Electron Beam Melting (EBM) and Selective Laser Melting (SLM
Why do Electron Beam Melting (EBM) and Selective Laser Melting (SLM) use such different preheating temperatures?

EBM operates in a vacuum with a fast-scanning electron beam, creating strong thermal gradients, so high preheating (~700 °C) is needed to reduce residual stresses. In contrast, SLM uses a laser with more localized heating, so lower preheating (~200 °C) is sufficient, mainly to limit moisture-related issues and build plate distortion.
