1. Material Preparation & Parameter Settings
Clay Preprocessing
- Use manufacturer-recommended clay (e.g., porcelain clay, purple sand clay) with moisture content 18%-22%. Adjust viscosity by adding water or desiccant—ensure it’s extrudable (aggregate size ≤1mm for 1.5mm nozzles).
- Cut clay into small pieces, fill the hopper, and connect the feeding tube to the nozzle (check for no clogs).
Key Parameter Recommendations
| Parameter | First Test Setting | Reason |
|---|---|---|
| Layer Height | 0.3-0.5mm (0.2-0.3x nozzle diameter) | Prevents collapse from overly thick layers |
| Print Speed | 20-40mm/s (gradually up to 80mm/s) | Ensures uniform extrusion |
| Extrusion Multiplier | 105%-110% | Improves layer adhesion |
| Retraction Distance | 2-5mm | Avoids clay dripping during nozzle movement |
