Structure–Property Relationships and Energy Absorption of FFF-Manufactured PETG Honeycomb-Type Structures for Automotive Applications
This study explores the quasi-static and dynamic responses of irregular, honeycomb-like topologies made from glycol polyethylene terephthalate (PETG) with various sparse infill densities, using fused filament fabrication (FFF) manufacturing technology. Both tensile and flexural tests revealed a linear increase in Young...
