Electron Beam Melting (EBM) is a Powder Bed Fusion (PBF) method that uses an electron beam to melt metallic powder. Powder Bed Fusion processes typically use support structures to stabilize overhanging surfaces, reducing thermal gradients during cooldown and minimizing the risk of warping. This thesis work aims to optimize partially-sintered volumetric supports structures, recyclable through the Powder Recovery System (PRS, a powder recovery station that allows the just-printed build to be cleaned of any residual loose powder), to support LPT Blades overhangs during manufacturing via Electron Beam Melting (EBM) process. This new type of support is intended to eventually replace the current production supports, which are fully melted (and therefore not recyclable back into powder), resulting in less material waste and shorter support-removal times.
