Abstract
This work investigates the development of a fully 3D printed strain sensor using conductive Thermo-plastic Polyurethane elastomer (TPU) and Polylactic Acid (PLA) filaments. The sensor is produced solely through additive manufacturing Fused Deposition Modeling (FDM) technology. This process is particu-larly beneficial in maritime environments as it enables remote production, thereby reducing downtime, minimizing inventory demands, and lowering environmental impact. The use of conductive TPU com-pared to previously performed research employing CNT-enriched PLA filament results in expandedmeasuring range and reduced hysteresis, mainly attributed to the elasticity of the building material. The developed sensor maintains the key advantages of a fully 3D printed device, including robustness, astraightforward design, and a single-step manufacturing process, while offering a reliable electrical in-terface through standard soldering. These combined features enhance its reliability, durability, and over-all suitability for structural monitoring applications in marine environments.
