“…[44] The authors recently showed the tensile properties of ABS, PLA, and PLA þ CF specimens (with percent infill) following a specific pattern (Triangular and Tri-Hexagon) of infilled material in gauge length. [45,46] The noteworthy contributions from the past work as mentioned above, illustrate the significant effect of printing parameters like orientations, layer thickness, bed and printing temperature, and cooling effect on the mechanical properties of materials. The various findings also suggest, the wide use of PLA materials in the field of biomedical for fabricating tissues and other sensitive body parts.…”

In view of reducing development and production costs of components in the fields such as automobile, aviation, sports, and biomedical, additive manufacturing (AM) holds immense utility. Herein, three samples of 3D‐printed material specimens namely acrylonitrile butadiene styrene (ABS), polylactic acid (PLA) and polylactic acid + carbon fiber (PLA + CF) are fabricated at 0°, 45°, and 90° orientations using fused deposition modeling (FDM) and subsequently their mechanical properties are evaluated. Scanning electron microscopy (SEM) images are presented to observe the failure behavior. The uncertainty analysis performed on measured and obtained parameters reveals the maximum error of ±0.312% and ±0.3218%, respectively. From the obtained experimental results, correlations on average tensile strength in terms of elastic modulus, percent strain, standard deviation, and printing orientations are presented for each of the materials. ABS and PLA + CF specimens show the agreement of co‐relational with experimental data which lies within ±10% whereas ±3% for PLA specimens. Although on reinforcing with CF, the strength of PLA + CF samples increases considerably at all orientations as compared to PLA and ABS, virgin PLA reported greater elastic modulus as compared with PLA + CF, therefore virgin PLA finds better utilization wherever stiffness is the key requirement in design.

“…Köszönhetően a 3D nyomtatás térhódításának egyre több tudományos cikk foglalkozik a különböző 3D nyomtatási paraméterek mechanikai tulajdonságokra gyakorolt hatásával. A témában megjelenő cikkek többsége azonban a 3D nyomtatási paraméterek folyáshatárra vagy szakítószilárdságra gyakorolt hatásával foglalkozik (Srinivasan et al, 2020;Dorčiak et al, 2019;Tandon et al, 2021). Természetesen szép számmal akadnak olyan publikációk is, amelyek valamely paraméter ütőmunkára gyakorolt hatásával foglalkoznak.…”

Ezen tanulmány célja, hogy megvizsgálja az FDM 3D nyomtatásnál gyakran alkalmazott Cura programban található különböző kitöltési mintázatok ütőmunkára gyakorolt UNI EN ISO 180 szabványú hornyolatlan PLA próbatestek segítségével. Mivel az említett programban több, mint 10 féle különböző kialakítású kitöltésből választhatunk, így mind a hobbi célú mind pedig az ipari felhasználók számára kulcsfontosságú kérdés, hogy az egyes kitöltések esetében az elkészülő alkatrész milyen mechanikai tulajdonságokat produkál. Emellett fontos megállapítani, hogy létezik-e olyan mértékű különbség az egyes kitöltések által biztosított mechanikai tulajdonságok között, amely már esetlegesen veszélyezteti az egyes alkatrészek használhatóságát. A tanulmányban fontos szerepet kap annak megállapítása, hogy az ütőmunka szempontjából melyek a legkedvezőbb és legkedvezőtlenebb kitöltési mintázatok.

Fused filament fabrication (FFF) is an Additive manufacturing technique, widely used in engineering that involves adding material layer by layer to create solid objects with complex geometry. Due to the poor mechanical performance of pure thermoplastics materials, one alternative for enhancing the mechanical qualities of FFF created thermoplastic parts is to include reinforcing material, such as carbon fibre (CF). In this work, we perform an FFF analysis of the mechanical behaviour of gyroid infilled CF based poly-lactic-acid (PLA) composites. Tensile behaviour is measured for a variety of parameter combinations, including raster angle (RA) (0°, 45°, 90°), feed rate (FR) (20 mm/s, 40 mm/s, 60 mm/s) and layer height (LH) (0.1 mm, 0.15 mm, 0.2 mm). By adjusting the several process parameters, it is possible to increase tensile strength (TS) by 70.81%, from a minimum of 16.17 MPa to a maximum of 27.62 MPa. The failure mechanisms of the studied specimens are determined using a fractography study, which indicates pulling, necking, raster failure, and voids. Using ANOVA, Taguchi’s L27 array, and regression analysis, the impact of LH, RA, and FR on TS is determined, in which, LH having the highest influence. The results of this study will aid engineers in creating useful components with improved mechanical behaviour.
