N2 - This paper proposed 3D printing of orthotropic material, carbon fiber-reinforced polymers, based on the optimized material orientation and distribution. First, the cross-ply orthotropic material orientation and distribution were optimized using the gradient-based anisotropic topology optimization method to maximize the structural stiffness. Then, the continuous 3D print path was generated from the optimized material orientation and distribution using the biological pattern-forming system. Finally, the optimized structure was 3D printed based on the 3D print path by means of the fused filament fabrication. The proposed structure brought the full potential of orthotropic materials minimizing the structural weight.
