3D printer filament Spectrum SILK PLA 1.75 mm Sapphire Blue 1 kg

Spectrum SILK PLA 1.75 mm Sapphire Blue is a 1 kg spool of PLA filament designed for FDM/FFF 3D printers that accept 1.75 mm material. The silk variant of PLA delivers a glossy, satin-like finish that enhances surface appearance without additional post-processing. Formulated from PLA, a biodegradable thermoplastic, this filament is suitable for printing detailed models, decorative parts and visual prototypes where appearance and surface quality are important.

Advantages

The silk finish produces a smooth, reflective surface with subtle sheen that reduces the visibility of layer lines. PLA base material offers stable printing behavior, low warping and compatibility with a wide range of desktop 3D printers. The filament comes wound on a 1 kg spool and is ready for immediate use with standard extruders calibrated for 1.75 mm filament. Recommended printing temperature range supports consistent extrusion and good interlayer adhesion.

Suitable for

• Decorative models and ornaments
• Display pieces and visual prototypes
• Miniatures and figurines with fine detail
• Household items with an attractive surface finish

Key specifications

• Material type: PLA (polylactic acid)
• Color: Sapphire Blue with silk (satin-gloss) effect
• Diameter: 1.75 mm
• Recommended extrusion temperature: 190–220 °C
• Net weight: 1,000 grams (1 kg)

How to use

Load the filament into an FDM/FFF 3D printer configured for 1.75 mm filament. Set the nozzle temperature within the recommended range of 190–220 °C; adjust within this window according to your specific printer, nozzle size and print speed to achieve optimal flow. Use a heated bed if needed for adhesion, although PLA often prints well on a cool bed with appropriate build surface or adhesion aids. Calibrate extrusion multiplier and retraction settings to reduce stringing and ensure clean detail reproduction. Store the spool in a dry environment when not in use to maintain filament quality.

Usage recommendations

For best surface quality when printing decorative parts, use moderate print speeds and layer heights between 0.1–0.2 mm, a well-tuned cooling fan, and a nozzle compatible with fine-detail work. Dry the filament if stored in humid conditions before printing to avoid bubbles and inconsistent extrusion.
