3.5. Comparative study This result has been approved by a comparative study of the mechanical properties between the extruded filament and the mechanical properties of the raw material. Fig. 13 shows the different properties of each one of them. It’s should be noted that the properties of the real one (raw material) given by its datasheet in (https://www.campusplastics.com).
