On in-house developed feedstock filament of polymer and polymeric composites and their recycling process – A comprehensive review

Abstract

In the last few decades, tremendous effort is given to the production of various polymers and polymeric composites components through innovative polymer processing techniques. Fused deposition modeling (FDM) of polymers as a printing technique in additive manufacturing has been explored extensively due to its cost-effectiveness, manufacturing capabilities, flexibility in material selection, and dimensional accuracy. A few reviews of the literature have been done to investigate various applications for polymers, but none have focused on the research on commercial and in-house generated polymers and polymeric composites, particularly those made using the FDM printing technology. Consequently, the study data on the internal development of polymer and polymeric composite filament-based FDM printing is gathered and processed in this work. The work also highlights various types of polymeric composites and recycled polymeric composites with their detailed material characteristics. In addition, various applications of FDM printing of polymeric composites at the industrial scale and domestic level usage are highlighted as the potential to reduce carbon emission through the effective recycling process.
