How much does the GE Additive Arcam A2XX cost?
Estimated price range
Our best estimate for a metal additive manufacturing in this class — not a quote from Colibrium Additive. Configuration moves it a long way.
Overview
The GE Additive Arcam A2XX is an Electron Beam Melting (EBM) machine with a listed build volume of 200 x 200 x 380 mm and 3,000 W of electron beam power. It is not in Colibrium Additive's current lineup. The description below is drawn from the listed figures alone, and nobody has been able to check them against a maker's page, so ask for the original documentation of any machine under consideration.
The build volume is tall for its plan area, with 380 mm of height over a 200 x 200 mm base. That shape favours long parts stood upright or several tiers of smaller parts. On the listed figures this is a coarse, hot process: layer thickness is 50 – 200 µm, the beam focus diameter is variable from 0.2 – 1.0 mm, and build temperature is given as up to 1000°C depending on the alloy. As-built surface roughness is listed at Ra 25–35 µm, so mating faces, bores and sealing surfaces need machining stock left on them.
Compatible materials are Ti-6Al-4V, Ti-6Al-4V ELI, CoCrMo and Titanium CP. The vacuum level is listed at < 1 × 10⁻³ mbar and scanning speed at up to 8,000 m/s for the electron beam. For installation, the listed figures give a footprint of ~2.0 x 0.9 m and a power requirement of 32 kVA. Machine weight and helium consumption are not listed.

Strengths & Limitations
Strengths
- 380 mm of build height over a 200 x 200 mm base, in a listed build volume of 200 x 200 x 380 mm
- 3,000 W of electron beam power with a variable beam focus diameter of 0.2 – 1.0 mm
- Build temperature listed at up to 1000°C (alloy dependent)
- Listed footprint of ~2.0 x 0.9 m
Limitations
- Not in Colibrium Additive's current lineup, and the listed figures are unconfirmed
- As-built surface roughness of Ra 25–35 µm means functional surfaces need finish machining
- Only four compatible materials are listed: Ti-6Al-4V, Ti-6Al-4V ELI, CoCrMo and Titanium CP
- Layer thickness starts at 50 µm, which limits fine detail

Frequently Asked Questions
01
No. The A2XX is not in Colibrium Additive's current lineup, so it is best treated as an older model. The figures on this page are the listed figures and have not been confirmed against a maker's page; verify them from the documentation of the machine itself.
02
The listed build volume is 200 x 200 x 380 mm, so the height of 380 mm is nearly twice the 200 mm side of the base. Layer thickness is listed at 50 – 200 µm and the beam focus diameter at 0.2 – 1.0 mm (variable).
03
Ti-6Al-4V, Ti-6Al-4V ELI, CoCrMo and Titanium CP. Build temperature is listed as up to 1000°C, alloy dependent, and the process runs at a listed vacuum level of < 1 × 10⁻³ mbar.
04
As-built surface roughness is listed at Ra 25–35 µm. That is a rough surface by machining standards, so leave stock on faces that locate, seal or carry a bearing and plan a finishing operation after the build.
