High Impact Polystyrene (HIPS) is a tough, rigid plastic material with high impact strength which can be guillotined, punched, routered or sawn easily, and is readily available in a wide variety of colors. Used widely for toys, packaging, signs, kicking plates, display and point of sale.
Some people choose to print with HIPS by itself but the real magic of this filament is if you have a dual extruder and you use it as a dissolvable support material.
HIPS is as easy to print with as ABS but is much less likely to warp. HIPS is ideal for printing in conjunction with ABS because it has a similar strength and stiffness profile to ABS which means they complement each other well. HIPS prints best with the bed at 55°C and the extrusion temp around 225°C.
Pros: Impact & water resistant, Dissolvable by L-Limonene
Cons: High printing temp, Ventilation required
