Gold Silk PLA for Bambu Lab Printers: What to Choose

Bambu Lab is best known for fast, easy-to-run 3D printers, and its filament range is built to feed those machines with as little fuss as possible. Silk PLA is one of the most popular materials in that world because it turns an ordinary plastic print into something that looks polished, shiny and almost metallic. Gold is the color people reach for most when they want a print to feel like a gift: a trophy, a vase, an ornament or a nameplate that catches the light.
The three spools below all carry the same color name, Gold 13405, and all are 1kg rolls of 1.75mm silk PLA, but only the first is sold under the BambuLab brand; the other two are third-party spools from 3DTOOLS and TEWIRROW that use the word “Bamboo” in their titles and add an RFID tag so they work smoothly with the Bambu Lab AMS feeder.

Bambu Lab PLA Silk+ Filament 1.75mm
Best for: Buyers who want the Bambu Lab-branded spool
Pros
- Sold under the BambuLab brand
- 75mm with ±0.03mm tolerance
- Vacuum-sealed with desiccant
- Low warp, beginner friendly
Cons
- Listing does not mention RFID
- Feature text mixes in PLA Basic wording
The Bambu Lab PLA Silk+ Filament 1.75mm is the only spool in this list whose listing names BambuLab as both brand and manufacturer. It is a 1kg (2.2 lb) roll of polylactic acid, the plant-based plastic most beginners start with, in the Gold (13405) color. The listing promises a silk-like texture with metallic gold coloring, a smooth glossy finish, low warping, strong layer adhesion and a low-odor formula that makes printing at home more pleasant.
Two details matter for new makers. First, the diameter is held to 1.75mm with a tolerance of ±0.03mm, which means the strand stays very close to the size your printer expects, so it is less likely to jam or under-extrude. Second, each spool arrives vacuum-sealed with a desiccant pack. PLA slowly absorbs moisture from the air, and wet filament can print with bubbles, stringing and a duller surface, so a sealed spool gives you the best chance of a shiny first print. The listing says it works with Bambu Lab printers and most other FDM printers, which is handy if the spool is a gift and you are not sure which machine the recipient owns.
Be aware that the listing is a little messy. One feature bullet describes “PLA Basic filament” even though the product is PLA Silk+, and the item weight is given as 2.9 pounds while the spool itself is described as 1kg (2.2 lb), so the extra weight is probably the spool and packaging, though the listing does not say. The listing also does not mention an RFID tag, so if automatic AMS setup is the priority, the next two spools state that feature directly. This spool suits shoppers who care most about buying the brand’s own material and want the packaging details spelled out.

Bamboo 1.75MM PLA Silk+ Filament Shiny
Best for: AMS owners wanting chrome-like shine
Pros
- RFID tag for AMS setup
- Chrome-like gloss claim
- Enhanced layer adhesion claim
- One-year warranty listed
Cons
- Third-party 3DTOOLS product, not Bambu Lab
- No drying or packaging details
The Bamboo 1.75MM PLA Silk+ Filament Shiny is made and sold by 3DTOOLS, not by Bambu Lab, even though its title says “Bamboo” and it uses the same Gold 13405 color name. It is sold as a 1kg roll of 1.75mm PLA Silk+ with a ±0.03mm tolerance, and it is listed for the Bambu Lab A1, A1 mini, X1 and P1 series with the AMS.
Its headline feature is an RFID tag. RFID is a small chip in the spool that stores the print settings; when the AMS (Bambu Lab’s Automatic Material System, the box that feeds several spools to the printer) reads it, the printer picks the right temperatures and profile for you. For a first-time owner, that removes the most confusing step of switching materials. The listing also describes a “shiny like chrome” sheen, enhanced layer adhesion and better resistance to bending and impact, and it lists a one-year warranty.
The listing does not say whether the spool is vacuum-sealed or packed with desiccant, so plan to store it in a dry box once opened. This spool suits AMS owners who want the brightest, most mirror-like gold and like the idea of loading a spool and pressing print. If you would rather stick to the brand’s own spool, the first pick is the safer choice. Our guide to bambu labs filament explains the wider range if you want other colors to pair with gold.

Bamboo Original PLA Silk+ Filament Glossy
Best for: Decor makers wanting satin-smooth gold
Pros
- RFID stores print settings
- Smooth, near-invisible layer lines claim
- Beginner-friendly handling
- Lists many Bambu Lab models
Cons
- Third-party TEWIRROW product, not Bambu Lab
- No warranty or packaging details listed
The Bamboo Original PLA Silk+ Filament Glossy comes from TEWIRROW, another third-party maker, and is sold for the Bambu Lab A1, A1 mini, X1, X1C, P1P and P1S with the AMS. Like the 3DTOOLS spool, it is a 1kg roll of 1.75mm silk PLA in Gold 13405 and includes an RFID chip that stores the recommended print settings, so a compatible AMS can configure the printer automatically.
The listing puts its focus on surface quality. It describes a glossy finish that mimics silk or satin, layer lines that bond so cleanly the surface feels almost smooth to the touch, and a metallic-like depth of color that shifts slightly as the light changes. It also calls the material forgiving and suitable for beginners, much like standard PLA. The listing does not give a diameter tolerance, warranty or packaging details, so those remain unknowns.
This spool suits gift crafters who print ornaments, vases, busts and display pieces where a soft satin glow matters more than a hard chrome look. If a published tolerance or a warranty term matters to you, the 3DTOOLS spool lists both, and the BambuLab spool lists its tolerance and sealed packaging.
How to Choose the Right Bambu Lab 3D Printer Filament
Start with who makes it. If the goal is a genuine Bambu Lab product, only the Bambu Lab PLA Silk+ Filament 1.75mm is listed under that brand. The two “Bamboo” spools are third-party filaments made to work with Bambu Lab printers, which is perfectly fine for printing, but the gift should be described honestly.
Next, check whether the printer has an AMS. Both third-party spools state an RFID tag that lets the AMS load settings automatically. The BambuLab spool’s listing does not mention RFID, so a new owner may need to choose the silk PLA profile by hand.
Then think about the finish. Silk PLA vs regular PLA comes down to looks: regular PLA prints with a matte or light satin surface, while silk PLA includes additives that give a shiny, metallic sheen that hides layer lines. The 3DTOOLS spool leans toward chrome-like shine, the TEWIRROW spool toward a satin glow, and the BambuLab spool promises a silk-like metallic gold. Silk PLA is generally a little less stiff than regular PLA, so use it for decorative pieces rather than parts that need to carry a load.
Finally, consider storage. Only the BambuLab spool lists vacuum sealing with desiccant. Whichever you buy, keep opened spools dry; a sealed bin or filament dryer helps the shine last from the first print to the last. If your recipient also prints outdoor parts, our bambu lab asa guide covers a tougher, weather-resistant material that pairs well with decorative silk prints.
FAQ
Is the “Bamboo” filament made by Bambu Lab?
No. Based on the listings, the Bamboo 1.75MM PLA Silk+ Filament Shiny is made by 3DTOOLS and the Bamboo Original PLA Silk+ Filament Glossy is made by TEWIRROW. Both are designed for Bambu Lab printers, but only the Bambu Lab PLA Silk+ Filament 1.75mm names BambuLab as its brand.
What is silk PLA and how is it different from regular PLA?
Silk PLA is PLA with additives that give prints a glossy, metallic, silk-like surface. Regular PLA looks flatter. Silk PLA is great for decorative gold prints, while regular PLA is often a better pick for stiff, functional parts.
Will these gold filaments work in the Bambu Lab AMS?
The two third-party spools are listed for Bambu Lab printers with the AMS and include RFID tags so the system reads their settings. The BambuLab spool is described as compatible with Bambu Lab printers, but its listing does not mention RFID, so you may need to select a profile manually.
Which gold filament should I buy as a gift?
If the recipient cares about owning the brand’s own material, choose the Bambu Lab PLA Silk+ Filament 1.75mm. If they have an AMS and love a mirror-like shine, the 3DTOOLS spool fits. For satin-smooth decor, the TEWIRROW spool is the natural choice.
Do I need to dry silk PLA before printing?
A fresh, sealed spool usually prints well straight away. Once opened, PLA can absorb moisture over time, which can dull the shine and cause stringing, so storing it in a dry container is a good habit for all three spools.
Are these spools the same size?
Yes. All three are listed as 1kg spools of 1.75mm filament, which is the standard diameter Bambu Lab printers use.
