Sciaky EBAM 68: Technical Specifications
Technology and Electron Beam
The Sciaky EBAM 68 uses DED-EB (Directed Energy Deposition: Electron Beam): a 42 kW electron beam at 60 kV accelerating voltage melts metal wire feedstock deposited in CNC-controlled layers. No powder is used: 100% of the raw material becomes part of the finished component.
Work Envelope
711×635×1600 mm: the smallest standard production EBAM, suited for medium-to-large structural parts.
Deposition Rate
7–40 lbs/hr (3–18 kg/hr) depending on material and geometry: claimed highest deposition rate in metal AM at its commercial launch.
IRISS Control.
Calibration of the EBAM 68
Vacuum and Chamber Outgassing
The chamber must reach ≤1×10⁻⁵ Torr before enabling the beam. New or infrequently used chambers require extended degassing with heated walls.
Beam Focus and Current Calibration
Focus coil and 60 kV accelerating voltage adjusted for an optimal melt pool diameter; a test bead on a sacrificial coupon of the target material validates the setting.
Wire Feed Rate Calibration
Feed rate vs.
Typical Defects on the EBAM 68
Gas Porosity
Cause: hydrogen/oxygen in wire feedstock; insufficient vacuum; moisture. Fix: aerospace-grade wire; vacuum and humidity checks.
Dimensional Drift
Cause: cumulative thermal expansion in long builds without IRISS compensation. Fix: enable IRISS CLC; add geometric control points in CAM.
Surface Roughness
Cause: bead-width variation at direction changes. Fix: add 1.5–3 mm machining stock on functional surfaces.
Use Cases for the EBAM 68
Aerospace Titanium Structural Parts
100% utilisation of expensive Ti-6Al-4V wire at high deposition rates (up to 40 lbs/h): replaces forging operations for small-series complex parts.
Repair and Material Addition
Direct deposition onto damaged Inconel and titanium components without disassembly.
