ADDITIVE MANUFACTURING DEVICE UTILIZING EB-LASER COMPOSITE SCAN

Title:

ADDITIVE MANUFACTURING DEVICE UTILIZING EB-LASER COMPOSITE SCAN

Document Type and Number:

WIPO Patent Application WO/2016/141876

Kind Code:

A1

Abstract:

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 composite 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.
