3D printing centrifugal wheel

Material properties

Aluminum alloy has a density of only 2.68 g/cm³ , making it relatively lightweight. It has a tensile strength ≥320 MPa, a yield strength ≥220 MPa, is corrosion resistant, and maintains dimensional and performance stability within a temperature range of -40℃ to 200℃ .

Technological advantages

Selective Laser Melting (SLM) 3D printing ensures products can:
1. Create complex, integrated structures : No welding, riveting, or assembly is required; directly print a complete structure including hubs, blades, and fairings.

2. Design freedom : Accurately matches fluid dynamics simulation results, significantly improving aerodynamic efficiency.

3. High material utilization rate : The utilization rate reaches over 95%, which greatly reduces raw material waste and is especially suitable for small-batch, customized production.

4. Rapid iteration : The cycle from design optimization to finished product delivery is shortened by 70%, accelerating product upgrades.

Surface treatment

After printing, the surface roughness Ra is 6.3-12.5μm, which can be precision polished, anodized, passivated or sprayed to form a dense protective layer and extend the service life in harsh environments.

Application performance

1. High-efficiency fluid transport : Customized blades improve aerodynamic efficiency by 10%-15%, achieving greater air volume or lower energy consumption at the same power.

2. High-speed and stable operation : It can support high-speed rotation of over 10,000 rpm without the risk of fatigue fracture.

3. Low noise and low vibration : Precise blade design and dynamic balance correction reduce airflow noise and mechanical vibration.

4. Adaptable to extreme environments : It can be applied to harsh working conditions such as high temperature, high humidity, and corrosive gases, such as industrial dust removal, aviation air conditioning, and ship ventilation.
