This paper proposes a concept for the development of an in-process monitoring system to
assess the quality of components manufactured via the Material Extrusion (ME) Additive
Manufacturing (AM) process. The development of such a system has the potential to allow
component manufacturers to identify weaknesses within the structure of a built component
prior to distribution to customers and subsequent premature in-service failure. Following
proposal of the concept, this paper proceeds to highlight a number of key hardware and …

Additive Manufacturing (AM) techniques comparing to conventional manufacturing
techniques offer production of low-volume, highly customised, geometrically complex parts
[1]. In recent years, as a result of significant improvements in materials properties and
processes accuracy, AM processes are increasingly being utilised for the production of
highly complex and quality critical components within sectors such as the aerospace
industry [2, 3, 4]. Therefore inspecting the surface quality, dimensional accuracy, inter-and …
