Filament eSun EPLA-LUMINOUS 1.75 mm Green 1 kg — PLA luminous 3D printer filament

eSun EPLA-LUMINOUS 1.75 mm Green is a 1 kg spool of PLA-based 3D printer filament engineered to glow in the dark after exposure to light. With a 1.75 mm nominal diameter, this luminous PLA is compatible with standard desktop 3D printers that accept 1.75 mm filament and is intended for printing visible parts, decorative models, cosplay accessories and functional items requiring low-light visibility. The material prints using typical PLA temperature ranges and behaves similarly to conventional PLA in terms of dimensional stability and layer adhesion.

Advantages

The luminous formulation stores light energy and emits a green glow in darkness, enhancing visibility of printed objects without additional electronics. As a PLA variant, it offers ease of printing on common 3D printers, low warpage, and good surface finish. The filament is supplied on a 1 kg spool with consistent 1.75 mm diameter to support reliable extrusion and predictable print results.

Suitable for

• Decorative items and signage that need glow-in-the-dark effect
• Cosplay props and costume elements requiring visibility in low light
• Prototypes and concept models where visual impact is important
• Functional parts and safety markers that benefit from passive illumination

Key specifications

• Material base: PLA (polylactic acid) with photoluminescent additives
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg net filament
• Color in daylight: green; emits green glow after charging
• Compatibility: standard 1.75 mm extruders and hotends
• Typical printing behavior: low warpage, good layer adhesion, smooth surface finish

How to use

Load the filament into a 3D printer configured for 1.75 mm material and use standard PLA print settings as a starting point. Recommended nozzle temperatures typically fall within common PLA ranges; adjust temperature and print speed to match your specific printer and model geometry. Allow printed parts to be exposed to a light source to charge the photoluminescent additives; the glow intensity and duration depend on exposure time and light intensity. Store the spool in a dry environment and keep it sealed when not in use to prevent moisture uptake.

Usage recommendations

For best glow performance, expose printed parts to strong white or UV light for several minutes prior to use in darkness. Use a heated bed if needed to improve first-layer adhesion on your printer, but reduce bed temperature compared with semicrystalline materials. When printing fine details, consider slightly lower print speeds and optimized retraction settings to maintain surface quality.
