SUNLU Silk PLA+ Filament 1.75mm, Chrome Like Gloss Finish, 1kg, Gold Review (2026)
Updated September 21, 2026 · Research-based review
Our verdict
A step up for buyers who already like silk PLA but want a shinier, chrome-like gold finish and SUNLU's newer PLA+ base formula. The main strength is a glossier out-of-printer look than classic silk PLA; the main trade-off is a newer formulation with less accumulated community printing experience than SUNLU's longer-running silk line.

What we liked
- + Chrome like gloss finish is shinier than regular silk PLA

Trade-offs
- - High gloss exaggerates layer lines on shallow curved surfaces
- - Newer formulation with fewer shared profiles than classic silk
Chrome-like finish versus classic silk
SUNLU markets this filament as an upgraded Silk PLA+ line with a chrome-like gloss finish, described on the Amazon listing and SUNLU's own store as a smooth silk texture with an upgraded formula for more stable printing compared to earlier silk filaments. The chrome branding signals a shinier, more reflective result than SUNLU's standard shiny silk PLA, aimed at buyers who want prints that look closer to a polished metal surface without painting or post-processing. SUNLU's blog content on their silk lines describes achieving this glossy, satin-like look straight off the printer, consistent with how silk-family filaments generally work.
PLA+ base and what that adds
This filament is built on a PLA+ base rather than standard PLA, and PLA+ formulations generally aim for improved toughness and ductility over base PLA while keeping similar print temperatures and ease of use. SUNLU's listing does not provide independent mechanical test numbers for this specific chrome silk variant, so buyers should treat the PLA+ toughness claim as a formulation goal rather than a verified strength figure. Even with a PLA+ base, silk-style additives that create the glossy look typically still reduce interlayer bond strength somewhat compared to non-silk PLA+, so this filament should still be treated primarily as a decorative option rather than a structural one. Anyone weighing this against a plain PLA+ spool should expect a visual upgrade first and a modest durability upgrade second, not the other way around.
Print settings and tolerance
SUNLU's listings and store pages for this Chrome Like Gloss Finish line state a 1.75mm diameter with roughly plus or minus 0.02mm precision tolerance, recommended nozzle temperatures generally in the 205 to 230 degree Celsius range depending on the specific source, and bed temperatures around 60 to 80 degrees Celsius. Recommended print speed sits around 30 to 60 millimeters per second, similar to SUNLU's other silk filaments, and slower speeds within that window tend to produce a glossier, smoother surface on silk-style filaments generally. These settings are broadly compatible with most consumer FDM printers without special hardware requirements.
Gold color and where it shines
The gold chrome color is well suited to awards, trophies, cosplay accents, jewelry-style prints, and ornamental pieces where a metallic look adds clear visual value, and the increased gloss over standard silk PLA should hide layer lines effectively on curved surfaces. As with any high-gloss filament, that same shine can make shallow surface imperfections and layer transitions more visible on flatter faces under strong direct light, since gloss reflects unevenness rather than diffusing it the way a matte finish does. Buyers wanting a mirror-like decorative piece are the target audience rather than anyone prioritizing subtlety.
Who should buy this spool
This filament fits hobbyists who already enjoy silk PLA results and want to try SUNLU's newer, glossier chrome formulation, particularly for gold-toned decorative and gift prints. It also suits buyers comfortable with a less established filament line, since being newer means fewer shared community slicer profiles exist compared to SUNLU's classic silk PLA. It is not the right choice for functional or load-bearing prints given the interlayer weaknesses typical of silk-style filaments, nor for buyers who want a filament with a long, proven print history and extensive third-party profile support already dialed in for common printer and slicer combinations.
Frequently asked questions
How is this different from SUNLU's regular silk PLA?
SUNLU markets it as an upgraded Silk PLA+ formula with a chrome-like gloss finish, aiming for a shinier result and improved print stability compared to classic silk PLA.
What print temperature does SUNLU recommend?
SUNLU's listings indicate a nozzle range roughly between 205 and 230 degrees Celsius and a bed temperature around 60 to 80 degrees Celsius, depending on the source.
Is this filament suitable for functional parts?
It is better suited to decorative prints, since silk-style filaments including PLA+ variants generally have weaker interlayer bonding than non-silk PLA.
What is the filament's diameter tolerance?
SUNLU lists a tolerance of about plus or minus 0.02mm on the 1.75mm diameter.
