Wire feedContinuous wire feedstock
A spool of metal wire (titanium, steel, etc.) feeds into the vacuum chamber at a controlled rate, typically 1–4 meters per minute.
Electron beamElectron beam melts the wire
An electron beam heats the wire to melting. The computer-controlled beam position traces the part geometry, layer by layer.
Layer buildingLayer-by-layer construction
Molten metal from the wire flows onto the part. The beam traces the geometry, laying down a bead. The process repeats, stacking layers to form the final shape.
PrecisionClosed-loop control
Real-time sensors monitor melt-pool size, voltage and current. Software adjusts beam position and power to hold parameters constant across production runs.
