Optimising the FDM additive manufacturing process to achieve maximum tensile strength: a state-of-the-art review (2019, result): “Various physical processes govern the formation of these bonds and are considered in detail by [42, 43, 44, 45], with [16] developing filament and macro scale FE models to consider the effect or raster angle and air gap in ABS printed parts and comparing results to a physical test campaign.”
Fatigue performance of fused filament fabrication PLA specimens (2018, background): “The semimelted material is deposited on the previously laid layer, so that both hot fibers of material are joint through a local sintering process of neck growth, as described in [3].”
