UK-based engineering agency Wayland Additive has introduced the event of its new electron beam powder mattress fusion expertise – NeuBeam. After licensing the method from mother or father firm Reliance Precision, Wayland hopes to commercialize it and fulfil six deliveries of the system by the tip of the yr.
Cost impartial 3D printing
In response to Will Richardson, CEO of Wayland Additive, NeuBeam is able to neutralizing the cost accumulation that tends to happen with different electron beam applied sciences akin to electron beam melting (EBM). This leads to a wider vary of viable print parameters and elevated materials flexibility with NeuBeam, when in comparison with different electron beam or laser-based PBF applied sciences.
Dubbed by the CEO as a “sizzling half course of” versus a “sizzling mattress course of”, the NeuBeam system will see warmth being utilized to solely the related sections of the construct space, the place the half is being printed. This has the impact of avoiding partially sintered powder, which may fuse to the half, deteriorating its floor end. Unused free flowing powder is left within the mattress, and any powder in or on the half might be eliminated with minimal post-processing.

The problem of residual stress has been round for so long as PBF, and might be harmful in excessive circumstances. The speedy cyclic heating and cooling attributable to the hatching, or scanning, of the beam leads to layer contraction. The assorted layers pull on one another and kind shear stresses inside the half. The impact is most extreme in components with massive cross-sections, as these are inclined to have longer weld-tracks so there’s a larger distance for the shear stresses to behave over. If the NeuBeam actually can fabricate stress-free components, it might doubtlessly allow massive half manufacturing on a scale presently unseen in PBF.
Actual-time in-situ monitoring
Wayland’s NeuBeam system additionally options real-time in-situ half monitoring through structured mild scanning, electron imaging, and excessive velocity infra-red digicam modules. This provides customers the choice to alter course of parameters mid-print to optimize the half’s microstructure as it’s being shaped or to utterly cancel a print whether it is past restore. Wayland additionally expects the monitoring and fine-tuning enabled by the monitoring system to assist researchers in materials growth.

With its NeuBeam system, Wayland is seeking to shake up the electron beam PBF market. Utilizing £3M in funding, an funding led by Longwall Ventures and the Angel CoFund, the Yorkshire-based firm hopes its multitude of options can be sufficient to topple a few of the extra established EB system producers. Simply final yr, Ruselectronics, a Russian holding company and subsidiary of state-owned Rostec, introduced the event of its personal EBM 3D printer for aerospace functions.
