Discover Granite Grey - Spectrum ReFill Premium PLA High Speed, a 1.75 mm, 1 kg filament designed to print faster, with flawless precision and finish. This ReFill is wound on an eco-friendly cardboard core, perfectly compatible with Bambu Lab reusable spools, eliminating the need for adapters and reducing plastic waste.

If you do not have a Bambu Lab reusable spool, no problem: download and print a simple spool model available on the Spectrum website and use your ReFill filament right away, without compromising on eco-friendliness.

Fast and precise printing: Premium PLA High Speed is specially formulated to reach speeds of up to 800 mm/s, with smooth extrusion, efficient cooling, and accurate detail reproduction. Mechanical properties are improved: high hardness, tensile strength, and excellent layer adhesion for strong, accurate parts.

Its appearance is ideal for rapid prototypes, concept models, and industrial design projects, while offering a smooth surface and a striking aesthetic finish. The filament features high rigidity and virtually no warping after cooling, even for thin geometries.

The colors are varied, with a wide range including UV-reactive Neon shades to let your creativity run free, while remaining 100% biodegradable and industrially compostable, illustrating our commitment to the environment.
