High Impact Polystyrene or HIPS is one of the existing varieties within polystyrenes. Since polystyrene is a very fragile polymer at room temperature, it is modified by the addition of polybutadiene to improve its resistance to impact.
Premium HIPS Filament (High Impact Polystyrene) is a thermoplastic obtained by polymerizing high impact resistance. It is known as "High Impact Polystyrene" and used as support material ABS or PLA prints.
Although most of its mechanical and physical properties (stiffness, tensile strength and impact resistance, thermal stability, ...) are similar to those of ABS, there is a feature that makes it different to everyone else which is its solubility in D-Limonene, allowing to make unworkable forms a soluble support material and will be realized once the piece in D-Limonene and HIPS immerse disappears, leaving the piece without any support material with a high surface quality.
It is indicated for light and high quality technical parts material. Premium HIPS filament is a bit lighter than the ABS, which is why it can be printed at a temperature slightly lower. The temperature is 230C optimal printing. When printed at this temperature it is necessary that the temperature of 90-110 bed is to minimize the warping effect.
Premium HIPS (Polystyrene) filament is resistant to oils, fats and alkalis but not fuel. As for his post-processing and finishing it can be chrome, paint, glue and sand. HIPS supports evil UV rays, so long exposure to sun fade and become brittle him. It has low electrical conductivity, so it can be used as insulation. Its properties typically used in high-frequency. As for the softening temperature HIPS supports up 95ºC.

It´s a material with properties very similar to those of ABS that printing is not especially difficult to print. Nozzle temperature should be between 230 and 235 °C. As in the case of ABS, the need to use a hot bed at a temperature of about 110 °C. Once the printing must wait for the piece cool before removing to prevent any deformation may occur due to the printing temperature.
