GE Additive unveils Arcam EBM Spectra L

GE Additive today unveiled the Arcam EBM Spectra™ L at formnext. The Spectra L meets increased demand, especially from the aerospace industry for higher productivity and offers customers a larger build volume, faster speed, married with an integrated system architecture, new machine health analytics and automation features.

The latest addition to the Arcam EBM Spectra family will be manufactured at the GE Additive Arcam EBM facility in Gothenburg, Sweden and is available for order now, with delivery expected at the end of Q1 2020. Spectra L supports grade 5 Ti6Al4V, grade 23 Ti6Al4V and is well-suited for large titanium applications that cannot be achieved with laser. Support for pure copper is planned for 2020.

Reduced cost through increased productivity

The Spectra L has been developed to reduce cost by increasing productivity. Gains in build volume and build speed reduce cost per part by 10% thanks to:

  • Almost double the build volume of the Arcam EBM Spectra H, and 13% larger than the Arcam EBM Q20plus, the Spectra L has largest build envelope (Ø350x430mm) in the Arcam EBM solution portfolio
  • The Spectra L features 4.5 kW beam power which increases build speed by 20%, compared to the Arcam EBM Q20plus. And with system improvements to powder layering and heat model control improvements, the Spectra L completes a full height build 4.5 hours faster than the Arcam EBM Q20plus.

Improved part quality and material properties

The Spectra L provides a more consistent and accurate beam with improved auto beam calibration. This results in more consistent material properties for thin and bulky geometries.

Integrated System Architecture

The Spectra L builds on the extensive end-to-end industrialization features debuted on the Spectra H by enhancing and improving power handling, beam diagnostics and calibration, as well as automation.

  • The Spectra L is compatible with the Arcam EBM PRS 30, a new automated powder retrieval system – also launched at formnext – that is ideally suited to serial additive production environments and provides safe, efficient powder handling for operators.
  • A standardized Internet of Things (IoT) interface, built on an OPC Unified Architecture, helps customers connecting multiple machines together to facilitate data analytics.
  • Advanced data analytics are incorporated into the Spectra L. By combining data selected from sensors in the machine with intelligent algorithms, process and machine health analysis can be carried out, as well as reporting, root cause analysis and recommendations for corrective actions.

“The Spectra L is perfectly suited to those customers on the brink of, or those who have already begun to industrialize additive into their business,” said Karl Lindblom, general manager, GE Additive Arcam EBM.

“When we were developing the system feedback in particular from our aerospace industry customers centered on reliability, repeatability and automation, but increasingly – as they begin to scale their fleets of additive machines – also the need for process and machine health analytics and an integrated system architecture,” he added.
