Sciaky EBAM 150

The Sciaky EBAM 150 is an EBM 3D printer from Sciaky.

Specifications

Sciaky EBAM 150, Technical Sheet

Technology: Wire-DED EBM, electron beam melts wire feedstock (not powder) under high vacuum.

Electron Beam: 42 kW at 60 kV; deposition rate 7–40 lbs/hr: claimed fastest in metal AM.

Build Volume: 2794×1575×1575 mm (110×62×62 in): among the largest commercial metal AM envelopes.

Vacuum: ≤1×10⁻⁵ Torr via High Efficiency Pumping; no inert gas required.

Wire Feed: Dual wire feeder (standard) for high deposition and bimetal builds.

Process Control: IRISS (Interlayer Real-time Imaging & Sensing System): closed-loop system monitoring and correcting bead width/height every layer.

Calibration

EBAM 150 Calibration

1. Pump-down to ≤1×10⁻⁵ Torr: before every build cycle; minimum 45 min for cold chamber. Verify with ionization gauge.

2. Beam focus & astigmatism: adjust focusing coils via Sciaky standard target; spot diameter within ±5% of nominal.

3. Wire feed rate: deposit reference bead; measure width ±0.5 mm and height ±0.2 mm vs. parameter library.

4.

Common defects

Typical Wire-DED EBM Defects

Surface porosity (EBAM150-D01): Unstable beam start/stop → use ramp-up/down functions and trim entry/exit zones in CNC finish.

Inter-layer delamination (EBAM150-D02): Insufficient inter-layer heat input or contamination → raise inter-layer temperature; verify vacuum integrity.

Geometric distortion (EBAM150-D03): Uneven cooling of large mass → alternate deposition direction; stress-relief heat treatment post-build.

What it is used for

Use Cases

Titanium aerospace structures: Spars and frames >2 m as single pieces; Buy-to-Fly <1.2 on Ti-6Al-4V.

Refractory and specialty alloys: Tantalum, tungsten, niobium: incompatible with powder beds, easily processed under vacuum.

Bimetal parts: Dual wire feed enables functionally graded parts in a single build cycle.
