TPU Flex Filament - 93A
Eolas Prints TPU Flex 93A is a flexible filament with Shore 93A hardness — the sweet spot between firm elasticity and soft flexibility. Manufactured in Cantabria, Spain, from thermoplastic polyurethane, it delivers professional-grade durability for a wide range of functional applications. Made from food-contact-safe certified raw material.
Key Properties
| Shore hardness | 93A — medium-soft flexibility |
| Density | 1.21 g/cm³ |
| Diameter tolerance | ±0.08 mm |
| Food-contact-safe raw material | Yes — virgin pellets and masterbatches certified to EU food-contact standards (see note below) |
| Skin contact safe (raw material) | Yes |
| Toy safe (raw material) | Yes |
| Recyclable | Yes |
| Chemical resistance | Excellent (oils, cleaning agents) |
| Wear resistance | Superior in high-friction applications |
| Extruder compatibility | Direct drive recommended; short Bowden possible |
A Note on Food Contact
Our food-contact certification applies to the raw filament material — the virgin pellets and masterbatches we manufacture from — not to finished printed parts. 3D-printed surfaces contain microscopic gaps between layers that can harbour bacteria, and most printers use brass nozzles that may introduce trace metals into the print. For this reason, no 3D-printed object can be guaranteed food-safe by the filament alone. If you intend a part for food contact, print it with a stainless-steel nozzle and apply a food-safe sealant — and assess suitability for your specific use. This remains the responsibility of the maker.
Recommended Print Settings
| Nozzle temperature | 220–235°C |
| Bed temperature | 50–60°C |
| Print speed | 15–30 mm/s |
| Retraction | 0.5–1 mm (minimal) |
| Cooling fan | 50–80% |
| Extruder | Direct drive recommended |

TPU is sensitive to speed and retraction — these guides help you get it right: our PETG, TPU & ASA settings guide, how to fix stringing and oozing, and first-layer & bed-adhesion troubleshooting. For flexible prints, pair it with Magigoo Pro Flex. For everything in one place, see our complete troubleshooting & calibration guide.
Shore Hardness in Context
93A sits between our softest grade (D53 — like a rubber eraser) and our firmest (D60 — like a hard rubber sole). At 93A, the filament feels like a car tyre: flexible and resilient, but with enough firmness to hold structure. It is the most versatile TPU grade for general-purpose flexible printing.
Recommended Applications
- Kitchen accessories and food-preparation aids (with appropriate food-safe sealing — see note above)
- Protective phone cases and wearable components
- Automotive gaskets, seals, and vibration dampeners
- Orthopaedic supports and prosthetic elements
- Industrial gaskets, protective covers, and flexible connectors
- Functional flexible prototypes and product validation models
Manufactured in Spain
Manufactured at Eolas Prints' facility in Cantabria, Spain, under ISO 9001 and ISO 14001 standards. Available in 1.75mm and 2.85mm in 40 colours.
