PLA Silk+ Print Settings
Expert-recommended PLA Silk+ (PLA) settings for all Bambu Lab printers
Why use PLA Silk+?
- Stunning glossy, metallic-like surface finish
- Eye-catching shimmer effect without post-processing
- Available in brilliant gold, silver, copper, and multi-color options
- Great for decorative pieces, vases, and display models
- Easy to print — same temperature range as standard PLA
What are the best PLA Silk+ print settings?
Use default Bambu Lab temperature profiles for PLA Silk+. Recommended outer wall speed is 150 mm/s.
| Setting | Value | Note |
|---|---|---|
| speed.layers.outerWall | 150 | Slower outer walls maximize the silk sheen effect |
| speed.layers.topSurface | 150 | Slower top surface for even silk finish |
| quality.ironing.type | Top surface only | Ironing enhances the silk metallic effect on top surfaces |
| quality.seam.position | Back | Seams are highly visible on silk finish — hide them |
| quality.advanced.orderOfWalls | outer/inner | Outer-first gives better silk surface finish |
| support.filament.interface | Support for PLA (Bambu Lab) | Critical for silk — full support leaves highly visible marks |
| support.filament.base | Same as model | PLA Silk as bulk support |
What nozzle size should I use for PLA Silk+?
0.4mm nozzle — silk effect is best with standard nozzle
0.4mm standard — optimal for silk sheen
0.6mm nozzle — silk effect is slightly reduced but still visible
How do I dry PLA Silk+ filament?
Dry PLA Silk+ at 50°C for 4-6 hours. Low priority — PLA absorbs moisture slowly
What support material should I use with PLA Silk+?
Recommended: PLA Silk base + Support for PLA interface
Base: Same as model (PLA Silk) | Interface: Support for PLA (Bambu Lab)
Interface-only approach is critical for silk — full support contact leaves highly visible marks on the shiny surface. Breakaway interface minimizes contact area.
~25% less support filament used
Expert Tips for PLA Silk+
- Silk filaments are slightly more brittle than standard PLA — not ideal for functional parts.
- Ironing on top surfaces dramatically improves the metallic sheen.
- Print outer walls first (outer/inner) for the best surface appearance.
- Avoid supports touching visible surfaces — they leave marks on the shiny finish.
