Hello I am planning on making a paste extruder to use for support structures. Any good ideas for a good stiff paste that would disolve in water? I've thought about using clay, or frosting. The problem with clay is it is hard to get to a good consistancy and keep it there. Most frosting recipies call for dairy products and eggs or shortening. I don't want something that will spoil or get my printer all greasy. I am planning on coating the inside parts of the extruder with the type of enamel that is used on stove tops and refrigerators to give it a food safe seal and smooth surface.
