FDM material guide: TPU / flexible

TPU and flexible filaments: elasticity, damping and soft parts

TPU and flexible filaments are used to produce soft, impact-resistant parts that can deform without breaking. Selection depends on Shore hardness, layer bonding, possible print speed and extruder compatibility.

• Seals and protectionPads, bumpers, simple seals and damping elements.
• Wearable partsBands, grips, cases and contact elements.
• RoboticsTires, soft grippers, feet and anti-vibration zones.
• Workshop toolingTips, guards, spacers and non-slip surfaces.
• Ergonomic prototypesGrip, flex and impact absorption testing.
• MaintenanceReplaceable soft parts outside certified constraints.

Material advice : check Shore hardness and extruder compatibility before ordering. For semi-rigid parts, TPU 95A is often easier than very soft TPU.
