Wayland Additive will exhibit its original and highly effective metal additive manufacturing (AM) system, Calibur3 featuring the NeuBeam process, at Formnext 2021 in Frankfurt, Germany, November 16-19.

Following the launch of Calibur3 earlier this year, Formnext will be the first opportunity for a much broader audience to get to see Calibur3 in person and to get a deeper understanding of the benefits that Calibur3 offers, specifically with how the NeuBeam metal AM process facilitates this.

A Wayland Additive team will be available on stand B139 in Hall 12 to meet visitors, introduce them to Calibur3 — which will be on the show floor — and discuss any metal AM application requirements. Anyone planning their schedule ahead of the event can pre-book a meeting with a Wayland executive.

The NeuBeam process provides manufacturers with access to a genuine metal AM production alternative. This is because NeuBeam delivers on all of the advantages of metal eBeam powder bed fusion (PBF) technology, while overcoming the troublesome issues that have traditionally limited wider adoption. At Formnext, Wayland will be highlighting the three core principles of NeuBeam — stability, flexibility, and metallurgy.

The most fundamental issue with electron beam (eBeam) AM technology has always been the unstable nature of the processes and Wayland has categorically resolved this. The Wayland team comprises decades of experience with eBeam research, development and implementation in the semi-conductor industry. This has allowed them to address and solve the charging issues that have, until now, restricted EBM processes, with the fully neutralized NeuBeam process.

The other key feature of NeuBeam is that it is a hot part process rather than a hot powder bed process like traditional eBeam processes. Therefore, Calibur3 can efficiently produce parts that are free of residual stresses because the high temperatures are only applied to the part and not the whole powder bed, ensuring free-flowing powder post-build (no sinter cake) and stress-free parts with reduced energy consumption. This makes the process considerably more flexible in terms of part geometries, and cost-efficient because heat treatments and other post-processing steps are dramatically reduced.

Workarounds for traditional eBeam processes have been developed by the AM industry, but these lead to downstream complexities including time-consuming and expensive part removal and post processing. These compromises also severely limit the materials that can be used with traditional eBeam AM. Neubeam is material and can potentially run a much wider palette of metal materials, including refractory metals.
