| dc.description | This research evaluated the combined effect of infill percentage and infill pattern on the specific mechanical properties of standard PLA parts manufactured by fused deposition modeling (FDM). Two bioinspired patterns, wood and bamboo, were selected through the Analytic Hierarchy Process (AHP), and specimens were designed with three infill levels: 25%, 50%, and 75%. The samples were fabricated by FDM and tested under compression and impact loading according to ASTM D695 and ASTM D256 standards, respectively. In addition, the apparent density of each configuration was determined to calculate specific mechanical properties, including compressive strength and absorbed energy per unit apparent density. The results showed that mechanical performance was not exclusively governed by infill percentage but also by its interaction with the internal geometry of the pattern. The bamboo-inspired pattern with 50% infill exhibited the best specific impact performance, whereas the 50M and 75M configurations (50% and 75% wood-inspired patterns, respectively) showed the highest specific performance under compression. Furthermore, configurations with higher infill percentages exhibited local stiffening effects that reduced the plastic deformation capacity of the structures. Overall, the findings indicate that bioinspired infill patterns can be used as a design strategy to improve the structural efficiency of FDM-printed components, particularly in applications where weight reduction and material savings are required without compromising mechanical performance. | en-US |
| dc.description | Esta investigación evaluó el efecto combinado del porcentaje y el patrón de relleno sobre las propiedades mecánicas específicas de piezas fabricadas en PLA estándar, mediante modelado por deposición fundida (FDM). Como metodología, se seleccionaron dos patrones bioinspirados, madera y bambú, mediante el proceso de jerarquía analítica (AHP), y se diseñaron probetas con tres niveles de relleno: 25 %, 50 % y 75 %. Las muestras fueron fabricadas por FDM y se evaluaron a compresión e impacto según las normas ASTM D695 y D256. Además, se determinó la densidad aparente para calcular propiedades mecánicas específicas, como la resistencia a compresión y la energía absorbida por unidad de densidad aparente. Los resultados mostraron que el desempeño mecánico no dependió únicamente del porcentaje de relleno, sino también de su combinación con la geometría interna del patrón. El patrón bambú, con 50 % de relleno, presentó el mejor comportamiento específico en impacto, mientras que las muestras 50 M y 75 M (50 % y 75 % con patrón de madera, respectivamente) destacaron en compresión. Asimismo, las configuraciones de mayor porcentaje de relleno evidenciaron una rigidización local, que redujo la deformación plástica de los materiales. Finalmente, se concluyó que los patrones bioinspirados pueden emplearse como estrategia de diseño para mejorar la eficiencia estructural de piezas impresas por FDM, especialmente cuando se requiere reducir peso y consumo de material sin afectar el desempeño mecánico. | es-ES |
