The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Fatigue performance of fused filament fabrication PLA specimens (2018, background): “It also has a remarkable influence on surface roughness and unitary cost of a part, as the addition of more layers implies a higher material consumption for a fixed defined volume [22-23].”
Fused Deposition Modelling of Fibre Reinforced Polymer Composites: A Parametric Review (2021, background): “Durgan and Ertan [46] found that the “on-edge” ABS samples showed higher strength than the “flat” samples.”
A Systematic Survey of FDM Process Parameter Optimization and Their Influence on Part Characteristics (2019, background): “[4] investigated build orientation and raster orientation to determine the levels of both parameters that maximized the flexural strength of ABS parts.”
Investigating the influence of infill percentage on the mechanical properties of fused deposition modelled ABS parts (2016, background): “…there are several studies that contribute to the knowledge of their mechanical properties (Torres 2015; Lužanin 2014; Montero 2001; Ahn 2002; Lee 2007; Bellini & Güçeri, 2003; Durgun & Ertan, 2014), there are still uncertainties regarding certain other parameters, which can be obstacles for users.”
