Bambu Lab PLA Galaxy

Bambu Lab PLA Galaxy Filament — 1.75 mm, 1 kg

PLA Galaxy is Bambu Lab's take on a starfield finish. Fine glass microspheres are blended through a standard PLA base, acting as tiny internal reflectors that scatter light across the print surface. The result is a glossy, softly glittering look that reads as depth rather than glitter-dust — and because the base polymer is ordinary PLA, it prints as easily as the PLA Basic you already know. That makes it a sensible pick for makers who want a display-grade finish without moving to a fussy engineering material: tabletop miniatures and terrain, cosplay props and jewellery, planters and vases, awards and gifts, product mock-ups, and classroom projects where the finished part needs to impress.

Key features

Glass microsphere sparkle Glossy finish, no polishing Prints like standard PLA Up to 250 mm/s RFID auto-settings AMS & AMS lite ready 1.75 mm ± 0.03 mm Reusable 1 kg spool

The spool carries an RFID tag, so a Bambu Lab printer with AMS or AMS lite recognises the material and loads the correct profile automatically. On non-Bambu machines — Prusa, Creality, Elegoo, Anycubic, Voron and most other 1.75 mm FDM printers — simply start from your generic PLA profile and apply the temperatures below.

Print settings

• Nozzle temperature: 190–230 °C — start at 220 °C and tune for gloss
• Bed temperature: 35–45 °C (textured PEI; use glue stick on smooth plates)
• Print speed: up to 250 mm/s — slower outer walls (around 60–100 mm/s) give the most even sparkle
• Part cooling: 100% fan, as with any PLA
• Chamber: not required — keep enclosed printers vented to avoid heat creep
• Nozzle: hardened steel 0.4, 0.6 or 0.8 mm recommended; 0.2 mm nozzles are not suitable
• Drying (if needed): 55 °C for 8 hours in a blast drying oven or filament dryer

Tips from our workshop

Let the light do the work. The sparkle comes from microspheres sitting just under the surface, so it shows best on curved geometry, gentle chamfers and vase-mode prints. Flat top surfaces printed with a wide, fast infill pattern can look duller — try ironing off and a slower outer wall speed if the finish looks patchy between layers.

Mind the nozzle, and mind the moisture. Glass microspheres are mildly abrasive, so fit a hardened steel nozzle before a long print — a brass nozzle will wear and start under-extruding. Like all PLA, Galaxy absorbs moisture from the air: reseal it in the bag with desiccant between sessions, and if you hear popping or see stringing after a humid Australian summer, run it at 55 °C for 8 hours in a dryer before printing.
