Bambu Lab PLA Sparkle Filament 1.75mm 1kg

PLA Sparkle blends fine metal particles into the filament, so every layer catches the light with a genuine sparkle rather than a printed-on glitter effect. Six colourways, from Classic Gold to Onyx Black, all carrying the same fleck-in-the-plastic shimmer.

Unlike some specialty finishes, Sparkle doesn't trade away much strength for the look — its mechanicals sit close to PLA Basic's. The metal content does mean steering clear of a 0.2mm nozzle, though; the particles are prone to clogging one that fine.

At a glance

Worth knowing

The sparkle comes from embedded metal particles, which is also why Bambu doesn't recommend a 0.2mm nozzle for this one — clogging risk. Stick to 0.4mm and up, same guidance as filaments with embedded fillers.

Mechanically it holds up well for a specialty finish — tensile and bending strength are in the same range as PLA Basic, so you're paying for the look rather than trading away toughness.

Storage

Bambu specifies under 20% RH, sealed with desiccant, and 55°C for 8 hours before printing. A sealed box with fresh desiccant does the job, or a filament dryer if you have one. Drop a cheap hygrometer in the box so you're not guessing.

As filament takes on moisture you'll hear popping or hissing at the nozzle, then see stringing and rough surfaces, and eventually the strand goes brittle enough to snap in the tube. That's almost always moisture, not technique. Dry it at 55°C for 8 hours and it usually comes back.
