nozzle clogging factors during fused filament fabrication
Fabrication of ABS/Graphene Oxide Composite Filament for
Additive manufacturing the so-called three-dimensional (3D) printing is a revolutionary emerging technology. Fused filament fabrication (FFF) is the most used 3D printing technology in which the melted filament is extruded through the nozzle and builds up layer by layer onto the build platform. The layers are then fused together and solidified into final parts.
