Presentation of the equipment's characteristics
The Greenstone GSTCP-Series Supersonic Low-Pressure Cold Spray Additive Manufacturing System, developed by Greenstone-Tech, is an advanced solid-state metal additive manufacturing solution based on gas-dynamic cold spray technology.
By accelerating metal powder particles to supersonic velocities using a low-pressure gas source, the system enables high-density metal deposition without melting, completely avoiding thermal degradation, oxidation, or phase transformation. This makes the GSTCP-Series ideal for metal additive manufacturing, precision repair, and functional coating applications in aerospace, transportation, energy, electronics, and heavy industry.
Unlike traditional thermal spray or fusion-based additive manufacturing processes, the Greenstone cold spray system delivers high deposition efficiency, excellent bonding strength, and precise thickness control, while significantly reducing energy consumption and operational costs.
1. Supersonic Low-Pressure Cold Spray Technology
The Greenstone GSTCP-Series utilizes a supersonic gas-dynamic acceleration mechanism under low operating pressure, achieving particle velocities sufficient for solid-state bonding while minimizing system energy demand.
No melting, no heat-affected zone (HAZ)
No oxidation or phase change
Stable and repeatable deposition quality
2. High Deposition Efficiency and Thickness Control
The system supports thick-layer deposition in a single pass, enabling rapid material buildup for additive manufacturing and repair.
Layer thickness per pass increased by over 300%
Deposition efficiency up to 3× higher than conventional processes
Suitable for both near-net-shape AM and precision repair
3. Energy-Efficient and Environmentally Friendly
Operating with a low-pressure gas supply, the GSTCP-Series significantly reduces power consumption while maintaining industrial-grade performance.
Low gas consumption
Reduced operating and maintenance costs
Green and sustainable manufacturing process
4. Wide Material Compatibility
The system supports a broad range of metal and composite materials, including:
Aluminum and aluminum alloys
Copper and copper alloys
Nickel-based materials
Titanium and titanium alloys
Metal–metal and metal–ceramic composite powders
This versatility allows one system to serve multiple production and repair scenarios.
5. Intelligent Integrated Control System
Greenstone integrates powder feeding, gas control, motion control, and process monitoring into a fully integrated intelligent control platform.
Proprietary powder feeder with adjustable flow rate (140%–438% range)
Multiple nozzle configurations for different applications
Real-time parameter control and process stability
Compatible with robotic and automated systems
6. Ideal for Additive Manufacturing and Precision Repair
The solid-state nature of cold spray makes the GSTCP-Series especially suitable for:
Large-scale metal additive manufacturing
