3D printing turbine

Material properties

Aluminum alloys combine lightweight and strength, and can withstand temperatures above 600°C . They possess excellent thermal conductivity, and their oxidation and corrosion resistance meet the requirements of demanding working conditions .

Technological advantages

Laser melting (SLM) metal 3D printing ensures that products can:
1. Create complex structures in one piece : directly print complex structures such as internal flow channels and thin-walled blades without the need for subsequent assembly, reducing assembly errors and potential failure points.

2. High precision: dimensional accuracy can reach ±0.1 mm, and layer thickness is controlled within 20–80 μm.

3. The R&D cycle has been significantly shortened: dimensional accuracy can reach ±0.1 mm, and layer thickness can be controlled between 20 and 80 μm.

4. High material utilization rate: The powder is recyclable, with a material utilization rate exceeding 95%.

Surface treatment

The roughness can be reduced to Ra < 3.2 μm through sandblasting, polishing, anodizing, etc., to improve wear resistance and fatigue resistance; it can also be treated with aluminizing, coating, etc. to enhance high temperature protection.

Application performance

1. Aerospace: It can withstand rotational speeds of tens of thousands of revolutions per minute and instantaneous high temperatures of over 1500°C .

2. Power equipment: Reduces weight by 20%–30% compared to traditional components, while improving thermal efficiency and response speed.

3. Reliability and lifespan: Density ≥99.5%, thermal fatigue life can reach more than 1.5 times that of traditional castings.
