Where it fits
TPU Filament is a sensible starting point for feet, bumpers, grips, seals, and flexible protective parts.
Why makers choose it
Its practical appeal is elastic recovery and impact cushioning.
Trade-offs to plan for
slow, controlled feeding and careful retraction tuning.
Print, shrinkage, and moisture notes
Flexibility changes both feeding and part design. Dry filament and a constrained filament path help; use a geometry that can flex instead of expecting a thick block to behave like rubber.
Material names describe a family, not a guaranteed result. Formulation, color, reinforcement, annealing, orientation, and your printer can change behavior. Use the supplier technical data for critical tolerances, heat exposure, or safety requirements.
