3. Workflow
Drying and Storage |
|
Note: PEBA is highly hygroscopic, meaning it readily absorbs moisture from the air. Wet filament leads to poor print quality (stringing, bubbling, weak parts, clogging). |

Bed Temperature |
60-100Β°C |
100Β°C for full plate large model print to prevent warping |
First Layer |
Print the first layer slower (e.g., 15-20mm/s) and slightly hotter (e.g., +5Β°C on nozzle) for best adhesion. Ensure proper nozzle height (z-offset). |
|
Cooling Fan Speed |
Use moderate part cooling (e.g., 70-100%) |
Too much cooling can weaken layer adhesion; too little can worsen overhangs and stringing. Start low and increase if needed |
Print Speed |
30-120mm/s |
PEBA can often be printed faster than TPUs at the same hardness level. Start conservatively (e.g., 40-60mm/s) and increase speed gradually while monitoring print quality. Reduce speed for complex geometries or fine details |
Retraction |
PEBA generally requires minimal retraction to prevent clogging and stringing. Start with low values of 0.4mm |

Parameter |
Recommendation |
Flow Rate / Extrusion Mult. |
Calibrate for optimal results. PEBA often requires a slightly lower flow rate (e.g., 93-96%) than rigid filaments. Print a calibration cube or object to check dimensions and extrusion quality. |
