Additive manufacturing (AM) has several advantages that will make a revolution in polymeric material development. In the AM of polymeric materials, filament deposition modeling (FDM) has been widely used owing to its versatility, low cost, and efficacy. FDM includes different parameters and also an interlayer adhesion that contributes to the performance of the printed parts. In recent years, reinforcement has been introduced in FDM‐printed polymeric materials to improve performance. This review looked at different polymer materials that were printed using the FDM process. A systematic literature search was conducted on FDM‐printed polymers, and the mechanical and thermal performance of these materials was reviewed and critically reported. The performance of FDM printed polymeric materials has been discussed in relation to FDM process parameters, matrix type, fiber reinforcement type, particle reinforcement type, and lattice structure. In a nutshell, this review article will assist researchers working in the field of 3D printing of polymeric materials in understanding the various polymer and polymeric composites' properties and performance.

Additive manufacturing technology has found its development in the various emerging engineering fields. Fused Deposition Modeling (FDM) had proven to be a suitable built-up technique for any complicated and instant shapes. Owing to the advantage of additive manufacturing and emerging industrial needs, the 3D composite filament has been used as a competitive material over the available materials. Commercially available Poly Lactic Acid (PLA), ABS filaments have been widely used in FDM. In the present work, copper particles of mesh size mesh 20-30 micrometers are taken as the reinforcement in the PLA matrix. After primary investigation, 12% of copper particles are found to be a suitable weight percentage in the PLA matrix. The suitable proportional mixture is ball milled for 2 hours, melted to 120oC, and then hot extruded to get a filament diameter of 1 mm. The newly fabricated 3D composite filament is printed at different FDM conditions for the compression test to the ASTM D695-15 standard. The printed samples are subjected to a compression test until failure. Failure mechanism happened on different condition printed samples are examined through scanning electron microscope (SEM) examination. The compression effect causes the squeezing and slippery action of copper particles inside the structure leads to having a displacement of particles.
