Overview

Experimental design reveals improved impact resistance in sandwich structures, suggesting optimal build orientation and infill geometry.

Key Points

  • Upright-printed specimens showed up to 68% higher peak force compared to flat-printed designs, enhancing impact resistance.
  • The maximum contact force was used as the primary response variable, revealing significant differences in performance.
  • Three-factor, three-level full factorial experimental design assessed build orientation, infill pattern, and impact energy effects.
  • Findings support the use of optimal infill patterns for improved energy absorption in engineering applications.
