Support-Free TPU Flexure Mechanism

Compliant MechanismsAdditive ManufacturingTPUFDMMechanical Design

Monolithic TPU compliant mechanism designed for support-free FDM printing — a single-piece flexible structure with no joints or assembly, optimized for Bambu Labs printers.

  • Modeled a flexure-based compliant mechanism in CAD for support-free FDM printing
  • Designed internal cavities to control elastic deformation without mechanical joints
  • Optimized geometry for Bambu Labs FDM — no overhangs over 45°, no supports required
  • Iterated on wall thickness and cavity spacing to tune stiffness and bending behavior
