optics’ IPO is not only a necessary step for the company’s financing and expansion but also a microcosm of the localization process of core components in China’s manufacturing industry. As critical foundational components in industrial laser processing and additive manufacturing, the performance and reliability of laser galvanometer control systems will increasingly become key factors in enhancing equipment competitiveness.

With the widespread application of laser additive manufacturing technology in industrial manufacturing, aerospace, medical devices, and new materials, the demand for high-precision, high-dynamic-response laser path control continues to grow. The technological capabilities accumulated by Chinese manufacturers in this niche sector are gradually translating into industrial application value. In the future competitive landscape of domestic additive manufacturing equipment and laser systems, companies that master core component technologies are poised to wield greater influence.

As one of the leading enterprises in this trend, Stellart Optics’ continuous innovation in laser scanning control and integrated solutions holds significant potential to contribute to the technological advancement and market expansion of domestic laser additive manufacturing equipment.
