Material Profile
TPU 95A offers the best compromise between printability, shape stability and elasticity. With Shore hardness 95A, the material is still noticeably more flexible than rigid polymers like PLA or PETG, but processes considerably more easily than the softer 85A and 90A variants.
The material is suited for technical functional parts that need some elasticity but should still be shape-stable enough: belt replacements, protective covers, contact parts.
What Does Shore Hardness Mean?
Shore hardness describes the indentation hardness of elastic plastics. For TPU: the lower the Shore A value, the softer and more flexible the material. TPU 95A is more shape-stable than 85A/90A but significantly more elastic than rigid TPU 98A.
Important: The actual flexibility of a part depends not only on Shore hardness but also on part geometry, wall thickness, infill density, print direction, temperature and the specific manufacturer’s filament.
TPU Variant Comparison
| Material | Shore hardness | Flexibility | Printability | Typical application |
|---|---|---|---|---|
| TPU 85A | 85A | very flexible | demanding | soft seals, dampers, protective caps |
| TPU 90A | 90A | flexible | medium | seals, mounts, vibration dampers |
| TPU 95A | 95A | semi-flexible | good to medium | technical flexible parts, protective parts |
| TPU 98A | 98A | slightly flexible | good | robust tough-elastic functional parts |
Design Notes for TPU 95A
TPU 95A can be designed well for belts, rollers and contact parts. Stiffness in the part is controlled by wall thickness and infill – thinner cross-sections stay flexible, solid geometries behave almost like a rigid polymer.
