What You'll Learn
ABS plastic is used in 3D printing
ABS plastic is a popular choice for 3D printing. It is a thermoplastic polymer made by mixing together two plastics and one rubber. ABS stands for Acrylonitrile Butadiene Styrene, and its properties depend on the ratio of the blend. Acrylonitrile provides rigidity and heat resistance, but too much will reduce elasticity. Butadiene is a synthetic rubber that creates stronger, more unsaturated hydrocarbon chains. Styrene gives the plastic a shiny, hard surface, while the polybutadiene provides toughness and ductility at low temperatures. Overall, the nitrile groups from neighbouring chains bind them together, making ABS stronger than polystyrene.
ABS is a good filament for general-purpose 3D printing. It is strong, easy to work with, affordable, and has good stability. It can be used to create functional prototypes or parts for end-use applications, such as toys, home appliances, car parts, and medical prostheses. ABS is also used in the automotive industry for tools and customising interior car components.
ABS is sensitive to temperature changes, which can cause the material to shrink or warp during the cooling process. Therefore, it is recommended to use a heated print bed at 110º C and an enclosure to prevent rapid temperature changes. ABS also tends to produce strong fumes or smoke during the manufacturing process, so proper ventilation or a fume extractor is necessary.
ABS plastic has a low melting point compared to other plastics and is not suitable for high-temperature situations. It also has poor resistance to UV light, solvents, and fatigue stress. However, it can be post-processed in various ways, including sanding, painting, gluing, filling, and chemical smoothing with acetone to achieve a glossy finish.
In summary, ABS plastic is a popular choice for 3D printing due to its strength, durability, heat resistance, and low cost. However, it requires careful temperature control and ventilation due to its sensitivity to temperature changes and fumes.

ABS is recyclable
ABS plastic, or Acrylonitrile Butadiene Styrene, is indeed recyclable. It is a thermoplastic polymer, which means it can be melted and reshaped multiple times without losing its properties. This makes ABS very conducive to being recycled. The temperatures required to melt solidified ABS are easily achievable, even on a domestic scale. This is one of the reasons why ABS is a popular consumer-grade 3D printing filament. ABS is also relatively inert, resulting in its almost ubiquitous use in products ranging from car dashboards and steering wheel covers to children’s toys, keyboard keycaps, and plastic guards on power outlets.
The recycling process for ABS is similar to other rigid plastics and is facilitated by its easy melting. Recycled ABS input can be mixed with virgin resin in the manufacturing of new products while retaining product quality. ABS is not conventionally recycled through street-collection programs and does not have its own unique resin identification number. However, some companies provide ABS recycling services for businesses looking to reduce their environmental impact. The process usually involves inspecting the material for quality and weighing it to ensure accurate environmental reporting. The next stage is shredding the material and passing it through a granulator, after which it can be used within the injection moulding process.
ABS is heavily utilised in various industries because of its high-impact resistance and ability to withstand tough conditions. From automotive parts to products produced through injection moulding, the potential applications of ABS are nearly limitless. Recycling ABS reduces the need for virgin plastic production, thus conserving valuable non-renewable resources, reducing energy consumption, and cutting down greenhouse gas emissions.
ABS is derived from acrylonitrile, butadiene, and styrene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene, and 40% to 60% styrene. The result is a long chain of polybutadiene crisscrossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighbouring chains attract each other and bind the chains together, making ABS stronger than pure polystyrene. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The butadiene, a rubbery substance, provides toughness and ductility at low temperatures, at the cost of heat resistance and rigidity.

ABS is resistant to corrosion and chemicals
Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic polymer known for its strength, durability, and versatility. It is a hard plastic that remains durable at temperatures as low as -40°C. ABS has a high resistance to temperature fluctuations and demonstrates good heat resistance. It is also highly impact-resistant.
However, ABS is swollen by glacial acetic acid, carbon tetrachloride, and aromatic hydrocarbons and is attacked by concentrated sulfuric and nitric acids. It is soluble in esters, ketones (such as acetone), chloroform, and ethylene dichloride. ABS also offers poor resistance to chlorinated solvents, alcohols, and UV light.
Despite these limitations, ABS remains a popular choice for manufacturing due to its strength, ease of use, affordability, and ability to be recycled. It can be found in a wide range of products, from toys and home appliances to car parts and 3D printing applications.
