One idea for a support filler extruder would be to use a supersaturated solution of sodium acetate, which crystallizes very fast on shock.
One advantage would be easy removal, since soaking the finished object in hot water would dissolve the acetate very fast. The disadvantage is that it is extruded as a liquid, making it hard to control, and that it must be kept heated from the container to leaving the toolhead.
