          and the quality of parts manufactured with recy-          friendly filaments by incorporating recycled
          cled materials vs. conventional materials. Some           materials.
          studies propose Chemical Recycling through py-
          rolysis as an alternative method to convert plas-     Filamentive production of recycled filament us-
          tic wastes to raw materials for 3D printing.
