Bambu Lab ABS

Bambu Lab ABS Filament — 1.75 mm, 1 kg

ABS (acrylonitrile butadiene styrene) is the classic engineering thermoplastic — the same material used for power tool housings, automotive trim and LEGO bricks. Compared with PLA it takes far more heat and absorbs impact instead of shattering, which makes it the right pick when a printed part has to be used rather than displayed. Bambu Lab's ABS pairs that toughness with tight diameter control and RFID spool recognition, so you spend your time printing instead of dialling in profiles.

It suits makers and small businesses printing functional prototypes, jigs and fixtures, brackets and enclosures, RC and drone parts, tool holders, replacement appliance and automotive clips, and anything destined for a workshop or a sunny car interior. Schools and beginners stepping up from PLA will find it rewarding, with one honest caveat: ABS wants a stable, warm environment, so an enclosed printer makes the difference between a frustrating print and a great one.

Key features

High impact resistance ~94 °C softening temp ±0.03 mm tolerance AMS compatible RFID auto-recognition Sandable & glueable Reusable spool Up to 300 mm/s

• Built for function. Tough, rigid and impact-absorbing, with far better heat tolerance than PLA or PETG.
• Finishes beautifully. ABS sands, drills, taps and solvent-welds cleanly, and takes paint well — ideal for parts you want to post-process.
• Consistent feeding. A ±0.03 mm diameter tolerance means fewer under- and over-extrusion surprises on long prints.
• Hands-off setup. The RFID tag tells a Bambu Lab printer exactly what is loaded, including through the AMS for multi-colour and multi-material work.
• Works with any 1.75 mm FDM printer that has a heated bed and can reach 270 °C — best results in enclosed machines such as the X1 series, P1S or H2D.

Recommended print settings

• Nozzle temperature: 240–270 °C — start at 260 °C and adjust for layer adhesion
• Bed temperature: 80–100 °C — a smooth PEI plate plus glue stick gives the most reliable grip
• Chamber temperature: 45–60 °C — keep the enclosure shut and the door closed for the whole print
• Print speed: under 300 mm/s; slow the outer walls and first layer for the best surface and adhesion
• Part cooling fan: 0–80% — keep it low. Too much airflow is the single most common cause of warping and layer splits in ABS
• Drying: 80 °C for 8 hours if the spool has been open a while; store sealed below 20% RH

Practical tips

Warping is a draught problem, not a filament problem. ABS shrinks as it cools, so uneven cooling pulls corners off the plate. Keep the enclosure closed, run the part cooling fan low (0–30% for most geometry), add a brim on tall or thin-footed parts, and let the bed come fully up to temperature before the first layer goes down. If you are printing on an open-frame machine, a simple cardboard or acrylic shroud around the printer makes a bigger difference than any slicer tweak.

Keep it dry and print it in a ventilated space. ABS picks up moisture more slowly than nylon or TPU, but a damp spool still shows up as popping sounds, rough walls and weak layers — dry at 80 °C for 8 hours and store the spool sealed with desiccant between jobs. ABS also gives off a noticeable odour while printing, so run it in a ventilated room or use a printer with filtered exhaust, especially in a classroom or home office.
