Bambu Lab PLA Marble

Bambu Lab PLA Marble 1.75 mm — Stone-Effect Filament

PLA Marble is a standard-temperature PLA blended with fine inorganic mineral particles. Those particles break up the surface as the filament extrudes, giving finished prints a speckled, matte, stone-like texture that reads as marble, granite or aged brick — and, usefully for beginners, disguises layer lines and small surface defects that would show on a glossy filament. It behaves like the PLA you already know: low warp, no enclosure needed, no heated chamber, and it prints happily on an open-frame machine in a spare room or classroom.

It suits anyone who wants a finished-looking part without a paint booth: architectural models and terrain, vases, planters and pen pots, chess sets and board-game pieces, busts and statuettes, lamp bases, coasters, and props or display pieces that need to look like carved stone. Schools and makerspaces like it because a single spool turns basic geometry into something students are proud to take home. It's a decorative filament rather than a structural one — for load-bearing or outdoor parts, step up to PETG or ASA.

Print Settings

• Nozzle temperature: 190–230°C (around 220°C is a good starting point)
• Bed temperature: 35–45°C
• Print speed: up to 250 mm/s — drop to 60–100 mm/s on fine detail for the crispest texture
• Cooling: part cooling fan on (100% for most decorative prints)
• Nozzle size: 0.4, 0.6 or 0.8 mm — a hardened steel 0.4 mm nozzle is recommended, as the mineral particles are mildly abrasive. Avoid 0.2 mm nozzles: they clog.
• Retraction: 0.6–1.0 mm at 20–40 mm/s
• Build plate: Cool Plate, Textured PEI Plate or High Temperature Plate
• Drying (if needed): 55°C for 8 hours

Specifications

Available Colours

White Marble (13103)
Red Granite (13201)

Choose your finish from the Colour dropdown above. Both colours share identical specs and print settings, so you can swap between them mid-project without retuning your profile.

Compatibility

Works with any 1.75 mm FDM printer — Bambu Lab X1, P1, H2 and A1 series (RFID-tagged for AMS auto-recognition), plus Prusa, Creality, Elegoo, Anycubic and most open-frame machines. No enclosure or heated chamber required.

Practical Tips

Let the texture do the work. The stone effect is strongest at 0.2 mm layer height or thicker, and looks best on large, simple surfaces — vases, plinths, planters — rather than tiny detailed miniatures where the speckle can muddy fine features. Sanding removes the effect, so print it as-is; if you want a polished stone look instead, a light dry-brush of wax or a matte clear coat deepens the contrast without filling the grain.

Nozzle and storage. The mineral fill is mildly abrasive, so a hardened steel nozzle will outlast brass by a wide margin — and skip 0.2 mm nozzles entirely to avoid clogs. Like all PLA it picks up moisture from humid Australian air, so reseal the spool in its bag with desiccant between jobs; if you get stringing or a rougher-than-usual surface, dry at 55°C for 8 hours before printing.
