| Abstract Scope |
The exploration of novel acoustic liner designs using 3D internal lattices has become a growing topic of interest within the field of additive manufacturing (AM). However, the comparison between the acoustic liner response of computational simulation and experimental testing tends to show significant deviation. A potential cause of this deviation is the inclusion of stochastic manufacturing defects within the part. This paper establishes a pipeline for identifying manufacturing defects in the prints of acoustic liners. The core of the liner design analyzed in this paper is made up of a Schwarz P lattice. Error distributions of several design variables are found by taking manual measurements of printed liners. Additionally, liners are scored using an automated screening method to detect significantly flawed prints. The potential for error distributions to be used in stochastic simulation studies could help predict what effect manufacturing defects have on the behavior of acoustic liners. |
