A review of extrusion-based additive manufacturing of multi-materials-based polymeric laminated structures

Additive Manufacturing (AM) techniques have garnered significant attention for their applicability in fabricating intricate and complex geometries, end-user products, expediting prototyping processes, creating functional devices, sensors, and metamaterial structures for various applications. A relatively nascent area of exploration within this realm is using Extrusion-based Additive Manufacturing (EbAM) to produce multi-materials-based laminated, clad, or panel-based polymer composite structures. This study delves into recent advancements in clad, laminated, or panel-based polymer composite fabrication through EbAM, offering a comprehensive review of relevant literature. The examination encompasses a brief literature review, exploring potential applications for the fabricated composites, scrutinizing 3-dimensional printing (3DP) conditions, identifying optimum 3DP parameters, and assessing the resultant mechanical and functional properties. Furthermore, the article addresses the drawbacks and deficiencies found in existing studies, highlighting areas requiring attention in future research endeavours. A culmination of the review involves discussing the identified future research gaps in the fabrication of laminated composites via EbAM. By synthesizing insights from recent works and elucidating accomplishments and limitations, this article contributes to the collective understanding of the evolving landscape of EbAM techniques for multi-materials-based polymer laminated composite structure (LCS) and lattice structures fabrication.
