Additive manufacturing and acoustic Emission: a brief review

Abstract

Additive manufacturing (AM) or 3D printing (TDP) will be the next-generation manufacturing process replacing the traditional manufacturing process. A tiny toy to a rocket part is being manufactured by the AM. Depending on the condition of use, environment, installation, vibration, fatigue, and types of motion such as static or dynamic, material properties might change day by day. Special attention is necessary for selecting and monitoring these objects or parts for human safety. Consistent and scheduled monitoring of the 3D structure is required to show the future manufacturing process and avoid such casualties. As the demand to produce AM items has been increasing exponentially, monitoring the structural health must be taken into consideration for the safety of the users. Structural health monitoring (SHM) utilizes several non-destructive techniques and methods to detect and monitor the structure. Acoustic Emission (AE) is a great way to see the crack formation of the modern structural health monitoring (SHM) system. This study mainly focused on two topics, AM and AE. Considering AM, a brief 3D printing history and types have been discussed. Also, this study connects a novel kind of review AE and AM, as per the information from different search engines.
