HIPS - Dissolving Filament for use with ABS

2.2lb (1kg) rolls of HIPS (High Impact PolyStyrene). HIPS can be printed along with ABS and then dissolved away using a chemical called Limonene which is common in many household cleaners. Using this as support with dual extruders can allow allow you to print far more complicated models and parts that were unprintable before. The two plastics print really well together but the HIPS portion can also be torn away cleanly after it has cooled or completely dissolved.
