description	3D Printing technology is being widely used in the manufacturing industry and academic purpose research. This results in a significant increase in polymer consumption as the usage of 3D printer filament increases. The idea of using a filament extruder enables the reuse of the 3D printed objects made of ABS and PLA and turns them back into 3D printer filament.
