    Thermoplastic Elastomers (TPEs) are a new generation of engineering polymers with many applications, but their use in the emerging 3D printing technology remains incomplete. Inadequate strength and printing problems (buckling during the transfer of the filament into the thermal chamber and nozzle) are the main obstacles. In this paper, an attempt has been made to address these challenges simultaneously by using polymer blending and changing the printing mechanism. Polyethylene (PE), polypropylene (PP), and acrylonitrile butadiene styrene (ABS) were used to enhance the mechanical properties of Polyolefin elastomer (POE), and the granule-based FDM method, in which granule is the input material, was used for printing POE-blends. Additionally, morphology, printability, and dynamic thermomechanical analysis were examined. Scanning electron microscopy (SEM) images and Dynamic mechanical thermal analysis demonstrated that PE and PP have a single-phase composition, POE-ABS morphology indicated immiscibility (two phase morphology). The results of the mechanical properties via tensile test showed an increase in strength when each of these thermoplastics is blended with POE, which can be justified due to the higher strength of these materials compared to pure POE. The highest tensile strength of 10.91 MPa and 3166% elongation were obtained for POE-PE. This diversity in morphology and mechanical properties is one of the goals of this research which is well fulfilled, and these materials can be added to the library of 3D printing materials for industrial applications.

    The concern for plastics pollution, awareness of sustainability, and necessities of high-performance materials for modern industries have stimulated the world towards the advancement of natural fiber-reinforced polymeric composites. The review aimed to explore the tribological behaviour of natural fiber-reinforced polymeric composites and identify the characteristics of natural fiber-based polymeric composites. The different manufacturing techniques, tribological characteristics and applications of natural fiber-reinforced polymeric composites are outlined. Moreover, the review critically summarized the impact of fiber characteristics and treatments on the performance of natural fiber-reinforced polymeric composites. The advances and approaches to enhance the performances of the natural fiber-reinforced polymeric composites are summarized. The work presented the recent progress allied with several aspects of natural fiber-reinforced polymeric composites. The discussions for the life cycle assessments and degradation of the natural fiber-reinforced polymeric composites are provided. The treatment of the fibers with suitable reagents removes the wax, lignin, cellulose, impurities, etc., thereby enhances the compatibility between the reinforcement and matrix. Moreover, the reinforcement of fibers in polymers improves the strength and wear resistance of the composites. The life cycle assessments have reported that natural fiber-based polymeric composites have a lower environmental impact in comparison to conventional composites. The review has explored the prospects of sustainable natural fiber-based polymeric composites for tribological applications includes; floor tiles, instrumental panels of automobiles, house elements, car bumpers, doors and window panels, etc. This review has provided several vital information on advanced natural fiber-based composites for their prospective tribological conditions. The review is beneficial for the promotion of sustainability in modern industries and is advantageous for techno-eco and environmental points of view. The review will assist the researcher in working for the advancement of composites and practitioners involved in the domain of sustainability and environmental issues.
