GE Additive today unveiled the Arcam EBM SpectraTM L at Formnext 2019, Frankfurt Germany. The Spectra  L is reported to meet increased demand for higher productivity, especially from the aerospace industry, and offers customers a larger build volume and 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.

GE stated that 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 the systems offering almost double the build volume of the Arcam EBM Spectra H, and being 13% larger than the Arcam EBM Q20plus.

The Spectra L has largest build envelope (Ø350x430mm) in the Arcam EBM solution portfolio and features 4.5 kW beam power which increases build speed by 20%, compared to the Arcam EBM Q20plus. System improvements to powder layering and heat model control result in the Spectra L completing a full height build some 4.5 hours faster than the Arcam EBM Q20plus.

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

“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.
