C40-NbSi 2 with a hexagonal unit cell is focused as a high-temperature structural material. We first at- tempted the fabrication of the bulk C40-NbSi 2 products via selective laser melting (SLM) in additive manufacturing (AM) process. Strong crystallographic texture control wherein < 0 0 01 > was parallel to the building direction, i.e. development of the so-called basal fiber texture, was achieved in this study. The texture developed in products does not largely vary by changing the scanning strategy, unlike the tex- tures of C11 b -MoSi2 with a tetragonal unit cell and a β-Ti alloy with a cubic unit cell. A comparison of these results led us to the conclusion that crystal symmetry, i.e., the multiplicity of the preferential crys- tal growth direction, is one of the primary factors that governs the features of the textures developed in AM-built materials.
