ABS Filament

ABS is a strong, heat resistant 3D printer filament used for functional and mechanical parts. It holds its shape to around 100°C and can be sanded, glued and vapour smoothed. ABS needs a heated bed and an enclosure to avoid warping. We stock ABS in 1.75 mm on plastic spools, including carbon fibre, glass fibre and matte grades.

Types of ABS we stock

• Standard ABS and ABS V2 for general mechanical parts.
• ABS CF and ABS GF for stiffer parts that warp less.
• Matte ABS for a flat finish.
• Wood and marble ABS for effect prints.

What ABS is good for

ABS suits printer parts, automotive interior parts, housings and brackets that sit near heat. It machines and sands well and takes acetone smoothing. ABS gives off fumes while printing, so print it in an enclosure with ventilation or filtration. For outdoor parts ASA prints much the same and adds UV resistance.

Print settings

Keep draughts off the print and let the chamber warm up before you start. Free slicer profiles are available, and data sheets are in the TDS library.

Common questions

Does ABS need an enclosure?

ABS prints far more reliably in an enclosure. ABS shrinks as it cools, and cold air on the part causes warping and cracks between layers. An enclosed printer keeps the air warm and still, which lets larger ABS parts finish without lifting off the bed.

What temperature should I print ABS at?

ABS usually prints with the nozzle at 240 to 260°C and the bed at 90 to 110°C. Keep the part cooling fan off or very low. Higher chamber temperatures improve layer bonding and reduce warping on bigger ABS parts.

What is the difference between ABS and ASA?

ABS and ASA print on very similar settings and have similar strength and heat resistance. The main difference is that ASA resists UV light and weather, so ASA keeps its colour and strength outdoors. ABS yellows and turns brittle in long term sun.
