Filament spool BambuLab Refill PLA Basic 1.75 mm 1 kg — Blue Grey

BambuLab Refill PLA Basic 1.75 mm 1 kg — Blue Grey is a standard polylactic acid filament supplied on a 1 kg spool with a 1.75 mm diameter. It is formulated for fused filament fabrication and offers reliable extrusion, dimensional stability and predictable layer adhesion for everyday 3D printing tasks. The Blue Grey color provides a neutral, professional look suitable for prototypes, functional parts and hobbyist models. The filament is compatible with printers that accept 1.75 mm PLA and is intended for users seeking an easy-to-print, general-purpose material.

Advantages

This PLA filament delivers consistent diameter tolerance and stable flow for long prints, reducing the need for frequent re-calibration. Its formulation supports good layer bonding and clean surface finish for standard printing settings, while the Blue Grey pigmentation provides uniform color across prints. The product is supplied on a convenient 1 kg spool that fits most consumer and prosumer extruders designed for 1.75 mm filament.

Suitable for

• Rapid prototyping and concept models
• Functional parts with moderate mechanical demands
• Hobbyist models, figurines and miniatures
• Everyday household prints and fixtures

Key specifications

• Material: Polylactic acid (PLA)
• Diameter: 1.75 mm
• Spool weight: 1 kg net filament
• Color: Blue Grey
• Manufacturing type: Fused filament fabrication (FFF/FDM) compatible

How to use

Load the spool onto your printer’s filament holder and thread the filament through the extruder path according to your printer manufacturer’s instructions. Set nozzle and bed temperatures to recommended PLA ranges for your machine and slice the model with settings appropriate for 1.75 mm PLA, such as moderate print speed and standard retraction. Monitor the first layers for proper adhesion and extrusion, and adjust bed leveling, temperature or flow rate as needed to achieve the desired surface quality and dimensional accuracy.

Usage recommendations

Store the filament in a dry, dust-free environment and use desiccant where possible to maintain print quality. For improved surface finish and strength, consider printing at slightly elevated temperatures within your printer’s PLA range and use a heated bed when adhesion is an issue. Pause prints only when the extruder is stable to avoid stringing or nozzle clogs.
