摘要
This invention effectively suppresses the generation of scattered electrons such as secondary electrons and backscattered electrons. A three-dimensional laminating and shaping apparatus includes a linear funnel that recoats a material of a three-dimensional laminated and shaped object onto a shaping surface on which the three-dimensional laminated and shaped object is to be shaped. The three-dimensional laminating and shaping apparatus also includes an electron gun that generates an electron beam. The three-dimensional laminating and shaping apparatus further includes an anti-deposition cover made of a metal and formed between the shaping surface and the electron gun. In addition, the three-dimensional laminating and shaping apparatus includes a DC power supply that applies a positive voltage to the anti-deposition cover.
