4D Print Path Planner

Design multi-material print schedules for shape-morphing SMP structures. Configure active and passive material zones, fiber orientation angles, and stimulus sequences to predict shape change, curvature, and actuation energy for wearable, biomedical, and aerospace applications.

Based on digital shape memory polymer composite research · Voit et al. (UTD APRL) · Ge et al. Georgia Tech · Adaptive 3D DART platform · Multi-material FFF and DLP processes
