Effect of Infill Density on the Mechanical Properties of Natural Peek Processed by Additive Manufacturing

Polymers, Год журнала: 2025, Номер 17(3), С. 347 - 347

Опубликована: Янв. 27, 2025

In the present investigation, mechanical properties of natural polyether-ether-ketone (PEEK), processed by additive manufacturing applying fused deposition modeling (FDM) with three different infill densities, are investigated. Mechanical characterization was performed through destructive testing. Specimens were designed in CAD software and printed controlled densities 40%, 70%, 100%, using a rectilinear pattern. The results showed that increased density improves strength stiffness but reduces ductility energy absorption capacity. For considered maximum stress levels reach values 107.53±6.29MPa, 114.32±11.95MPa, 63.96±2.39MPa, respectively, against compression, bending, tensile loading. These findings offer crucial information for optimizing high-strength components industrial biomedical applications. As result, practical guidelines provided design medical devices, such as implants, achieving an appropriate balance between performance material efficiency.

Optimization of Compressive Strength Properties in Fused Deposition Modeling 3D Printed PLA/HA Composites for Bone Tissue Engineering Applications

Engineering Reports, Год журнала: 2025, Номер 7(5)

Опубликована: Май 1, 2025

ABSTRACT This study investigates the optimization of 3D‐printed polylactic acid (PLA) and hydroxyapatite (HA) composites for biomedical applications, focusing on enhancing mechanical properties through process parameter surface modification. The response methodology (RSM), along with post hoc statistical validation using Tukey's HSD test, was employed to evaluate influence nozzle temperature (200°C–240°C), layer height (0.1–0.3 mm), HA filler ratio (3–9 wt%) compressive strength both untreated chemically treated composites. Silane treatment applied improve interfacial bonding, resulting in a 5%–7% increase compared samples. optimal conditions (240°C, 9% HA, 0.3 mm thickness) yielded maximum 75.35 MPa 71.42 Statistical analysis confirmed that thickness content significantly influenced performance. Contour plots 3D surfaces were also incorporated visualize interactions. Comparison other techniques demonstrated RSM effectively minimized experimental runs while achieving superior properties. These findings suggest modified PLA/HA are promising candidates load‐bearing applications.

Optimization of Tensile Strength Behavior in 3D‐Printed PLA With 10% Terminalia chebula Nanocomposites: Influence of Strain Rate, Orientation, and Infill Percentage

Engineering Reports, Год журнала: 2025, Номер 7(5)

Опубликована: Май 1, 2025

ABSTRACT This study aims to investigate and maximize the tensile strength behavior of polylactic acid (PLA) 90% Terminalia chebula nanoparticle (TCNP) 10% composites fabricated using fused deposition modeling (FDM) under varying strain rates (3, 6, 9 mm/min), orientations (0°, 45°, 90°), infill percentages (30%, 60%, 90%). The was analyzed assess combined influence these parameters on mechanical performance composites. At a low rate 3 mm/min, exhibited highest due enhanced molecular alignment stress redistribution, achieving maximum values in 0° orientation across all percentages. Increasing reduced strength, with material transitioning from ductile brittle failure, especially at where rapid deformation hindered realignment. consistently demonstrated superior efficient load transfer along printed layers, while 90° weakest performance, attributed concentrations interlayer bonds. Higher percentages, 60% 90%, improved density, enhancing but diminishing higher rates. highlights optimal 45.67 ± 2.28 MPa, which achieved infill, mm/min rate, orientation, making it suitable for load‐bearing applications. findings provide insights into tailoring 3D‐printed PLA‐TCNP specific applications, balancing ductility, controlled failure mechanisms.
