TPU (Thermoplastic Polyurethane) flexible parts require specialized low-speed extrusion (15-30 mm/s) to prevent filament buckling in direct drive extruders. As a result, TPU print times are 2x to 3x longer than rigid materials, driving up machine depreciation and hourly power costs.
Mathematical Formula Breakdown
TPU Cost is driven heavily by Machine Overhead (Hours × Machine Hourly Rate) due to slow volumetric flow rates (typically 2-4 mm³/s max).
Industry Pricing Benchmarks
TPU spools cost $35 - $60 per kg. Custom flexible seals, gaskets, and phone cases command $0.30 - $0.50 per gram in custom print shops.
Optimization Strategies
- Use direct drive extruders to allow higher speed settings without clogging.
- Keep retractions low (0.5mm max) to avoid grinding flexible filament in drive gears.
Frequently Asked Questions
Why are TPU prints so expensive?
Because TPU must be printed very slowly to avoid extruder jams, a part that takes 3 hours in PLA can take 9 hours in TPU, tripling the machine labor cost.
