| Topic | Guidance |
|---|---|
| Typical, not minimum | The property tables describe specimens printed exactly as stated in Section 5. They describe the material, not a machined or moulded part. |
| Orientation matters | Values marked X·Y apply to specimens printed flat on the build plate. Z values are measured on parts printed standing up and are typically lower than X·Y. Design for the direction that carries the load. |
| Batch variation | Values carry a ± range where extrusion, pigment and ambient humidity vary between batches; colour masterbatch can shift impact strength noticeably. Where no deviation is given, the value is a single representative test. |
| Not a certificate | This sheet is not an inspection certificate, a Declaration of Conformity, or a certificate of analysis. Batch-specific CoA, RoHS / REACH declarations and safety data sheets are issued separately on request. |
Technical data sheet
Storage, handling & safety.
| Topic | Guidance |
|---|---|
| Storage before use | Sealed bag with desiccant, 15 – 25 °C, below 50 % RH, away from direct sunlight and UV. Shelf life 24 months in the sealed bag. |
| Storage after opening | TPU picks up moisture faster than PLA or PETG. Reseal immediately after use and re-dry before any critical print: 50 – 60 °C for 6 – 8 h. |
| Symptoms of moisture | Severe bubbling, popping and hissing at the nozzle, foamy extrusion, poor surface finish, weak layer bonding. Dry before changing any settings. |
| Handling | Flexible filament must be guided over the shortest possible path. Avoid tight bends and small-diameter guides; a direct-drive extruder with a short bowden is strongly preferred. |
| Ventilation | Printing releases low levels of isocyanate-related volatiles and a noticeable odour. Print in a well-ventilated area or under extraction, especially for long jobs. Not for use in enclosed occupied spaces without extraction. |
| Fire and disposal | TPU is a combustible solid. Keep away from open flame and hot surfaces above 240 °C. Spool, bag and carton are recyclable; offcuts are not biodegradable and should go to plastics recycling. |
| Personal protection | No special protection required for normal use. Wear gloves when handling hot parts and safety glasses when cutting filament. |
