Additive Manufacturing Gas Turbine Blades – One-Stop 3D Printing & Professional Post-Processing Service

Integrated Forming of Ultra-Complex Cooling Structures | Full-Range Precision Post-Processing for High-End Power Components

1       Core Product: Metal 3D Printed Gas Turbine Blades

The sample shown in the picture is an aero/industrial gas turbine single-crystal blade fabricated via high-performance Inconel based alloy additive manufacturing, breaking through the limitations of traditional forging and casting processes:

1.1      Integrated Forming of Ultra-Thin Film Cooling Micro Holes

Rows of micron-level cooling tiny holes along the blade airfoil are printed in one piece without secondary deep hole drilling. Complex internal cooling channels, serpentine flow paths and turbulator structures are manufactured in a single run, drastically improving the blade’s high-temperature heat dissipation, raising the turbine’s maximum heat resistance and power output.

1.2      Integrated Manufacturing of Complex Fir-Tree Roots & Contoured Airfoils

Multi-tooth fir-tree roots, tapered high-curvature airfoils and damping platforms are printed monolithically, eliminating stress weak zones caused by segmented welding or forging splicing in conventional production. Structural strength and high-temperature fatigue life of components are significantly enhanced.

1.3      Compatible with Full Range of Inconel based alloy Powders

Custom printing available for aerospace-grade superalloys including In625, In536, GH4099, Inconel 718 and René108, applicable to Stage 1/2 rotating and guide vanes of heavy-duty gas turbines and aero-engines.

2       Core Advantages: One-Stop Custom 3D Printing Service

2.1      Full-Cycle Custom Printing Service – From Drawings to As-Printed Blanks

n  Front-End DfAM Design Collaboration: Professional additive manufacturing engineers support early-stage blade R&D. We optimize printing supports and scanning strategies for cooling channels and thin-walled airfoils to resolve common defects like warpage and cracking in large aspect ratio thin-walled blades.

n  Dual Solutions for Prototyping & Mass Production: Fast sample delivery within 72 hours for single R&D prototypes, and stable mass supply for batches of hundreds, catering to iterative research of research institutes and serial production supporting for OEMs.

n  Controllable Dimensional Accuracy: Overall blade profile tolerance ±0.05 mm, cooling micro-hole dimensional tolerance ±0.02 mm, complying with Class 1 precision standards for power components.

n  Full Traceability of Raw Materials: Domestic & imported aerospace-grade metal powders supplied with complete inspection documents covering particle size, oxygen content and material certification.

2.2      Industry-Leading Complete Precision Post-Processing Capacity (Core Competitive Edge)

We deliver more than just as-printed blanks. Our dedicated full post-processing production line for turbine blades solves typical AM pain points including rough surface texture, residual stress and substandard mechanical performance:

2.2.1   Hot Isostatic Pressing (HIP) & Vacuum Heat Treatment

Densification treatment eliminates internal pores in printed blades, relieves residual printing stress and homogenizes superalloy metallurgical microstructure. High-temperature rupture strength and creep resistance reach equivalent performance of forged parts.

2.2.2   5-Axis CNC Precision Milling for Airfoils & Fir-Tree Roots

High-precision milling and grinding for blade roots and mounting datums to guarantee assembly fit tolerances; profile finishing of contoured airfoils to perfectly match aerodynamic design geometry.

2.2.3   Chemical Polishing & Abrasive Flow Machining (AFM) for Smooth Internal Microchannel

Internal complex cooling passages and film holes are polished to remove trapped powder and step texture, lowering airflow resistance and preventing carbon buildup blockage at high temperatures. External blade surfaces can be finished to mirror quality to boost aerodynamic efficiency.

2.2.4   Integrated High-Temperature Protective Coating Solutions

Complete coating services including Thermal Barrier Coatings (TBC), Al-Si diffusion coatings and anti-oxidation overlay coatings to mitigate high-temperature oxidation and hot corrosion failures of gas turbine blades.

2.2.5   Complete Non-Destructive Testing (NDT) Support

Post-print and post-processing inspections include CT scanning of internal cooling channels, fluorescent penetrant inspection, X-ray porosity detection and CMM geometry scanning. Full inspection reports are issued to meet acceptance specifications for aerospace power components.
