NeuBeam Electron Beam PBF

Electron beam additive manufacturing was developed as a process over 20 years ago, along with its competing technology, selective laser melting. Both have advanced and developed significantly in that time. Wayland Additive is a relatively new entrant to the metal additive market, offering a 3rd way with a new technology ‘NeuBeam’ that has electron beam melting at its core. At the heart of NeuBeam is a process that mitigates against excessive electron charge accumulation on the surface of the metal powder particles. In a standard electron beam PBF process, excessive charge accumulation will initiate build limiting ‘smoke events’ as a result of repulsive electrostatic forces between adjacent powder particles. A traditional E-PBF process overcomes the smoke issue by employing a wide-area sinter to fuse the powder layer into a mechanically stable conductive layer before melting. In the NeuBeam E-PBF process stability is maintained without the requirement to wide-area sinter. Wayland Additive will outline the NeuBeam AM process and the Calibur3 AM system, detailing the advantages of NeuBeam relative to standard E-PBF AM.
