Frequently Asked Questions
How many meters of TPU 85A (Ultra-Flexible) filament are in a 1kg spool?
A standard 1,000g (1 kg) spool of 1.75mm TPU 85A (Ultra-Flexible) filament (density 1.18 g/cm³) contains approximately 352.33 meters (~1156 feet). For 2.85mm diameter, a 1 kg spool yields approximately 132.84 meters.
What is the density of TPU 85A (Ultra-Flexible) 3D printer filament?
TPU 85A (Ultra-Flexible) has an average density of 1.18 g/cm³. Heavier composite filaments yield fewer meters per kilogram than lightweight unfilled polymers.
How do I calculate remaining TPU 85A (Ultra-Flexible) on a used spool?
Weigh your spool on a digital scale in grams, subtract the tare weight of the empty spool (typically 130g–240g depending on brand), and enter the net filament weight into the MakersMetric calculator above to find the exact remaining meters.
What print temperatures are recommended for TPU 85A (Ultra-Flexible)?
Recommended nozzle extrusion temperature is 215-235 °C, with a recommended print bed temperature of 30-50 °C.
