A review on composite materials and process parameters optimisation for the fused deposition modelling process (2017, background): “…Boparai et al. 2016a), extrusion velocity, filler particle size, raster orientation (Es-Said et al. 2000, Lee and Huang 2013, Hill and Haghi 2014, Garg et al. 2016), filling velocity (Ning et al. 2016), raster angle (Chockalingam et al. 2016), road width (Anitha et al. 2001, Duigou et al. 2016)…”
Effect of chemical treatment on tensile strength and surface roughness of 3D-printed ABS using the FDM process (2018, background): “Cold vapours change the surface to a semisolid state due to the deterioration of the secondary bonds, and the slight flow of thermoplastic layers fills the gap between the nearby layers and helps in enhancing the surface quality after the cold vapour treatment (Garg et al. 2016, 2017).”
Overview on Additive Manufacturing Technologies (2017, background): “Unconventional finishing processes might also be employed to improve the superficial finishing [26-28].”
