Xstrings integrates cable-driven mechanisms directly into dual-material 3D prints, enabling complex actuation such as bending, coiling, screwing, and compressing without post-assembly. Cables are embedded within the printed object using flexible joints and channels formed layer by layer. When force is applied to the cables, the structure moves as designed. Reducing assembly time by 40%, this approach supports rapid prototyping of soft robotics, adaptive systems, and compact actuators using low-cost, accessible desktop 3D printing technology
