This review investigates and analyses the effects and usage of solid lubricants on high melting polymer printed via fused filament fabrication (FFF). The analysis indicated that most FFF printed parts suffer non-uniformity in mechanical properties, and such printed pieces are generally weaker thanconventionally produced counterparts. About 95% of research on FFF was about solving the weakness and non-uniformity of mechanical properties, with 98% ignoring the tribological effects. Addition of laminar solids to polymer improves not only the tribological properties but also some mechanical properties. Nevertheless, the effects of laminar solid results on polymer might not be predictable as the outcome depends on relative properties of such polymer, solids and FFF processing parameter. It is suggested that further research should be carried out on the effects of laminar solids on FFF processed polymer. |
