It can be seen that the short carbon fibers lie within the filament in a plane orthogonal to the applied load. Thus, as they are not aligned with the load direction, fibers do not significantly contribute to the sample’s load-bearing capability. Figure 5. Comparison between the mechanical ...
used for the production of filament, and for most samples, the FDM printing process can be conducted without any difficulties. Unfortunately, the unmodified blends are characterized by brittleness, which makes it necessary to use an elastomer additive (IM). The presence of a semicrystalline PET ...
In fact, this parameter influences the fluidity of the extruded filament, its solidification characteristics and the consequent inter-bonding strength between the solidified layers [36]. According to Ding et al. [38], the density of the extruded materials increases gradually with temperature, which ...
