Implication

Randomized trial explores mechanical performance and energy efficiency in PLA+flax composites, suggesting optimal configurations for manufacturing.

Key Points

This study aims to investigate the effects of part thickness and infill strategies on the mechanical performance and energy efficiency of PLA+flax composites fabricated by FFF.
Investigated different part thicknesses and infill architectures in PLA+flax composites.
Examined mechanical performance under low-velocity impact and energy consumption during fabrication.
Evaluated configurations including gyroid and hexagonal infill patterns.
Gyroid structure exhibited the highest penetration energy at 16.07 J, surpassing the fully solid configuration.
Volumetric specific energy consumption improved from 66.9 kJ/cm³ for 2 mm to 25.9 kJ/cm³ for 6 mm specimens, showing enhanced manufacturing efficiency.
Thicker parts did not always correlate with better mass-normalized performance, indicating a need for optimal infill architecture.
