Background:

• Three-dimensional (3D) printing offers novel, low-cost material fabrication.
• Conductive filaments enable the creation of 3D printed platforms.

Purpose of the Study:

• To develop and evaluate 3D printed electrodes (3DEs) using a graphene-based conductive filament.
• To demonstrate the potential of these 3DEs in energy storage and sensing applications.

Main Methods:

• Fabrication of 3DEs using a commercial 3D printer and a printable graphene-based conductive filament.
• Physicochemical and electrochemical characterization of the 3DEs.
• Integration of 3DEs into supercapacitor and photoelectrochemical sensor prototypes.

Main Results:

• The 3DEs were successfully fabricated without ex-situ modification or post-treatment.
• The supercapacitor achieved a specific capacitance of 98.37 Fg⁻¹.
• The photoelectrochemical sensor exhibited a photocurrent response of ~724.1 μA and a low detection limit of 0.05 μM.

Conclusions:

• 3D printing provides a facile, low-cost method for producing conductive electrodes.
• The developed 3DEs are suitable for fabricating high-performance supercapacitors and sensitive photoelectrochemical sensors.
