“…They also attributed the lower performance of the wood-PLA filament to the defects such as a high porosity and lack of compactness. Kananathan et al [ 19 ] conducted a more focused study on wood-PLA composites by considering the role of the printing parameters. The authors showed that the infill rate and pattern significantly affected the mechanical properties under tensile, flexural, and compression testing conditions.…”

This study was aimed at considering the potential of wood-based composites processed using additive manufacturing as insulators in the building sector. A polylactic acid blend with 30% wood particles was used as a feedstock material in fused filament technology. Its thermal and mechanical properties were determined for various processing conditions, including printing temperature and infill rate. The results showed a minor contraction in its tensile performance as a result of the printing process. The printing temperature had a negligible effect on its stiffness and a limited influence on the other engineering constants, such as the tensile strength and ultimate stress. The thermal properties of printed structures have been found to significantly depend on the infill rate. Although the tested 3D printed wood-PLA material exhibited good thermal properties, which were tuneable using the printing conditions, its performance was still 38% to 57% lower compared to insulators such as the glass wool of the synthetic foams used in the building sector.

“…The nozzle distance should be uniform across the hot table. It is also important to make sure that the lament is extruded smoothly during printing without any irregularities or leakage on the printed table [43]. For reducing the effect of factors not directly related to manufacture, it is essential to clean the printer nozzle after each 10 printed specimens as a result of deterioration of geometrical printing accuracy [44].…”

3D printing techniques are becoming more common within several industrial fields due to their many benefits. These benefits include customized properties of final products, design independence, demand-driven manufacturing, waste alleviation, and the ability to produce complex parts, as well as fast prototyping. Parts manufactured using the powder bed fusion or material extrusion process are achievable by various building parameters. In this investigation, a comprehensive study was undertaken to clarify the variation in the compressive and impact strength of SLS prepared Nylon Polyamide and FDM prepared Nylon/CF parts at different building parameters. Significant methodological parameters were studied: infill patterns/layer layouts (triangular and rectilinear), wall thickness (1.2, 3.6, 6) and infilled density (70, 85 and 100%), utilizing material extrusion and powder bed fusion 3D printing machines. The Central Composite Face-centered (CCF)method was applied to design an optimal number of experiments. Experimental results demonstrated that Nylon Polyamide and Nylon/CF samples present slightly different crashing patterns and mechanical behaviors when tested for compression and impact. Compression characteristics of all tested samples are a progressive folding and lateral shearing failures amalgamation. Rectilinear samples are mechanically weaker than Triangle samples.

“…It is used in a wide range of applications, from rapid prototyping [9] and custom part production [10] to active materials [11], enabling complex designs to be processed with precision and efficiency [12]. The simplicity and adaptability of FFF have contributed to its prominence in the field of additive manufacturing, allowing a large spectrum of materials to be considered as feedstock materials from monophasic materials such as copolyester [13], polyurethane [14], and acrylonitrile styrene acrylate (ASA) [15] to composite materials such as PLA-flax [16], PLA-hemp [17], and PLA-wood [18].…”

This study aims to relate the microstructural arrangement, in particular the symmetry materialized by filament sequencing in the fused filament fabrication process, to the mechanical behavior of printed polyamide. Dog-bone structures were printed using various printing temperatures ranging from 250 °C to 280 °C, which were combined with part orientation including vertical, horizontal, and lateral configurations and raster angles (0°, 15°, 30°, and 45°) that represent the in-plane and out-of-plane symmetrical arrangement of the filament. Mechanical testing was conducted on both as-received filaments and printed structures to derive the effects of filament arrangement symmetry and process-generated defects on mechanical loss. In addition, a microstructural analysis using scanning electron microscopy was used to share more light on the filament arrangements and their consequence on the deformation mechanisms with respect to the printing conditions. The results showed that the 3D printed polyamide-based materials exhibited remarkable tensile performance with strain stiffening behavior and large elongation at break due to their particular filament layout. Among the considered printing conditions, the part orientation was found to have the largest influence on the tensile behavior, which modulates the behavior from complete restoration of the filament performance to mechanical loss.
