Specifications

Sciaky EBAM 200, Technical Sheet

Technology: Wire-DED EBM with internal boom-mounted electron gun, unique architecture enabling very long horizontal parts.

Electron Beam: 42 kW at 60 kV; High Efficiency Pumping to ≤1×10⁻⁵ Torr.

Build Volume: 4064×1194×1524 mm (160×47×60 in); chamber 200×110×110 in.

Deposition Rate: 7–40 kg/hr depending on material and geometry.

Process Control: IRISS + CNC Joint Scanning & Digitizing System for automated bead placement.

Wire Feed: Dual wire feeder for bimetal and high-deposition applications.

Accuracy: ±1.5 mm near-net shape; CNC finish machining mandatory.

Calibration

EBAM 200 Calibration

1. Vacuum pump-down: larger chamber requires 60–90 min; check door seals on extended perimeter.

2. Boom alignment: position and calibrate stand-off ±3 mm across full 4 m X-axis.

3. Focus by position: correction table for focusing coils at different X-axis positions.

4. IRISS baseline reset: zero with positional correction data; test bead with no correction warnings.

5. CMM verification: test coupon covering ≥80% of X length; deviation ≤±1.5 mm.

Common defects

Typical Defects

Axial geometric distortion (EBAM200-D01): Non-uniform thermal history → stand-off correction table + support ribs.

Non-uniform bead width (EBAM200-D02): Boom drift → IRISS positional correction + reduced speed at ends.

Cold-zone delamination (EBAM200-D03): Cold extremities → preheat scan before each layer.

Oxidation contamination (EBAM200-D04): Micro-leaks on large perimeter → He leak check + RGA monitoring.

What it is used for

Use Cases

Horizontal aerospace structures >4 m: Unique system for wing spars and frames as single pieces.

Marine structural components: Beams, plates, hulls as single pieces without welded assembly.

Refractory alloys: Tantalum, tungsten, niobium under vacuum without oxidation.

Bimetal graded parts: Dual wire feed enables material transition along part length.
