A ceramic filament
LAYCeramic is an experimental filament that is a blend of ceramic powder and polymers. After printing, the object can be fired to a hard ceramic by heating it up to 1200 degrees Celsius in a kiln. The resulting product can then be fired with decorative glazes.
The printing temperature can range from around 250-280 degrees Celsius.
Special modifications should be made. A full metal hot end is required, and a hardened, steel-hobbed bolt is needed for the extruder drive. It's recommended that you preheat the filament from 35 to 40 degrees Celsius in a flexible tube before it reaches the extruder.
Printing with a cooling fan is recommended.
LAYCeramic should be used in a well-ventilated area. It contains polymer binders, so it's capable of releasing small amounts of fumes at high temperatures.
