Product Features
Flexible material with the same elasticity as rubber.
The thinner and less filled the printed model is, the higher elasticity and softness it gets.
Low viscosity, easy to cooling.
Uvioresistant.
Application
Generally used for printing elastic products, suitable for all groups who want to print soft models.
Technical Specification
Filament Diameter: 1.75mm
Tolerance: ±0.05mm
Printing Temperature: 200°C-220°C
Heated Bed Temperature: 0°C-60°C/ without heating
Printing Speed: 15-40mm/s
Shore Hardness: 95A
Shortcomings
TPU is soft material, so the filament can’t be rolled neatly.
The material itself is soft and does not bear any force. It is recommended to use the direct drive extruder to get a good printing experience. The remote extruder can only print normally after modification.
Bowden extruder is difficult to use and requires high level of users.
