Technology & Products
Key Products
AMmake T1 (Wire Arc Additive Test Platform); WLAM Series (Laser Wire Additive Manufacturing Systems); WAAM Series (Wire Arc Additive Manufacturing Systems); Rongsu Cloud Control Software
Technological Advantage
Uses standard welding wire which is 10-20x cheaper than specialized AM powders; achieves deposition rates of 2-10kg/hr vs 0.1-0.5kg/hr for LPBF.
Differentiation
Value Proposition
Reduces the cost of large-scale metal part production by up to 60% compared to powder-bed fusion while increasing deposition rates by 10x, enabling rapid production of structural aerospace components.
How They Differentiate
Offers a specialized research-to-production pathway with the AMmake T1 platform, allowing customers to develop processes on a small scale before moving to large-format industrial WLAM/WAAM systems.
Market & Competition
Target Customers
Aerospace and defense manufacturers, research institutions, and energy sector structural engineers.
