Spectrum PLA Silk 1.75mm Aluminium Silver 1kg 3D Printer Filament

With a diameter tolerance of ±0.03 mm, this Spectrum PLA Silk filament delivers consistent extrusion and a silky metallic finish that makes printed parts look almost cast from aluminium. The 1.75 mm diameter and 1 kg net weight spool are compatible with most FDM 3D printers, while the recycled cardboard spool keeps waste low.

Overview

Spectrum PLA Silk in Aluminium Silver is a premium 3D printing filament that combines the ease of PLA with a stunning silk-like sheen. The material prints at moderate temperatures (200–230 °C) and often requires no heated bed, making it accessible for beginners and reliable for experienced makers. Each spool is vacuum-sealed with desiccant to protect against moisture and ensure consistent quality from the first print to the last.
