Extrafill HiPS (Polystyrene)

Extrafill HiPS filament (Polystyrene) (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 impressions, although for the PLA is more recommended the PVA as support material. The filament Extrafill HiPS (Polystyrene) is a material resistant to heat and with physical properties ideal for use in the packaging industry, food, etc.

This filament has been approved as a valid filament for direct contact with food according to EU regulations (in the US, only the natural color is approved). To ensure that the final product meets the requirements, it must undergo testing in accordance with relevant regulations. These regulations define the testing conditions, which are based on the intended use of the printed object (e.g., temperature, duration of contact, type of food).

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 (Due to the high resolution printing) material. Extrafill HiPS filament (Polystyrene) is a bit lighter than the ABS. The temperature optimum print is 245 °C. When printed at this temperature it is necessary that the temperature of 90-100 ºC bed is to minimize the warping effect.

Besides the Extrafill HiPS filament has a very good seal so it is ideal for containing liquids without leakage. This property is due to the high thermal inertia of  own Extrafill HiPS which enables a very good adhesion between layers print.

Extrafill HiPS 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 you long exposure to the sun it discolor and become brittle. If you need a material that resists well UV light rays you must choose the ASA filament. HIPS (Polystyrene) has low electrical conductivity (10¹⁴ Ω*cm), which can be used as an electrical insulator. Its properties typically used in high-frequency. As for the softening temperature HIPS it supports up to 88 °C.
