“…Partial dentures have been prepared with a synergistic combination of FDM assisted CVS patterns and conventional dental casting [204]. Very recently, laser polishing was shown to improve the surface quality, mechanical and thermal properties of FDM aluminium/PLA composites [205]. These examples highlight the potential of post-processing techniques to improve one of the most important limitations of FDM, the poor surface quality or characteristic texture.…”

“…Laser polishing had shown significant improvement in the surface properties of FFF parts. [131][132][133] The key process variable that impacts the surface quality is laser power. The laser power and beam size of 3 W and 200 μm respectively are the optimal process conditions for the FFF PLA specimen.…”

The shift from rapid prototyping to rapid manufacturing using 3D printing is prominent after the development of volumetric 3D printing, multi-material printing, and functional materials development. Fused filament fabrication (FFF) is a fast-growing additive manufacturing technology with widespread end-user applications. The key constraints to its growth are the lower surface and mechanical properties compared to conventional manufacturing paradigms. The goal of this review is to look at the numerous pre-processing and post-processing parameters for the property enhancement of FFF. Preprocessing methods included optimization of process parameters (infill percentage, pattern, layer height, nozzle and platform temperature, raster angle and width, build orientation, and air gap) and adaptive slicing techniques.Mechanical (hot air jetting, barrel finishing, sand blasting, laser polishing, etc.), chemical (vapor smoothing, dipping, plating, and painting), and thermal (thermal annealing and normalizing) post-processing techniques were successful in improving the mechanical strength and surface finish of fused filament fabricated parts. This paper outlines the various methodologies a FFF user could incorporate for enhancing the final finished product's properties. The potential future prospects for the development of the 3D printing sector are also examined.

“…The deposited lines remelted due to the laser scanning speed, and the bond strength of the deposited lines improved. Thus, tensile strength increases first, then decreases as the laser scanning speed increases [125].…”

Polylactic acid (PLA) has increasingly attracted research in various industrial fields due to its great biocompatibility and sustainability over other thermoplastics, which are widely used as filament feedstock in 3D-printing technology, specifically in Fused Deposition Modelling (FDM). Despite PLA being suitable in FDM processing, it has limitations in applications that need plastic deformation at high-stress levels due to its low strength and ductility. For this purpose, this review article discusses the existing studies that involve the incorporation of fillers in 3D-printed polylactic acid to maximize its functionality, which is non-attainable by the pure filament material alone. An overview of polylactic acid in FDM and the properties and effects of functional fillers of different types are presented. Finally, a complete table of which functional fillers are categorized (carbonaceous, metallic, ceramic and glassy, plant-based, and mineral) summarizes the reported comparison of 3D-printed pure PLA and the composite, scoping to reveal the mechanical modifications of each filler.
