Filament BambuLab Refill PLA Matte 1.75 mm 1 kg — Dark Blue

BambuLab Refill PLA Matte 1.75 mm 1 kg — Dark Blue is a PLA thermoplastic filament designed for FDM/FFF 3D printers that accept 1.75 mm material. The filament delivers a consistent matte surface finish and is formulated for reliable extrusion, dimensional stability and good layer adhesion. Offered on a 1 kg spool in a dark blue shade, it is intended for functional prototypes, decorative parts and hobby prints where reduced shine and a subdued appearance are preferred.

Advantages

The matte formulation reduces surface gloss, minimizing light reflections and improving the visual appeal of painted or unpainted parts. The filament is manufactured to a consistent diameter and roundness to support steady feed and fewer print disruptions. It provides predictable printing behaviour on standard PLA settings and exhibits good layer bonding for durable parts. Dark blue coloration is stable across typical printing temperatures and offers reliable colour reproduction for multi-part assemblies.

Suitable for

• Functional prototypes and concept models requiring a non-gloss surface
• Decorative objects, figurines and display pieces with matte finish
• Hobby and educational projects where easy printing and visual consistency are important
• Parts that may be post-processed with sanding, painting or adhesive bonding

Key specifications

• Material: Polylactic Acid (PLA) formulated for matte finish
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg net filament
• Finish: Matte, low gloss
• Colour: Dark blue
• Compatibility: Standard FDM/FFF 3D printers supporting 1.75 mm PLA

How to use

Load the 1.75 mm filament into a compatible FDM/FFF 3D printer following the printer manufacturer's filament loading procedure. Use typical PLA printing temperatures and settings as a starting point; adjust nozzle temperature, bed temperature and print speed to optimise adhesion and surface quality for your specific printer and environment. Allow printed parts to cool gradually to reduce warping and ensure consistent matte appearance. When changing spools, purge the hotend to remove remnants of the previous material.

Usage recommendations

Start with standard PLA settings (nozzle temperatures commonly between 190–220 °C and a heated bed if available) and fine-tune based on observed flow and layer adhesion. Use a stable, clean spool holder and maintain dry storage to prevent moisture absorption. For improved surface uniformity, consider printing with moderate layer heights and lower print speeds; sand or prime before painting if a smoother finish is required.
