Characterization and Design of 3D Printed Composite Insole Fabricated by Dual-Nozzle 3D Printer Using CB-PLA and Fe-PLA Filaments
This study develops and characterizes dual-nozzle 3D printed smart insoles using PLA sheaths with carbon black or iron-filled PLA cores, demonstrating that integrated structures with larger core diameters and thinner profiles significantly enhance electrical conductivity and magnetic field strength for plantar pressure sensing applications.
