Arcam EBM Q20plus

The Arcam EBM Q20plus is an EBM 3D printer from GE Additive with a 350 x 350 x 380 mm build volume.

Calibration

• Verify vacuum integrity before any calibration run.

Action: Inspect the chamber seals, door interfaces, feedthroughs, and pump-down behavior; confirm the system reaches the documented vacuum regime of about 5 × 10^-4 mbar minimum chamber pressure and stabilizes near the typical build atmosphere of 4 × 10^-3 mbar partial pressure of helium before you attempt any beam calibration or production build.

Common defects

The provided sources do not document a formal recall, mandatory safety bulletin, or model-wide end-of-life notice for the Q20plus, but they do reveal several practical defect categories and operational risks that matter in production.

• Vacuum-system sensitivity and chamber-state instability

Symptoms: Slow pump-down, unstable pressure readings, build interruptions, or inconsistent part quality near the start of a build.

What it is used for

The Q20plus is best understood as an industrial metal production system for parts that benefit from EBM’s vacuum, high-temperature process window, and stress-relieved material behavior.

• Aerospace components are its clearest fit.
