Flexible Additively Manufactured Honeycombs Under Impact Loading: Effect of Topology and Orientation

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Additive manufacturing enables the fabrication of lightweight cellular lattices with tailorable mechanical behavior. This study examines the low‐velocity impact response of thermoplastic polyurethane (TPU) honeycombs produced by fused filament fabrication (FFF) and tested using an Open Hopkinson Pressure Bar (OHPB) system. Five topologies—square (Sqr),
