Current obstacles

Vacuum pump costUltra-high vacuum needs expensive pumps and maintenance, raising operating costs.
Speed tradeoffEBM melts slower than lasers; lower throughput. Offset by lower defect rates.

Physics limits

Vacuum chambers10-5 mbar vacuum across large envelopes is costly and needs skilled maintenance.
Beam stabilityBeams scatter in plasma if vacuum slips. Must stay ultra-low or focus drops.

How it works

3 parts

Electron Beam

Vacuum melting

Filament emits electrons, accelerated into focused beam. Strikes powder with high efficiency.

Low Stress

Vacuum environment

Vacuum prevents oxidation and slows cooling, reducing residual stress vs air.

Reactive Materials

Titanium safe

No oxygen/nitrogen in vacuum. Reactive alloys safe. Laser in air risks brittleness.
