## Long description

Spectrum Filaments 81020 PLA Silk 1.75 mm 1 kg Multicolour (Earth Blend) is a 1 kg spool of silk-finish polylactic acid (PLA) filament formulated for FDM/FFF 3D printers using a 1.75 mm feed. The multicolour Earth Blend provides gradual colour transitions and a glossy, satin surface ideal for decorative parts, presentation models and visual prototypes. The filament is supplied on a single spool in a box and is compatible with standard PLA printing temperature ranges and settings.
Advantages
The silk PLA composition produces smooth, reflective surfaces with reduced visible layer lines compared to standard matte PLA, improving the appearance of finished prints without additional post-processing. The multicolour gradient effect creates visually appealing transitions within single prints, allowing colour variation without the need to change filament. Being PLA-based, the material offers good dimensional stability, low warping and ease of printing on most open and enclosed desktop FDM printers.
Suitable for
 Decorative objects and display pieces
 Visual prototypes and concept models
 Cosmetic parts and non-load-bearing housings
 Artistic prints and small sculptures
Key specifications
 Material: Polylactic acid (PLA) with silk finish
 Nominal diameter: 1.75 mm
 Net weight: 1 kg
 Colour: Multicolour gradient (Earth Blend)
 Recommended printing: standard PLA temperature range and settings
How to use
Load the 1.75 mm filament into a compatible FDM/FFF 3D printer following the printer manufacturer’s filament loading procedure. Select standard PLA print settings including nozzle temperature within the manufacturer-recommended PLA range, bed temperature as needed for adhesion, and moderate print speeds to preserve the silk surface quality. Calibrate extrusion and first-layer height before printing multicolour or detailed parts to ensure consistent colour transitions and surface finish.
Usage recommendations
Store the filament in a dry environment, preferably in a sealed container with desiccant to avoid moisture uptake that can affect print quality. Use a nozzle diameter and layer height combination suitable for visible surface detail; larger layers will emphasize the silk sheen while finer layers improve resolution. Avoid prolonged exposure to direct sunlight and high humidity during storage and printing.
