Glow in Dark PLA Bundle 1.75mm 8-Pack - Multi Color 2kg Bundle

In this review of the SUNLU Glow in Dark PLA Bundle, the conclusion is straightforward: this 2kg, eight-roll pack is best for hobbyists and makers who want a variety of small glow prints without buying full-size spools. The bundle includes eight neat 250g rolls in a mix of black, white and several glow-enabled colors, and the single biggest reason to buy is the convenience of multiple luminous hues ready for festival decorations, toys, or small prototypes. The review finds the filament generally reliable, with good dimensional tolerance, but notes some users report brittleness and occasional clogging.

Key Features

• Mixed 8-roll set: Provides eight 0.25kg spools in black, white and six glow variations so projects can use multiple colors without large spools.
• Glow in the dark formulation: Phosphorescent material stores light energy and produces visible glow after exposure, improving with UV charging.
• Consistent diameter: 1.75mm filament held to a stated dimensional accuracy of +/- 0.02mm, which helps with predictable extrusion and layer consistency.
• Neatly wound spools: The tidy winding reduces the risk of tangles and makes feeding into printers smoother for small prints and decorations.
• PLA base and safety: Made from natural PLA materials for reliable, low-warp printing and safe use in consumer settings and parties.

Who It's For

This bundle is aimed at hobbyists, craft makers, cosplayers and educators who frequently print small decorative items and want multiple glow colors available immediately. The 250g spool size is well suited to experiments, short runs and festival decorations rather than long continuous production runs.

Those who need large-volume, continuous printing or who require absolute toughness for mechanical parts should look elsewhere; a single 1kg spool or a filament formulated for high impact resistance will be a better fit for heavy-duty functional parts.

Pros & Cons

Pros

• Good variety of colors and glow effects in one economical package, useful for multi-color projects.
• Dimensional tolerance of +/- 0.02mm helps maintain consistent extrusion and print quality.
• Neatly wound spools reduce tangles and filament feeding problems when handled carefully.
• Better glow performance when charged with a strong light source or UV, making prints eye-catching at night.

Cons

• Some users report occasional brittleness in parts and a risk of clogging in certain setups, so drying and careful retraction tuning may be needed.
• 250g spool size is small for longer prints, so frequent spool changes are required for larger projects.

Our Verdict

The SUNLU Glow in Dark PLA Bundle is a strong value for makers who prioritize variety and creative glow effects in small prints.

Frequently Asked Questions

How long does the filament glow?
The glow duration depends on the charge and light source; UV charging produces the strongest and longest-lasting glow, while standard indoor lights give a shorter effect.

Is this filament easy to print on desktop printers?
Yes, the PLA base is user friendly and prints well on most desktop printers using 200-230C nozzle and a 50-65C bed, though tuning retraction and drying may reduce clog risk.

Are these full-size spools?
No, each spool is 250g, making them ideal for small projects and color testing rather than long continuous runs.
