Print Guide – Flexible and Rigid Filaments
1. Speed Recommendations
-
Direct Extrusion (Near-end):
-
With retraction: up to 50 mm/s
-
Without retraction: up to 60 mm/s
-
-
Bowden Extrusion (Distal):
-
Without "pumping back": up to 20 mm/s
-
Max. 30 mm/s without retraction
-
2. Slicer Settings
-
For high flexibility and softness:
-
Use no infill, and keep wall thickness between 0.8 mm and 1.2 mm for the best result.
-
-
For more elasticity and structure (stiffness):
-
Use 5–15% infill, and set wall thickness to ≥ 1.2 mm for increased stability.
-
3. Adjustment for larger prints
Flexible filaments have slower curing times. For larger models, you can gradually increase print speed up to 10 mm/s, depending on model size.
4. Limitations of flexible materials
-
Not suitable for hollow models or models with large overhangs, as the material does not effectively support these structures.
-
Not suitable for tall models, as top structures can cause nozzle snags and instability, which can lead to print failures.
