Recommended Settings
| Item | Recommended Value | Notes |
|---|---|---|
| Nozzle Temperature | 220-250°C | Lower temp for transparency |
| Bed Temperature | 70-80°C | For better adhesion |
| Fan Setting | 30-50% | Too strong causes poor layer adhesion |
| Print Speed | 30-50mm/s | Slow speed prevents stringing |
| Nozzle Diameter | 0.4-0.6mm | 0.6mm reduces stringing |
| Caution | Prone to stringing, retraction adjustment required | |

| Item | Measured Value |
|---|---|
| Default (Flat Layout) | |
| Bending Strength | 76.69 MPa |
| Flexural Modulus | 2033 MPa |
| Z-Axis Strength (Vertical Layout) | |
| Bending Strength | 26.59 MPa |
| Flexural Modulus | 1703 MPa |
