**Abstract**

The recent techniques for improving polymer-based composite properties using nanoclay infusion have been reviewed in this chapter. The recent progress in the printing of thermoplastic composite infused with different sizes of particles was reviewed. The processing of infusing clay into natural fiber and recent advancements in the printing of thermoplastic composite infused with nanoclays at different loading ratios also was discussed. Valid information on different apparatuses for determining mechanical properties, temperature dependence storage modulus, and tan α of the developed materials were provided. The loading effect of clay on the mechanical properties, temperature dependence storage modulus, and tan α of composite and nanocomposites was reviewed. Specific emphasis on printed nanocomposite application in gears and related engineering fields is considered. The innovative scope of infusing nanoclay for developing composite with improved mechanical properties, temperature dependence storage modulus, and tan α was discussed. Similarly, the application of clay-reinforced composite with the revolutionary scope of infusing nanoclay for different applications was suggested.
