TADA EZ300

The TADA EZ300 is an EBM 3D printer from TADA Electric with a 250 x 250 x 300 mm build volume.

Specifications

TADA EZ300: Technical Profile

Electron Beam

6 kW self-calibrating EB beam. TADA Electric draws on Mitsubishi Electric Group's decades of electron beam welding heritage. Proprietary rod-shaped cathode with ≥ 1000-hour lifespan: longest in class at product launch.

Build Rate

250 cc/h claimed throughput: leading figure in the EBM class at launch.

Platform

Build volume 250 × 250 × 300 mm; standard layer thicknesses 50–150 µm.

Chamber / Protective Atmosphere

Vacuum chamber for clean metallurgy without oxidation; no helium purge required (standard EBM).

Calibration

TADA EZ300 Calibration

Automatic Self-Calibration

The EZ300 has a built-in self-calibration procedure for the EB beam (focus/astigmatism/position): no manual intervention required under normal operation. On alarm: contact TADA service.

Vacuum Readiness

Confirm operating pressure before activating the beam. Monitor pump-down time as an indicator of seal condition.

Powder Bed Preheat

Multiple defocused beam scans sinter the powder layer.

Common defects

Typical Defects on TADA EZ300

Smoke Event

Electrostatic powder dispersal at insufficient preheat. Risky for the focusing system. Fix: additional preheat cycles; dry powder.

Porosity

Gas-type (moisture) or LOF (parameter error). Check beam current and scan speed parameters; UT or CT inspection post-build.

Residual Stress / Distortion

From non-optimal scan strategy or low build temperature. Optimize island scanning; verify thermal profile.
