Title:
3D ADDITIVE MANUFACTURING DEVICE, CONTROL METHOD FOR 3D ADDITIVE MANUFACTURING DEVICE, AND CONTROL PROGRAM FOR 3D ADDITIVE MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163404
Kind Code:
A1
Abstract:
The present invention effectively suppresses the occurrence of scattered electrons such as secondary electrons and reflected electrons. This 3D additive manufacturing device is equipped with a linearly-shaped funnel for spreading a material for a 3D additively manufactured object upon a manufacturing surface whereon the 3D additively manufactured object is manufactured. The 3D additive manufacturing device is also equipped with an electron gun for generating an electron beam. The 3D additive manufacturing device is further equipped with a metallic deposition-preventing cover that is provided between the manufacturing surface and the electron gun. In addition, the 3D additive manufacturing device is equipped with a DC power source that applies a positive voltage to the deposition-preventing cover.
