A fundamental study of 3D printing testing methods for the development of new quality management strategies

摘要

A leading area of research in Additive Manufacturing, studies the quality of 3D prints using several testing strategies. This paper reviews two testing technologies: tensile testing (mechanical testing) and Scanning Electron Microscopy (SEM). The aim of this experiment was to provide a comparative study to better understand quality management processes in the 3D printing space. Additionally, this research study was performed to establish a good fundamental groundwork on which future Non-Destructive Testing research can be conducted. The study revealed the advantages of the tensile and SEM testing methods, whilst highlighting a need for better technologies to cover the disadvantages.
