SpletPred 1 dnevom · PBF can be used for rapid prototyping, visual prototyping, low volume production, or full high volume production runs PBF requires little to no support structures, reducing post-processing times The material choice across all PBF options is impressive and is one of a few methods which can create reliable metal parts SpletPowder bed fusion (PBF) methods use either a laser or electron beam to melt and fuse material powder together. Electron beam melting (EBM), methods require a vacuum but can be used with metals and alloys in the creation of functional parts. All PBF processes involve the spreading of the powder material over previous layers.
