Technology & Products
Key Products
WAAM Equipment (STAR Series): AMmake S2 (Automated production), AMmake T1 (Research), AMmake A1 (Composite manufacturing), and AMmake R1 (Large-scale aerospace manufacturing); WLAM Equipment (Laser Series): Laser One (Industrial/Research), Laser Five, Robo L1 (Industrial platform), and Laser Mini (Desktop multi-laser wire-feeding printer); AMtwin: A full-process data management and digital twin software system for real-time monitoring and process traceability; VEAM Technology: Proprietary multi-laser coaxial wire-feeding technology for refined grain structure and high-precision printing; Services: 3D printing contract manufacturing (printing services), device services, and material process packages (24+ material types supported)
Technological Advantage
The core advantage lies in their proprietary VEAM (Multi-laser Coaxial Wire Feeding) technology and 8-axis linkage motion platforms, which enable high-speed, support-free printing of large structures. This is supported by their in-house software suite, including AMpath (CAM) and AMtwin (real-time process monitoring), ensuring quality consistency and stability during high-power (up to 15kW) printing.
Differentiation
Value Proposition
Rongsu Technology specializes in Directed Energy Deposition (DED) wire-feeding additive manufacturing, transitioning from first-generation Wire Arc Additive Manufacturing (WAAM) to second-generation Wire Laser Additive Manufacturing (WLAM). The company aims to make 3D printing costs competitive with traditional manufacturing within five years by offering high deposition efficiency (up to 8kg/h), high material utilization (3-5x improvement over traditional methods), and significantly reduced production cycles for large-scale industrial metal components.
How They Differentiate
Rongsu differentiates by evolving from first-generation Wire Arc Additive Manufacturing (WAAM) to second-generation Wire Laser Additive Manufacturing (WLAM). Their self-developed 'VEAM' (multi-laser coaxial wire feeding) technology allows for independent control of laser beams, achieving a surface roughness as fine as 5μm—significantly smoother than traditional arc-based systems. They also offer a unique range from desktop-level metal printers (Laser Mini) to massive 6-meter tall aerospace platforms (AMmake R1).
