Inline process monitoring method for geometrical characteristics in additive manufacturing

Abstract This method provides a suitable solution for monitoring an additive manufacturing process. The implementation is evaluated in a manufacturing machine of fused filament fabrication. The main parts of the work are the developing and integration of an adaptable 3D hardware platform, the pre-processing of captured layer point clouds and the developing of object point cloud stack. The result is sufficient to estimate the manufacture quality and complies requirements for an inline process control method.
