Filament BambuLab PLA Glow 1.75 mm 1 kg — Glow Blue, reusable spool included

BambuLab PLA Glow 1.75 mm 1 kg — Glow Blue is a photoluminescent PLA filament formulated for FDM/FFF 3D printers. The 1.75 mm filament comes on a reusable spool and is designed to charge under ambient or direct light and emit a visible blue-green glow in low-light environments. It is compatible with standard PLA print settings and suitable for a range of applications where glow-in-the-dark properties are needed without special print hardware.

Advantages

This BambuLab PLA Glow filament combines standard PLA printing behavior with photoluminescent additives that store light and release it in darkness. The reusable spool reduces waste and simplifies storage and handling. The material prints at conventional PLA temperatures, providing predictable layer adhesion, dimensional stability and surface finish typical of PLA while delivering a durable glow effect after exposure to light.

Suitable for

• Prototyping and concept models that need visibility in low light
• Decorative prints, signage and accents with glow effects
• Toys, cosplay parts and props requiring photoluminescent properties
• Functional parts where nighttime or low-light visibility is beneficial

Key specifications

• Material type: PLA with photoluminescent additive
• Diameter: 1.75 mm nominal
• Net weight: 1 kg filament per spool
• Color/effect: Glow Blue (charges under light to emit blue-green glow)
• Packaging: Reusable spool for storage and filament management
• Compatibility: Designed for FDM/FFF 3D printers using standard PLA settings

How to use

Load the 1.75 mm filament into your FDM/FFF 3D printer following the manufacturer's filament-loading procedure. Use standard PLA printing temperatures and cooling settings as a baseline; typical extrusion temperatures for photoluminescent PLA are similar to regular PLA but may require fine-tuning for optimal surface finish. Ensure the print bed adhesion method you use is compatible with PLA and that the spool is mounted so filament feeds smoothly. After printing, expose the part to ambient or direct light to charge the photoluminescent additive for subsequent glow performance.

Usage recommendations

To maximize glow performance, expose printed parts to strong light (sunlight or a bright LED source) for several minutes to hours depending on intensity. Avoid prolonged exposure to temperatures above typical PLA softening points and store the reusable spool in a cool, dry place to preserve filament quality. If stringing or flow issues appear, adjust retraction and print temperature within the normal PLA range. For best results on fine details, test layer height and cooling settings on a small sample before final printing.
