Filament finder

Which filament do you need? Answer two quick questions and we'll point you to the right material, the filament we sell for it, and whether it suits your printer.

1. What are you printing?

2. Which printer do you have? (optional)

Pick an answer above, or read through every suggestion below.

Every suggestion

Indoor models, toys and decorations: PLA

For: models, toys and decorations · Material: PLA

PLA is the easiest filament to print, comes in the widest range of colours and finishes, and warps very little. Bambu Lab calls PLA the default filament for most 3D printers.

Your printer

Any printer will do. For a first printer, look at the A1 mini or A1. Compare Bambu Lab printers.

  • Keep PLA away from damp air. Bambu Lab recommends drying it before use if you're not sure how it has been stored.

New to 3D printing: start with PLA

For: i'm new to 3d printing · Material: PLA

Bambu Lab's beginner advice is to start with PLA and only move to other materials once you're confident. It prints at lower temperatures and gives predictable results.

Your printer

The A1 mini and A1 are Bambu Lab's entry printers: quiet, set themselves up, and print PLA, PETG and TPU. Compare Bambu Lab printers.

  • Not sure about refills? A refill is the filament without the plastic spool – it fits onto a Bambu reusable spool you already own.

Special finishes: silk, matte, marble, sparkle and more

For: something that looks special · Material: PLA with a special finish

Most special finishes are PLA, so they print as easily as normal PLA. Pick the look first – a finish changes how a print looks, not how strong it is.

Filament we sell for this

Your printer

Any printer will do. For several colours in one print, choose a Combo with an AMS. Compare Bambu Lab printers.

  • Bambu Lab says PLA Wood must be dried before use, and it doesn't work with a 0.2 mm nozzle.
  • For many colours in one print you need an AMS. See which AMS fits your printer.

Strong, practical parts: PETG, PLA Tough+ or carbon fibre

For: strong, practical parts · Material: PETG (or PLA Tough+, PLA-CF, PETG-CF)

Bambu Lab rates PETG higher than PLA for strength and durability, and it's still easy to print. For stiff parts, carbon-fibre filled filaments are an option – they need a hardened steel nozzle.

Filament we sell for this

Your printer

Any printer prints PETG. If you also want carbon-fibre filaments without changing parts, the P2S and H series come with hardened steel nozzles. Compare Bambu Lab printers.

  • PETG absorbs moisture more than PLA. Keep it sealed and dry it before use for the best finish.

Outdoor parts: ASA or PETG

For: outdoors (sun and rain) · Material: ASA (or PETG)

Bambu Lab describes its ASA as having excellent UV and weather resistance, ideal for outdoor parts. ASA needs an enclosed printer. On an open-frame printer, Bambu Lab's PETG Basic is the alternative: it has improved resistance to water, UV and temperature.

Filament we sell for this

  • Bambu Lab ASA£21.99UV and weather resistant. Enclosed printer required; not for AMS lite.
  • Bambu Lab PETG Basicfrom £15.99Suggested by Bambu Lab for outdoor accessories.

Your printer

For ASA choose an enclosed printer: P2S, P1S or the H series. Any printer can do PETG. Compare Bambu Lab printers.

  • ASA comes on a high-temperature reusable spool. Bambu Lab lists ASA as not compatible with AMS 2 Pro drying – use an AMS HT or the printer's heated bed.

Heat resistant parts: ASA or ABS

For: heat resistant · Material: ASA or ABS

ABS and ASA cope with heat much better than PLA. Bambu Lab gives a heat deflection temperature (a lab test) of 100 °C for its ASA and 87 °C for its ABS. Both need an enclosed printer.

Filament we sell for this

  • Bambu Lab ASA£21.99HDT 100 °C (Bambu Lab figure), also UV resistant.
  • Bambu Lab ABSfrom £15.99HDT 87 °C (Bambu Lab figure), tough and durable.

Your printer

Choose an enclosed printer: P2S, P1S or the H series. For nylon and PC, Bambu Lab's H series is the best fit. Compare Bambu Lab printers.

  • ABS and ASA give off fumes while printing: use an enclosed printer with a filter, in a ventilated room.
  • Neither works in the AMS lite.

Flexible parts: TPU for AMS

For: flexible or rubbery · Material: TPU

TPU bends instead of snapping. Ordinary TPU is too soft to feed reliably through an AMS, so Bambu Lab makes TPU for AMS (Shore 68D) that works in all AMS units, including the AMS lite.

Filament we sell for this

Your printer

Any printer will do. The H3C's FlexFeed extruder also takes 2.85 mm TPU for very soft grades. Compare Bambu Lab printers.

  • TPU must be dried before use (Bambu Lab). The AMS 2 Pro may not dry TPU fully – use an AMS HT or the printer's heated bed.

Supports that come away cleanly

For: easy-remove or soluble supports · Material: Support material or PVA

Support materials are used only for the layers that touch your model, so supports come away cleanly and leave a smoother surface. PVA dissolves in water.

Filament we sell for this

Your printer

You need an AMS (or two nozzles) to print support material with your model. The H2D, H2C and H3C cut purge waste the most. Compare Bambu Lab printers.

  • Damp PVA can jam in the AMS – dry it first. Bambu Lab lists PVA as not compatible with AMS 2 Pro drying; use an AMS HT (85 °C).
