A stone filament
Laybrick is a mixture of milled chalk and harmless copolyesters. It has the visual characteristics of sandstone. It can be worked on further with a saw and sander, and the surface can be painted.
The printing temperature can range from around 165 degrees Celsius for a smooth surface to 245 degrees Celsius for a rough surface. It prints well on aluminum, acrylic, glass, and tape, and it doesn't require a heat bed. Caution is advised with regard to the surface bond of the material. It may be difficult to remove the print from the printbed surface without damage.
The material has negligible warping tendencies.
Printing with a cooling fan is recommended. It requires hardening time after printing. The object should be removed from the build platform 2-4 hours after printing.
Laybrick should be used in a well-ventilated area. It contains copolyesters, so it's capable of releasing small amounts of fumes at high temperatures.
