“…Primarily, the main challenge with all AM procedures is the reliability and repeatability of parts [8,9]. Due to the thermal cycles that are experienced by the part during the build process, residual stresses are induced, resulting in part distortions.…”

“…Another anticipated challenge in the use of AM to directly fabricate PPE through shared digital designs is the inherent variability between AM machines, materials, and build parameters [ 21 ], which can affect the mechanical properties of the printed materials and the accuracy of the printed geometries. In FFF, processing parameters such as layer thickness [ 12 ], layer orientation [ 22 ], raster width and spacing [ 23 ], and filament feed rate [ 14 ] influence porosity, part quality, and performance.…”

“…At present, main limitations for such use of the AM are the lack of robust and mature inspection, quality control and quality assurance techniques and an incomplete knowledge of the relationships between process, part shape, microstructure, and properties, which makes extremely difficult to anticipate the resulting material resistance to different failure modes, such as fracture, impact, creep, and multiaxial fatigue 1 . These limitations currently reflect in an extremely long and costly certification process for parts acceptability 2 . In order to develop reliable criteria for structural integrity assessment of AM parts, the role of process‐induced defects must be understood.…”
