Clay 3D Printer FAQ
After printing, let the green body air-dry at room temperature for 2–4 hours to drain excess moisture, then dry it in a constant temperature oven at 30–40°C for 8–12 hours with a heating rate no faster than 5°C/hour. Avoid direct sunlight or rapid airflow to prevent cracking before trimming or bisque firing.
Suitable materials include high-plasticity clay (e.g., Dehua kaolin clay), porcelain clay, and clay slurries mixed with 10–15% organic binders. Maintain a moisture content of 25–30% and a viscosity of 6000–10000 mPa•s, and avoid large impurities to prevent nozzle clogging.
First, set the layer height to 0.2–0.3mm and the extrusion speed to 30–40mm/s to reduce layer lines. After printing, lightly sand the surface with 800–1200 grit sandpaper and polish it with a damp sponge; for fine textured areas, use ceramic-specific polishing paste for further treatment.
