Abstract
Fused Deposition Modelling technology was used to fabricate a working gas sensor to detect VOCs. The sensors were fabricated by incorporating metal oxide-based material, specifically tungsten oxide, with polycaprolactone. The mixture was made into pellets and extruded using a filament extruder. The best combination was found to be at 85% WO3 in WO3−PCL mixture. A modified FDM printer was used to print the gas sensitive material onto a sensor substrate made of alumina. The gas testing results demonstrated that the sensors could detect 100 ppm isobutylene and ethanol at up to 5 ppb.
