HIPS, short for High Impact Polystyrene, is a rigid plastic comparable to ABS. These pellets can be used to produce HIPS filament for a finished object, or it could be used as a dissoluble filament for support material, when breakaway supports do not work. HIPS dissolves in d-Limonene, found here. The good thing about d-Limonene is that it is biodegradable, natural, and leaves your parts smelling like oranges.
