    • An additive manufacturing device comprises: a vacuum forming chamber (1), a worktable device, a powder supply device, at least one electron beam (EB) emission focusing and scanning device (6), at least one laser beam emission focusing and scanning device (7), and a controller. A forming region of the worktable device is at least provided within the vacuum forming chamber (1). The powder supply device is configured to supply powders to the forming region. Scanning ranges of the EB emission focusing and scanning device (6) and the laser beam emission focusing and scanning device (7) are configured to cover at least a part of the forming region. The controller is configured to control the EB emission focusing and scanning device (6) and the laser beam emission focusing and scanning device (7) so as to perform a powder scanning and forming integrated treatment on the forming region. The additive manufacturing device can apply additive manufacturing to create three-dimensional parts having a good-performance, high-efficiency, and high-precision, and highly adaptive to different materials.
    • 一种增材制造装置包括:真空形成室(1),工作台装置,粉末供应装置,至少一个电子束(EB)发射聚焦和扫描装置(6),至少一个激光束发射聚焦和扫描装置 (7)和一个控制器。 工作台装置的成形区域至少设置在真空成形室(1)内。 粉末供应装置构造成将粉末供应到成型区域。 EB发射聚焦和扫描装置(6)和激光束发射聚焦和扫描装置(7)的扫描范围构造为覆盖成形区域的至少一部分。 控制器用于控制EB发射聚焦扫描装置(6)和激光束发射聚焦扫描装置(7),对成形区域进行粉末扫描并形成一体化处理。 增材制造装置可以应用增材制造来创建具有良好性能,高效率和高精度,并且对不同材料具有高度适应性的三维部件。
