Since its establishment in 2005, KT has grown into a leading provider of advanced 3D printing services, specializing in the production of high-performance components for industries such as aerospace, robotics, automotive, and industrial automation. With a state-of-the-art additive manufacturing facility, KT utilizes technologies such as SLA, SLS, and metal 3D printing to produce complex geometries, lightweight structures, and high-precision functional parts.
Core Characteristics
- Hybrid manufacturing advantages: 3D printing realizes complex hollow lightweight structures, CNC finishing ensures high assembly precision;
- Extreme lightweight design: bionic wavy hollow structure, greatly reduces weight without sacrificing structural strength;
- Excellent mechanical properties: 7075 aviation aluminum with high fatigue & vibration resistance;
- Unique structure: cannot be integrally manufactured by pure traditional CNC machining;
- High-precision assembly: critical features finished by CNC, tolerance up to ±0.02mm.
Technical Process
Adopt SLM Selective Laser Melting Metal 3D Printing + 5-Axis CNC Finishing Hybrid Manufacturing Process:
- Bottom wavy hollow lightweight structure: integrally formed by SLM 3D printing, internal hollow area is unreachable for CNC tools;
- Upper precision mounting holes, datum surfaces & fitting cavities: finished by 5-axis CNC milling, meeting aerospace-grade dimensional tolerance and surface quality;
- One-piece molding without welding seams, weight reduced by more than 40% compared with traditional forged CNC parts.
