Filament Spectrum 81018 PLA Silk 1.75 mm 1 kg Multicolour (Ocean Melange)

Spectrum Filaments 81018 PLA Silk 1.75 mm 1 kg Multicolour (Ocean Melange) is a silk-finish polylactic acid filament designed for FDM consumer 3D printers. The 1.75 mm diameter spool contains 1 kg of PLA that prints with a glossy, smooth surface and displays a multicolour Ocean Melange gradient suitable for decorative items, prototypes and scale models. The filament is supplied on a single spool in a protective box for straightforward installation and use on compatible printers.

Advantages

This PLA Silk material produces a reflective, smooth surface that reduces visible layer lines compared with standard matte PLA, enabling attractive finishes without post-processing. The multicolour Ocean Melange coloration creates gradual color transitions during printing, allowing single-extrusion prints with varied visual effects. The 1.75 mm diameter provides broad compatibility with common consumer FDM hotends and extruders, and the 1 kg spool balances print time and storage convenience.

Suitable for

• Decorative parts and display objects with a silk/glossy finish
• Concept models and visual prototypes requiring colour variation
• Scale models, miniatures and dioramas
• Non-functional aesthetic components and customised gifts

Key specifications

• Material: Polylactic acid (PLA), silk finish
• Diameter: 1.75 mm
• Net filament weight: 1 kg
• Colour: Multicolour (Ocean Melange gradient)
• Format: Single spool supplied in box for consumer printers

How to use

Load the 1.75 mm filament into a compatible FDM printer following the printer manufacturer’s loading procedure. Typical printing temperatures for PLA silk range from 190–220 °C; start in the mid-range and adjust by ±5 °C based on adhesion and surface appearance. Use a print bed temperature of 20–60 °C or unheated bed with suitable adhesion aids. Reduce print speed slightly compared to standard PLA to improve surface gloss and colour transitions. Store the spool in a dry environment when not in use to maintain filament quality.

Usage recommendations

For best visual results, print at moderate speeds (30–60 mm/s) and layer heights between 0.1–0.3 mm to balance surface finish and detail. Enable retraction settings to minimise stringing and calibrate extrusion multiplier to avoid over-extrusion that can dull the silk effect. If stronger adhesion is needed, apply a thin layer of glue stick or use a PEI sheet; avoid high bed temperatures or prolonged thermal exposure to preserve colour transitions.
