WAAM 3D Printing Service: Fast & Affordable Large Superalloy Component Fabrication
Introduction
Wire Arc Additive Manufacturing (WAAM) is a cost-effective metal additive manufacturing technique ideal for fabricating large-scale superalloy components rapidly and economically. Utilizing an electric arc to deposit metallic wire feedstock, WAAM efficiently produces robust, high-density parts from alloys like Inconel 625 and Hastelloy X at deposition rates of up to 10 kg/hour.
Compared to traditional forging or machining, WAAM reduces production time by over 60%, material waste by approximately 70%, and overall costs significantly, making it ideal for industrial-scale manufacturing.
