Poly(styrene-butadiene-styrene) is a hard, durable rubber that is commonly used for shoe soles, tires and other products that experience high wear. SBS is a copolymer, meaning that it is a mix of two different types of monomers. Copolymers allow manufacturers to combine the desirable properties of multiple polymers. An SBS polymer consists of a long chain of polybutadiene sandwiched between two chains of polystyrene. SBS belongs to the much larger family of plastics, the Thermoplastic Elastomers
Polystyrene is a very tough, hard plastic and is what gives SBS its excellent durability. Polybutadiene is a rubbery polymer and is what gives SBS its ability to retain its shape. SBS 3D prints are ideal for products that need to withstand a lot of wear and tear whilst also being tough and semi-flexible.
SBS has a glass transition temperature around 80°C and a printing temperature between 210°C and 230°C. SBS emits little to no odour when printing however you should still print in a very well ventilated area to avoid inhalation of ultrafine particles. SBS prints very smoothly with great adhesion and very low warp. SBS filaments tend to have a very constant diameter. SBS is available in solid colours as well as clear or transparent colours. One of the great advantages of SBS is that it can easily be smoothed as it is dissolved by D-Limonene solution to give a glassy, high quality finish.
If you're looking for a tough and very durable filament that can be very easily smoothed to give an attractive, glassy finish then SBS is a great option.
