Direct ink writing (DIW) has emerged as a promising additive manufacturing technique for fabricating three-dimensional electrode architectures with controlled structural features and high design flexibility. MXenes (Ti<inf>3</inf>C<inf>2</inf>T<inf>x</inf>), owing to their metallic conductivity, surface functionality, and viscoelastic properties, serve as excellent platforms for developing composite electrodes. In this work, we report for the first time the in-situ interfacing of 0D Cu-Ni-O-FPs/MXene as cathode and 0D α-Fe-O-FPs/MXene as anode materials, followed by their integration into a DIW-printed asymmetric supercapacitor (ASC). The Cu-Ni-O-FPs/MXene cathode exhibited an areal capacity of 1.23 mA h cm⁻² at 1 mA cm⁻², with a rate capability of 75.60 % at 80 mA cm⁻² and long-term cycling stability of 93.8 % after 10,000 cycles. The α-Fe-O-FPs/MXene anode delivered an areal capacity of 0.69 mA h cm⁻² at 1 mA cm⁻², demonstrating excellent charge-storage characteristics. When assembled, the DIW-printed Cu-Ni-O-FPs/MXene//α-Fe-O-FPs/MXene ASC achieved a remarkable energy density of 69.25 Wh kg⁻¹ at a power density of 380.1 W kg⁻¹, and 49.22 Wh kg⁻¹ at an ultra-high power density of 10,010.85 W kg⁻¹, along with 90.86 % retention after 10,000 cycles. This study establishes a new design paradigm for DIW-printed energy storage devices by leveraging the strong interfacial coupling between 0D pseudocapacitive nanoparticles and 2D MXene nanosheets. The unique 0D/2D pseudocapacitive-driven hybrid architectures ensure maximized redox contributions, minimized charge-transfer resistance, and well-balanced electrode kinetics.
