Acrylonitrile Butadiene Styrene (ABS)

Acrylonitrile butadiene styrene is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C. ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.

ABS is used to make light ,rigid, molded products such as pipe, automotive body parts , wheel covers, enclosures and protective head gear. 

ABS's light weight and ability to be injection molded and extruded make it useful in manufacturing products such as drain-waste-vent (DWV) pipe systems. Musical instruments such as recorders, plastic oboes and clarinets, piano movements, and keyboard keycaps are commonly made out of ABS^]

Other uses include golf club heads (because of its good shock absorbance), automotive trim components, automotive bumper bars, binoculars, inhalers, monocular, nebulizers, non-absorbable sutures, tendon prostheses, drug-delivery systems tracheal tubes, enclosures for electrical and electronic assemblies (such as computer cases), protective headgear, whitewater canoes, buffer edging for furniture and joinery panels, luggage and protective carrying cases, pen housing, and small kitchen appliances. Toys, including LEGO and Kre-O bricks, are a common application.

Household and consumer goods comprise the major applications of ABS.

ABS plastic ground down to an average diameter of less than 1 micrometer is used as the colorant in some tattoo inks.

When extruded into a filament, ABS plastic is a common material used in 3D printers.

When it is used as a filament for the 3D printing by fused deposition modeling, it is suitable due to the high stability and various post-processing options (sanding, painting, gluing, filling), especially for the production of prototypes.
