Abstract
An additive manufacturing device utilizing an electron beam and laser integrated scanning comprises: a vacuum generating chamber (1); a worktable means having a forming region at least provided in the vacuum generating chamber (1); a powder supply means configured to supply a powder to the forming region; an electron-beam emission focusing and scanning means (6) and an laser-beam emission focusing and scanning means (7) configured in such a manner that a scanning range of the electron-beam emission focusing and scanning means (6) and a scanning range of the laser-beam emission focusing and scanning means (7) cover at least a part of the forming region; and a controller configured to control the electron-beam emission focusing and scanning means (6) and the laser-beam emission focusing and scanning means (7) to perform a powder integrated-scanning and forming treatment on the forming region.
