Sciaky EBAM 88

The Sciaky EBAM 88 is an EBM 3D printer from Sciaky with a 1219 x 889 x 1600 mm build volume.

Specifications

Sciaky EBAM 88: Technical Specifications

Technology and Electron Beam

The Sciaky EBAM 88 uses DED-EB: a 42 kW electron beam at 60 kV accelerating voltage melts wire feedstock deposited in CNC-controlled layers. Identical beam system to the EBAM 68/110/150, in a larger chamber.

Work Envelope

1219×889×1600 mm (48×35×63 inches); chamber 88×88×110 inches: second-largest in the standard EBAM line.

Dual Wirefeed

The optional dual wirefeed enables simultaneous two-material deposition (bimetallic builds) or doubled deposition rates: a capability unique to Sciaky among commercial DED-EB systems.

IRISS Closed-Loop Control.

Calibration

Calibration of the EBAM 88

Chamber Vacuum

Larger chamber requires extended initial outgassing; target ≤1×10⁻⁵ Torr before beam enable.

Beam Calibration

Focus coil + 60 kV; test bead on target material; different parameters for Ti vs. Inconel.

Dual Wirefeed Synchronisation

With dual feeders active: check speed, position, and angle of both wires for a symmetric bead; asymmetry causes geometric distortion.

IRISS Baseline.

Common defects

Typical Defects on the EBAM 88

Gas Porosity

Cause: H₂/O₂ in wire; vacuum breach; moisture. Fix: certified wire; vacuum check; preheat substrate.

Dimensional Drift in Long Builds

Cause: thermal expansion along 1219 mm X-axis. Fix: IRISS CLC active; geometric checkpoints every 200–300 mm.

Bimetallic Delamination

Cause: uneven diffusion in dual-wirefeed transition zones. Fix: gradual composition ramp in transition regions; validate by metallographic cross-section.

What it is used for

Use Cases for the EBAM 88

Large Aerospace Structural Parts

Up to 1219 mm in X; Ti-6Al-4V at 100% material utilisation; replaces forging for small-to-medium series.

Bimetallic Components (dual wirefeed)

Functionally-graded Ti+Inconel parts: unique DED-EB capability at this scale.
