TPU 95A HF Print Settings
Expert-recommended TPU 95A HF (TPU) settings for all Bambu Lab printers
Why use TPU 95A HF?
- High-flow TPU formula designed for AMS compatibility
- Shore 95A hardness — firm but flexible (like a shoe sole)
- Excellent for phone cases, bumpers, seals, and gaskets
- Chemical and abrasion resistant
- Vibration dampening properties for mounts and enclosures
- Prints significantly faster than standard TPU formulations
What are the best TPU 95A HF print settings?
Use default Bambu Lab temperature profiles for TPU 95A HF. Recommended outer wall speed is 80 mm/s.
| Setting | Value | Note |
|---|---|---|
| speed.layers.outerWall | 80 | TPU requires significantly slower outer walls |
| speed.layers.innerWall | 100 | Slow inner walls for flexible material |
| speed.layers.sparseInfill | 150 | Very slow infill for TPU |
| speed.layers.internalSolidInfill | 100 | Slow solid infill |
| speed.layers.topSurface | 80 | Slow top surface for TPU |
| speed.initial.layer | 25 | Very slow first layer for TPU adhesion |
| speed.initial.infill | 50 | Slow initial infill |
| speed.travel | 500 | Reduced travel speed — TPU oozes at high travel |
| speed.layers.bridge | 25 | Very slow bridges for flexible material |
| speed.layers.gapInfill | 80 | Slow gap infill for TPU |
| speed.accel.normalPrinting | 3000 | Low acceleration prevents TPU buckling in extruder |
| speed.accel.outerWall | 2000 | Low outer wall acceleration |
| strength.walls.wallLoops | 3 | More walls for flexible parts integrity |
| strength.infill.density | 20 | Higher infill for TPU structural support |
| strength.infill.pattern | Gyroid | Gyroid provides even flex in all directions |
| quality.advanced.avoidCrossingWall | true | Critical — TPU stringing is severe |
| support.enable | false | Avoid supports for TPU — design around them |
| others.bed.brimType | Outer brim only | Light brim for TPU adhesion |
What nozzle size should I use for TPU 95A HF?
0.4mm — slower speed needed for fine flexible prints
0.4mm standard nozzle
0.6mm — larger nozzle improves TPU flow consistency
How do I dry TPU 95A HF filament?
Dry TPU 95A HF at 55°C for 4-6 hours. Moderate — dry if popping/bubbling occurs
What support material should I use with TPU 95A HF?
Recommended: Avoid supports — design parts to minimize overhangs
TPU supports are very difficult to remove. If unavoidable, use same material with minimal tree supports. PVA not compatible.
Expert Tips for TPU 95A HF
- TPU printing is ALL about speed — too fast and it buckles in the extruder.
- Disable retraction or use minimal retraction (0.5-1mm) to prevent jamming.
- Gyroid infill gives the best flex behavior — it compresses evenly.
- The H2D's direct drive extruder handles TPU much better than Bowden setups.
- If prints are stringy, reduce temperature by 5°C increments.
Which Bambu Lab printers work with TPU 95A HF?
Alternatives to TPU 95A HF
If you need a softer, more rubber-like flexibility for seals or grips
Trade-offs: Much harder to print — requires extremely slow speeds. Fewer color options
If the part doesn't truly need flexibility and you want easier printing
Trade-offs: No flexibility at all — rigid material. Cannot compress or bend
