Spectrum ASA Glow in the Dark 3D Printing Filament, 1.75mm, 1kg, Yellow-Green

Spectrum ASA Glow in the Dark 3D printing filament is a high-performance material engineered for durability and visual impact. This 1.75mm filament combines the robust mechanical properties and UV resistance of standard ASA with specialized phosphorescent pigments, allowing printed objects to emit a bright yellow-green glow after exposure to light. It is specifically formulated to provide excellent layer adhesion and reduced warping, making it a reliable choice for both functional engineering parts and creative decorative projects that require visibility in low-light conditions.

Advantages

The primary benefit of this filament is its exceptional resistance to environmental factors, including intense UV radiation and varying weather conditions, which ensures that parts maintain their structural integrity and aesthetic appeal during long-term outdoor use. The material is significantly easier to print than traditional ASA formulations, offering improved dimensional accuracy and compatibility with a wide range of 3D printers. Its unique ability to store light energy and release it as a vivid glow provides a functional advantage for safety-related applications, while the high mechanical strength ensures that printed components can withstand physical stress.

Suitable for

• Outdoor signage and safety markers
• Emergency exit indicators
• Architectural models and prototypes
• Decorative objects with glow effects
• Automotive and engineering components

When it may not be suitable

This filament may not be the best choice for applications requiring extreme chemical resistance or high-temperature environments exceeding the thermal limits of ASA. Additionally, it is not recommended for food-contact items or medical devices due to the nature of the additives used for the glow effect.

How to use

To achieve the best results, ensure your 3D printer is calibrated for ASA materials. While this filament is easier to print than standard ASA, using an enclosed printer is recommended for larger parts to maintain consistent temperatures and prevent warping. Adjust your nozzle temperature between 210°C and 270°C depending on your specific printer setup and print speed. Ensure the print bed is heated to 40–70°C and use an appropriate adhesive if necessary to improve first-layer adhesion. Keep cooling fan usage low, typically between 0–20%, to maintain optimal layer bonding.

What to consider before purchase

• Check if your printer supports high-temperature materials and has an enclosure.
• Ensure your printer is compatible with 1.75mm diameter filament.
• Consider the size of your prints, as larger objects may require a heated chamber to prevent shrinkage.
• Verify that the glow-in-the-dark effect meets your specific visibility requirements for the intended application.

Usage recommendations

For optimal glow intensity, expose your finished prints to direct sunlight or strong artificial light sources. Regularly clean your print bed and ensure the filament is kept dry in a sealed container when not in use to maintain its high-quality printing characteristics.
