“…This is because the manufacturing process produces less scrap compared to other processes, can use a wide range of polymer types, and some works have analyzed the reprocessing of these materials [6] , [7] , [8] , [9] . Moreover, this is a promising process to be widely used in the automotive, medical, and aerospace industries, and for the same reason, new materials have been emerging to suppress these requirements [10] , [11] . However, producing the filament requires an extruder, which is expensive and the industrial one has a considerable size.…”

“…To attach the corner (N) to the pieces of wood(Q), an M4 Phillips steel screw(J) is used on each, with an M4 steel gasket(L) and an M4 steel hex nut(M). It is important to note that this system does not use optical sensors that turn on or turn off the system, only using a preset speed, as used in other projects [10] . Another point is that the height of the piece of wood (Q) and the positioning of the M8 steel threaded rods bar (R) and the extruded profile 2020 (P), were defined using the diameter values of the filament rolls existing in the Brazilian market.…”

“…As 3D printing technology scales, understanding parameter-sensitive effects becomes essential for maintaining quality across larger production volumes, and this information aids in predictive modeling, simulation, regulatory compliance, education and training (Aydin and Kucuk, 2018; Jayasudha et al , 2022; Geng et al , 2023). Ultimately, these insights find practical application across industries like aerospace, automotive, health care, electronics and beyond, enhancing product performance, innovation and competitiveness (Peker et al , 2020; Hassanin et al , 2021; Hajare and Gajbhiye, 2022).…”

Purpose This paper aims to evaluate the mechanical behaviour of polycarbonate/acrylonitrile butadiene styrene (PC/ABS) filaments for fusion filament fabrication (FFF). PC/ABS have emerged as a promising material for FFF due to their excellent mechanical properties. However, the optimal processing conditions and the effect of the blending ratio on the mechanical properties of the resulting workpieces are still unclear. Design/methodology/approach A statistical factorial matrix was designed, including infill pattern, printing speed, nozzle size, layer height and printing temperature as factors (with three levels). A total of 810 workpieces were printed using PC/ABS blends filament with the FFF. The workpieces’ finishing and mass were evaluated. Tensile tests were performed. Analysis of variance was performed to determine the main effects of the processing conditions on the mechanical properties. Findings The results showed that the PC/ABS (70/30) exhibited higher tensile. Tensile rupture corresponded to 30% of the tensile strength. The infill pattern showed the highest contribution to the responses. The concentric pattern showed higher tensile strength. Tensile strength and mass ratio demonstrated the influence of mass on tensile strength. The influence of printing parameters on deformation depended on the blend proportions. Higher printing speed and lower layer height provided better quality workpieces. Originality/value This study has implications for the design and manufacturing of three-dimensional printed parts using PC/ABS filaments. An extensive experimental matrix was applied, aiming at a complete understanding of mechanical behavior, considering the main printing parameters and combinations not explored by literature.

“…There are also disadvantages to the use of AM, such as, e.g., a small range of available raw materials, restricted build size, postprocessing of the printed parts (cleaning and sanding, water jetting, a chemical soak and wash, air or heat drying, etc. ), possible design inaccuracies, and the potential to disrupt the industry and affect employment rates in the long term [3,5]. Nevertheless, AM is a very competitive technology compared to traditional manufacturing approaches such as compression and injection moulding, extrusion, etc., especially for the low-volume fabrication of small parts (e.g., aircraft interior spare parts).…”

Flame-Retardant and Tensile Properties of Polyamide 12 Processed by Selective Laser Sintering

et al. 2022

Composite materials are becoming widely applied in fire-critical conditions such as, e.g., aviation interior parts. Environmental considerations motivate the use of additive manufacturing due to the decrease of polymer wastes, and therefore additional fuel sources. The aim of this work was to evaluate the effect of printing direction on flame retardancy and the tensile properties of 3D-printed test samples of polyamide 12 manufactured by selective laser sintering. The effects of printing parameters on the flammability of 3D-printed samples were investigated using vertical burn tests with varied specimen thicknesses and printing directions. It was found that these effects were substantial for the flammability at a low thickness of the test samples. No significant effects of printing direction were revealed for the tensile characteristics of polyamide 12.
