Bambu Lab PLA Silk+ Filament 1.75mm 1kg

Same easy PLA underneath, but with a silk gloss finish that catches light instead of scattering it. Bambu PLA Silk+ trades a little of Basic's toughness for a genuinely metallic-looking shine, in a colour range built around jewel tones and metallics rather than flat solids.

Good for anything meant to look good on a shelf — vases, ornaments, gifts, display pieces. It's noticeably shinier than any coating or paint job you'd add after the fact.

At a glance

Spool or Refill?

Spool — Comes on a reusable Bambu spool. Pick this for your first roll of a colour.

Refill — Filament only, $2 cheaper, needs an empty reusable spool to mount on.

Worth knowing

The shine comes at a small cost: Silk+ is softer and less rigid than Basic (lower Young's modulus), so it's a better fit for decorative pieces than load-bearing ones. Bending strength holds up well, so it's not fragile — just not the one to reach for on a structural part.

The silk finish actually works in your favour on layer lines — the way it catches and reflects light makes them read as far more subtle than on a matte or standard surface. It doesn't hold fingerprints the way a glossy coating would either; the sheen comes from the filament itself, and provides a lasting shine.

Storage

Bambu specifies under 20% RH, sealed with desiccant. A sealed box with fresh desiccant does the job, or a filament dryer if you have one.

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.
