Effects of Node Fillet Radius on Compressive Properties and Energy Absorption of FDM-Fabricated PETG Auxetic Honeycombs
Node fillet radius has a pronounced effect on the compressive performance of fused deposition modeling (FDM)-printed polymer honeycombs, yet quantitative design guidelines for PETG auxetic structures remain scarce. The effects of gradient node fillet radii (R0–R7 mm) on the load-bearing capacity, deformation mechanisms...
