How does NewayAero ensure quality of its SLM-printed Inconel 718 parts?
Powder and Process Control
NewayAero uses aerospace-grade Inconel 718 powder with strict control over particle size distribution, oxygen content and flowability. During SLM 3D printing, parameters such as laser power, scan speed and layer thickness are carefully monitored to maintain consistent melt pools and prevent defects like balling or incomplete fusion.
Post-Processing for Mechanical Strength
To achieve full density and high fatigue resistance, all printed Inconel 718 components undergo hot isostatic pressing (HIP) and heat treatment. These processes enhance γ′/γ″ precipitation, close residual porosity and stabilize the microstructure for long-term reliability in demanding environments.
Precision Finishing
Critical features such as sealing faces, threads and mounting areas are refined using EDM or CNC machining. This ensures tolerance accuracy and prevents stress concentration, meeting aerospace-grade fit and finish requirements.
Inspection and Certification
Extensive material testing and analysis—including CT scanning, metallography and mechanical testing—is conducted to verify density, microstructural consistency and fatigue performance. For applications in aerospace and power generation, components are provided with full traceability records and certification documentation.
