Technology & Products

Key Products

AI-powered laser inspection and processing technologies for quality assurance in metal additive manufacturing systems and high-precision industrial applications.

Technological Advantage

Proprietary coaxial optical path design (Patented) allows for high-resolution, distortion-free monitoring of the melt pool directly through the laser delivery system, which is more accurate than off-axis thermal imaging. Claimed closed-loop control capability is verified by integration with major Chinese aerospace OEMs.

Differentiation

Value Proposition

AI-driven quality control for mission-critical AM components

How They Differentiate

Achieves 100kHz sampling rates for melt pool monitoring, 2.5x faster than Sigma Additive's PrintRite3D, at a lower price point for the Chinese industrial market.

Why this company matters

Diligine Photonics provides AI-powered laser inspection and processing technologies for quality assurance in metal additive manufacturing. The company focuses on real-time melt pool monitoring for LPBF and DED systems, addressing a critical gap in process control for mission-critical components in aerospace and other high-precision industries.

The core technology is a proprietary coaxial optical path design that enables high-resolution, distortion-free monitoring of the melt pool directly through the laser delivery system. This architecture achieves 100kHz sampling rates for real-time defect recognition, which the company claims is 2.5x faster than comparable solutions from Sigma Additive. The system's closed-loop control capability has been verified through integration with major Chinese aerospace OEMs.

Diligine Photonics serves metal AM machine OEMs and end-users in aerospace, automotive, medical, and energy sectors. Named customers include AECC (Aero Engine Corporation of China) and COMAC, indicating traction in domestic aerospace quality assurance. The company also collaborates with South China University of Technology and Huazhong University of Science and Technology on research and development.

The company's competitive position is strengthened by a portfolio of over 50 patents covering coaxial monitoring and defect detection methods. Key investors include CasStar, Guangzhou Hi-tech Investment, and CEC Capital, with total funding of approximately $15 million. The primary competitive risk is that global players like Plasmo (6K Additive) and Stratonics may offer more established solutions outside China, while Diligine's lower price point and domestic partnerships provide a moat in the Chinese industrial market.
