Clay Printer / Nozzle Clogged

What to do if the clay 3D printer nozzle is clogged?

    Pause printing and turn off the power, then remove the nozzle. Clean clay residues with a stiff brush and warm water (avoid sharp tools to scratch the nozzle). For hard residues, soak the nozzle in 30-40℃ warm water for 10 minutes before cleaning. After reinstallation, calibrate the nozzle-platform gap and extrude a small amount of clay idly before printing to prevent re-clogging

Important: Never use metal needles, drills or other sharp objects to poke the nozzle — this can easily damage the inner wall or opening and cause permanent clogging or poor extrusion.

Clay Printer / Layer Separation & Non-Adhesion

How to solve layer separation and non-adhesion with clay 3D printers?

    Focus on clay moisture content (18%-22% recommended) and extrusion volume: add water if too dry, mix with dry clay powder if too wet. Adjust extrusion multiplier to 108%-110% and printing speed to 20-30mm/s. Compact clay in the hopper without air gaps, and slow the first layer speed by 5mm/s to enhance adhesion.

Important: Layer separation is most commonly caused by incorrect moisture content or air pockets in the hopper. Always check and adjust clay consistency before starting a print.
