This study evaluates the ultimate tensile strength (UTS) and surface roughness in 3D-printed Nylon PA66 for three standard infill patterns (starred, concentric, and linear) and two novel combined designs (starred-concentric and starred-linear). Extrusion temperature was considered as a secondary variable (260 °C, 270 °C, and 280 °C), while infill density was kept constant at 80% for all designs. The hybrid patterns increased UTS by up to 50% compared to the conventional ones, demonstrating superior mechanical performance. However, increased strength often coincides with higher roughness, particularly at elevated temperatures, revealing an inverse relationship under certain conditions. In addition, the failure mode varied with temperature; while low temperatures caused premature delamination between layers, a cohesive bond was achieved with the Star-Linear pattern at 280 °C. These findings underscore the importance of pattern design and thermal parameters in optimizing the mechanical and surface properties of printed parts. © The Author(s), under exclusive licence to The Materials Research Society 2026.

The objective of this research was to find a relationship between the microstructural and macrostructural properties of polylactic acid, acrylonitrile butadiene styrene and polyamide 12 (PA12) when processed using fused deposition modelling. The crystallinity, enthalpy of crystallization (ΔHc), glass transition temperature (Tg) and Young's modulus (E) were evaluated. The results showed that crystallinity increased for all materials after the 3D printing process, leading to an increase in ΔHcand a decrease in Tg, particularly in PA12. This variation in microstructural properties resulted in a significant decrease in Young's modulus, indicating a reduction in the stiffness of the printed materials. The research suggests that an increase in crystalline material volume, resulting from polymer chain rearrangement during 3D printing, reduces the energy required for thermal softening and decreases the material's rigidity. © The Author(s) 2025
