EBAM 3D Printing Service: Large-Scale Superalloy Part Manufacturing with High Efficiency
Introduction
Electron Beam Additive Manufacturing (EBAM) is a high-efficiency additive manufacturing process ideal for producing large-scale superalloy parts with precision and reliability. EBAM rapidly deposits and solidifies metal wire feedstock using an electron beam as a heat source, including advanced alloys like Inconel 718 and Ti-6Al-4V. The technology achieves deposition rates up to 10 kg/hour, enabling rapid production of massive components without compromising material integrity.
Compared to traditional forging or casting, EBAM reduces material waste by over 60%, significantly shortens lead times, and optimizes the mechanical properties of large, complex metal structures.
