“…However, the temperature and printing speed were adapted depending on the characteristics of the filaments, allowing the best printing conditions. [19][20][21][22] The agricultural tube prototypes and tensile test specimens were printed on a Creality Ender-3 3D Printer using the FDM method. The tensile test specimens were produced in two different filling orientations: À45/45 and 0/90 , while the tubes were produced only with the 0/90 filling orientation, as identified in Figure 2.…”

Additive manufacturing, which has become popular in recent years, is the process of joining materials through the deposition of layers to form parts based on data from a 3D model and fused deposition modeling. The search for biodegradable materials for the production of filaments for 3D printing is increasing and opening up possibilities for the development of new sustainable products, including the use of lignocellulosic waste in the formulation. Therefore, the present work aims to develop polymeric filaments based on polybutylene adipate terephthalate and low content (2.5 and 5 wt%) of peanut and soybean shells and evaluate their potential for 3D printing. The charges were characterized in terms of chemical composition. Tensile and dimensional variation tests were performed on samples manufactured from two different filling orientations: −45/45° and 0/90°. The printability of the filament was based on the manufacture of prototypes of agricultural tubes that were also characterized by thermogravimetry and their morphology through scanning electron and optical microscopy. Both natural residues significantly (p < 0.05) affected the sample dimensions and mechanical properties. However, the filling orientation difference was insignificant (p > 0.05). The filaments produced showed good processability, thermal and dimensional stability. The samples produced showed a satisfactory surface finish without exposing load agglomerates. These results demonstrate the feasibility of using lignocellulosic fillers, such as peanut and soybean shells, in additive manufacturing and indicate the possibility of producing parts with varied geometries.Highlights Use of lignocellulosic residues in biodegradable filaments. The filament produced with fillers of peanut and soybean shells showed good processability. Filament fracture depends on the raster angle. It was possible to produce tubes with good surface quality and mechanical properties.

“…Attention to these parameters ensures optimal results and high‐quality prints 6 . Study conducted by Benamira et al 7 systematically explores the primary and interaction effects of printing orientation and layer thickness on the mechanical failure characteristics, considering two distinct levels of infill density (40% and 100%). It posits that specimens featuring 100% infill density demonstrate heightened sensitivity to interaction performance, whereas main effects are discernibly more pronounced in specimens with a 40% infill density 7 .…”

The primary objective of this research is to investigate the impact of strain rate on the mechanical properties of polylactic acid (PLA) fabricated through fused deposition modeling. PLA material was fabricated in a grid pattern with 75% infill density, a 0.16 mm layer height, and a ± 45° printing direction. This study specifically investigated tensile strength, flexural strength, and interlaminar strength with respect to varying crosshead speeds (1, 2, 3, 4, and 5 mm/min). The highest tensile strength noted was 40.13 MPa at a cross—head speed of 5 mm/min. Maximum elongation of 7.1% was noted on cross head velocity of 1 mm/min, and the maximum interlaminar strength reached 76.04 MPa at 4 mm/min. At a crosshead speed of 4 mm/min, the tensile strength measured was 38.36 MPa, which is a value close to the maximum result achieved in the tensile test. Interlaminar strength was notably higher at a crosshead speed of 4 mm/min, indicating a strong integrity of the printed layers. The values for elongation percentage and flexural strength were also moderate at a crosshead speed of 4 mm/min, which was 4.9% and 55 MPa, respectively. Therefore, crosshead speed of 4 mm/min appears to be an optimum factor for testing 3D printed PLA parts. This research sheds light on understanding the critical influence of strain rate in the mechanical performance of 3D printed PLA.

“…Belonging to Industry 4.0, additive technologies offer the possibility to set values for a large variety of technological parameters of 3D printing, which have an impact on the properties of the manufactured finished product (Benamira et al, 2023;Do et al, 2022;Kadhum et al, 2023;Oleksy et al, 2019). The assessment of the effect of 3D printing parameters (print orientation 0°, 45°, 90° and layer heights of 0.6 mm, 0.7 mm, 0.8 mm) on the bending of resin and carbon fibre-reinforced T-bars presented in the publication is an example (Wu et al, 2022).…”

The technological parameters of 3D printing have a significant impact on the mechanical properties including rheological properties of models produced by additive technology. Research on the influence of these parameters is important for designers who design machine components. Therefore, this article presents extensive research on the influence of the 3D printing technological parameter of the number of shells (2 and 10) on selected mechanical properties. Two different types of specimens produced by FDM (Fused Deposition Modelling) technology were used from PLA material. The selected mechanical properties were tensile strength, flexural strength and creep phenomenon. The five-parameter Kelvin-Voight model was used to describe the creep curve obtained from the tests. Very good fits were obtained, which allows us to recommend the obtained results for engineering calculations. The research results presented in this article showed that for both tensile strength, flexural strength and creep phenomenon, higher values were obtained for the number of shells 10 compared to the number of shells 2.
