A SYSTEMATIC LITERATURE REVIEW ON APPLICATIONS OF THERMOPLASTIC MATRIX AND THERMOSETTING REINFORCED POLYMER COMPOSITES IN 3D PRINTING

Abstract

 This systematic literature review (SLR) examines the applications, properties, and processing of thermoplastic matrix and thermosetting reinforced polymer composites in 3D printing, providing insights into current advancements and future directions. The study investigates polymer matrix types, the role of reinforcements such as fibers, nanoparticles, and hybrid fillers, and the suitability of various additive manufacturing techniques, while identifying research gaps and industrial challenges. A rigorous SLR methodology was employed, searching peer-reviewed journals, conference proceedings, and databases including Scopus, Web of Science, ScienceDirect, SpringerLink, and IEEE Xplore, covering 2016–2025. Keywords such as “thermoplastic matrix composites,” “thermosetting reinforced polymers,” “3D printing,” “additive manufacturing,” and “nanocomposites” were used. Data extraction focused on polymer types, reinforcement characteristics, processing methods, mechanical and thermal performance, and applications. Findings show that thermoplastic composites (Polylactic Acid, Acrylonitrile Butadiene Styrene, Polyethylene Terephthalate Glycol-modified,Polyether Ether Ketone, Polyetherimide) are preferred for recyclability, processability, and design flexibility, while thermosetting composites offer superior mechanical strength, thermal stability, and chemical resistance. Reinforcements enhance tensile, flexural, and impact properties, with hybrid and functional composites enabling electrical conductivity, self-healing, and antibacterial properties. Advanced 3D printing methods (Fused Deposition Modeling, Fused Filament Fabrication, Stereolithography Apparatus, pellet extrusion) enable precise fiber alignment, layer control, and complex geometries, supporting aerospace, automotive, medical, and industrial applications. Challenges include interfacial bonding, anisotropy, thermal degradation, and limited standardization, highlighting the need for research on high-performance, multifunctional, and sustainable 3D-printed composites.
