Bambu Lab PLA Silk+ Filament — 1.75 mm, 1 kg

PLA Silk+ is standard PLA blended with pearlescent additives, which is what gives it that distinctive reflective, silk-like sheen. It prints as easily as regular PLA — no enclosure, no heated chamber, no hardened nozzle on a standard 0.4 mm hotend — but the finished part looks like it has been polished or anodised. That makes it a favourite for display models, cosplay props, figurines and busts, decorative vases, trophies, jewellery and giftware, and anything destined for a shelf rather than a load-bearing bracket.

It suits makers at any level. Beginners get a forgiving PLA that produces an impressive result on the first attempt; enthusiasts, schools and small businesses get a reliable, RFID-tagged spool that drops straight into an AMS for multi-colour work. The “+” designation is Bambu Lab’s upgraded silk formulation, with improved gloss consistency and layer adhesion over the original PLA Silk.

Key Features

Works with Bambu Lab X1 series, P1 series, A1 and A1 mini, and with most other 1.75 mm FDM printers — Prusa, Creality Ender and K-series, Elegoo, Anycubic, Sovol and similar. Note that Bambu Lab does not recommend PLA Silk+ with 0.6 mm or 0.8 mm hardened steel nozzles, and the Cool Plate SuperTack is not a recommended build surface for this material.

Recommended Print Settings

• Nozzle temperature: 210–240 °C. Run at the upper end (230–240 °C) for maximum gloss — hotter material flows and spreads more evenly, which is exactly what a silk finish depends on.
• Bed temperature: 35–45 °C, with glue stick on the plate.
• Print speed: up to 250 mm/s overall, but slow the outer wall to 30–60 mm/s (50 mm/s is a good default) for the best shine.
• Cooling: keep the part fan at a constant speed. Enable “Don’t slow down outer walls” in Bambu Studio — patchy gloss on silk prints is almost always the slicer varying speed or fan mid-print, not the filament.
• Drying: 55 °C for 8 hours if the spool has been left open.
• Nozzle: standard 0.4 mm stainless steel is fine — no hardened nozzle needed.

Tips From Our Workshop

Keep it dry. Silk PLA picks up moisture from the air faster than plain PLA, and damp filament is the number one cause of stringing and dull, uneven patches on an otherwise good print. In humid parts of Australia — Brisbane, Darwin, coastal NSW — reseal the spool in its bag with desiccant between jobs, or park it in a dry box. If a spool has been sitting out and the gloss has gone flat, dry it at 55 °C for 8 hours and it will come back.

Design for the shine. Silk highlights broad, gently curved surfaces beautifully, but it also exaggerates layer lines on steep overhangs and shallow angles. Orient display models so the show face is vertical or gently sloped, use a 0.16–0.20 mm layer height, and keep the outer wall speed constant. One more thing worth knowing: the pearlescent additives make PLA Silk+ slightly more brittle and less stiff than PLA Basic, so reach for it when appearance matters and choose PLA Basic, PETG or PLA-CF for functional and load-bearing parts.
