3Dプリンター製ラチス構造材の引張強度特性

抄録

The lattice structure has possibility for making weight lighter. This is applicable for jet engine also. By utilizing 3D-printer, anyone can make lattice easier and cheaper. This paper report that tension tests are conducted with lattice specimen made by 3D-printer with orthogonal pattern. It is already known that those specimens have large surface roughness, therefore this paper shows the comparison between FEM result and tension test result to investigate this problem, and describe some notice for estimation of roughness.
