Powder recycling is accepted as a key commercial advantage in Selective Laser Melting technology. Yet, surprisingly, little to no information is publicly available on this topic. So what’s the catch?
Selective laser melting (SLM) is used to manufacture a patient-specific stainless steel positioning guide for spinal screws. The screws are successfully inserted in the neck vertebrae of a 3-year old patient to strengthen unstable joints. This article highlights the challenges and describes the steps used to design, customise, build and post-process the component.
In Electron-beams systems, the back-scatter of electrons at the layer surface produces local electrical charge build-up and electrostatic ejection of particles from the powder bed: ’smoking’.
