BIGREP ABS

Compatibility:

BigRep’s ABS material is a classic FFF filament that enables the production of a wide variety of products in large-format additive manufacturing. A familiar automotive manufacturing material now specialized for industrial AM, BigRep ABS is a high-strength filament suitable for mobility and a variety of white-goods and consumer appliances.

BigRep ABS has been optimized for large-format additive manufacturing and is able to print complex, ready-to-use parts including end-use, factory tooling and functional prototypes with demanding geometries.

Highlights:

• High impact strength
• Easy post-processing
• Excellent adhesion
• Minimal warping
• High heat resistance

Hands-on Review

ABS has superior impact resistance so it’s commonly found in automotive applications. It’s good in the heat too, with a heat deflection temperature of 195°F. And with a tensile strength of 30MPa, it’s strong enough for many end-use applications. ABS prints at a higher temperature than most materials and an enclosed build chamber is recommended to prevent warping, making it a bit more difficult to print than something like PLA.
