due to the lack of melting and blending pressure in the FDM device, the microstructure observed in the printed samples remains similar to the filament and is even exacerbated.
The porosity within the samples is reduced by printing them along the 90° direction according to the long axis, falling to values of 8.4 ± 1.7, 11.1 ± 3.1 and 14 ± 1.2% for printing widths of 100, 200 and 300%, respectively, when compared to the 0° printing direction.
