Integrating dynamic functionalities into 3D-printed optical components has remained a major challenge, leaving printed optics limited to static behavior. Electrically tunable materials such as the conducting polymer PEDOT:PSS offer a promising route toward adaptive, and compact optoelectronic systems. A key bottleneck has been the high-resolution patterning of PEDOT:PSS. However, we recently introduced two direct nanofabrication strategies that overcome these limitations: electron-beam-induced solubility modulation, and laser-based patterning using the same systems employed for two-photon polymerization of optical resins. The latter method enables true nanoscale patterning and is fully compatible with 3D-printed micro-optics. Using these techniques, we present a versatile integration scheme in which tunable PEDOT:PSS structures are positioned either beneath or atop static 3D-printed elements. This hybrid platform enables voltage-controlled transitions between dark-field and bright-field operation at CMOS-compatible voltages from -2 V to +2 V. The approach establishes a robust foundation for future reconfigurable photonic components.
