ABS
ABS filament — properties and applications
ABS (acrylonitrile butadiene styrene) is an engineering plastic with good heat and impact resistance, widely used in automotive and industrial applications.
Key properties
- Typical printing temperature 240–260 °C, bed 90–110 °C.
- Heat resistance around 90–100 °C.
- High impact resistance and toughness.
- High warping tendency; an enclosed chamber is recommended.
- Can be smoothed with acetone vapour.
Use cases
- Automotive interior/exterior parts and holders
- Electrical device housings
- Mechanical brackets and assembly parts
- Functional parts exposed to heat
Advantages
- High heat and impact resistance
- An economical engineering plastic
- Surface finishing and bonding with acetone
Limitations
- Strong odour and fumes; ventilation is required
- High risk of warping and layer separation
- Needs an enclosed chamber or heated room
Frequently asked questions
Is an enclosed printer required for ABS?
An enclosed chamber keeps the ambient temperature stable and reduces warping and layer separation; it is recommended for reliable results.
Why does ABS smell?
Printing releases styrene fumes. It should be printed in a ventilated area or an enclosed, filtered printer.
Is ABS food-safe?
General-purpose filaments are not food-approved; food contact requires a certified product.
