造形後の造形物の表面の凹凸の例を図9、10、11に示す。図は造形物表面の断面の模様である。横方向は表面に平行方向で縦方向がそこでの凹凸の様子になる。図9は積層造形時の中央ビーム軸25に平行な面、図10は中央ビーム軸25に直交する面、図11は電子ビーム照射側に対して裏側の面である。それぞれの表面粗さは、Raは
積層造形工程の中央ビーム軸25に平行な面 29μm
積層造形工程の中央ビーム軸25に直交する面 9μm
積層造形工程の電子ビーム照射側に対して裏面 27μm
程度であった。このように、積層造形時の中央ビーム軸25に平行な面において、積層方向にそって連続した凸、あるいは連続した凹が発生することが多い。
Examples of irregularities on the surface of the modeled object after modeling are shown in FIGS. The figure shows a cross-sectional pattern on the surface of the model. The horizontal direction is parallel to the surface and the vertical direction is uneven. 9 is a surface parallel to the central beam axis 25 during additive manufacturing, FIG. 10 is a surface orthogonal to the central beam axis 25, and FIG. 11 is a surface on the back side with respect to the electron beam irradiation side. Each surface roughness Ra is 29 μm parallel to the central beam axis 25 in the additive manufacturing process
9 μm perpendicular to the central beam axis 25 in the additive manufacturing process
Back side 27μm for electron beam irradiation side of additive manufacturing process
It was about. As described above, a continuous protrusion or a continuous recess is often generated along the stacking direction on a surface parallel to the central beam axis 25 at the time of additive manufacturing.
