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.
Market & Competition
Target Customers
Metal AM machine OEMs and high-end industrial end-users in aerospace and medical sectors requiring rigorous quality assurance.
Industry Verticals
Aerospace; Automotive; Medical; Energy
Competitors
Sigma Additive; Plasmo (6K Additive); Stratonics
