Jam‑5200Ebm Electron Beam Metal 3D Printer

The JAM‑5200EBM is an electron‑beam powder‑bed‑fusion 3D printer using JEOL's electron‑beam control technology from electron microscopes and semiconductor lithography systems. The system employs a 6 kW high‑power electron beam to produce high‑density and high‑strength metal parts. The hot process uses electron‑beam preheating to eliminate distortion and cracking, reducing residual stress compared to laser‑based additive manufacturing. The high‑vacuum environment prevents oxidation and reduces impurities, which is particularly beneficial for active metals such as titanium alloys. A backscattered‑electron (BSE) image monitoring function enables real‑time in‑situ process monitoring for defect detection layer by layer. The system features automatic electron‑beam correction for focus, astigmatism, and position distortion. The building range extends up to Φ250 mm × 400 mm (H). The JAM‑5200EBM produces parts that meet regulated industry standards for serial production scaling.
