The stickiness and extreme plasticity of Polar Ice porcelain has enabled many people to use it for 3D Printing. This is a piece being done by Bryan Cera. Polar Ice in plastic form is better than Polar Ice for casting because the former contains much more Veegum. Layers adhere well and pieces can hold up even though the clay may be very soft. We manufacture it in soft form, although it may feel very stiff in the box, open wedging the clay softens markedly and might be suitable if you have a 3D printer that can handle stiffer paste (of course, if the clay is getting old it will be stiffer). The Veegum in Polar Ice slows drying and increases drying shrinkage - be judicious about how fans are set (they should expose all sides to draft). Printing on a piece of plaster is also advisable (it will draw water from the base). If the plastic version of Polar Ice is just too stiff then you might consider mixing the printing paste from the casting version. It will not be as plastic but will dry faster. Adding Veegum will improve its plasticity (but beware of how difficult it can be to slurry up a body containing a lot of it). If you cannot get this body then just make your own using the L3778D recipe.
Clay for 3D printing. People are getting carried away with the technology and forgetting the common sense things relating to the clay.
