The development of polymer-based systems is central to the design of next-generation drug delivery carriers, as polymers enable versatile tuning of physicochemical properties and responsiveness. In this work, we introduce a 3D printing-based strategy for the fabrication of multicompartment capsules that integrate multiple polymers within a unique one-step process. This approach allows precise spatial organization and structural complexity, yielding capsules with customizable features such as compartmentalization, polymerspecific responsiveness, and localized release control. In particular, pH-triggered release can be programmed across distinct polymeric regions of the capsules, enabling site-specific delivery along different intestinal segments, including the small intestine and colon. The use of 3D printing thus provides a scalable and adaptable platform to generate multifunctional polymer-based carriers with finely tunable drug release profiles, paving the way for new directions in polymer-enabled controlled delivery technologies.
