Functional Behavior and Energy Absorption Characteristics of Additively Manufactured Smart Sandwich Structures

Additive manufacturing (AM) of functional parts using smart materials has attracted considerable interest in both scientific and industrial domains. The application shape memory polymers (SMPs) opens up new possibilities the fabrication process makes them able to recover their initial after deformation. This study aims demonstrate synergic potentiality SMPs fused filament (FFF) manufacture 4D printed sandwiches address behavior. technological solution promises lightweight biodegradable parts, which boast exceedingly valuable performance reusable energy absorbing applications. Several designs, materials, parameters including nozzle temperature, layer height, printing speed are investigated this work. results show that selecting appropriate core geometries could enhance mechanical strength as well deformation capability sandwich structures. Likewise, applied considerably affect absorption characteristics. Moreover, tweaking is found be a useful approach for maximizing properties displacement 4D-printed sandwiches.
