Not only do these filaments make my prints visually striking in low light or complete darkness, but they also serve practical purposes. For example, I’ve printed keychains and emergency tools that are easy to find at night, which is incredibly convenient.
Additionally, glow in the dark filaments allow me to experiment with unique designs that stand out, especially for decorative items or cosplay accessories. The ability to create objects that literally come alive when the lights go out makes my work feel more dynamic and fun. Overall, I see glow in the dark filaments as an essential material that enhances both the aesthetics and usability of my 3D prints.
My Buying Guides on 3D Print Glow In The Dark Filaments
When I first started exploring 3D printing with glow in the dark filaments, I quickly realized there’s more to choosing the right filament than just picking one that glows. Over time, I’ve learned to focus on several key factors to get the best results. Here’s my guide based on what worked for me.
1. Understand the Types of Glow in the Dark Filaments
There are a few different types of glow in the dark filaments, mostly based on the base material and the phosphorescent additive. The most common base materials are PLA, ABS, and PETG. I personally prefer PLA for its ease of use, especially with glow additives that tend to be a little more abrasive. Make sure the filament clearly states it contains phosphorescent powder for that glowing effect.
2. Brightness and Glow Duration
One of the first things I checked was how bright the filament glows and for how long. Some filaments glow very brightly but only for a few minutes, while others have a longer-lasting but dimmer glow. I found it helpful to look for filaments that specify glow duration in their description or reviews. Also, keep in mind that charging the filament under a strong light source before printing can enhance the glow.
3. Color of Glow
Glow in the dark filaments don’t all glow the same color. Common glow colors include green, blue, and aqua. Green tends to be the brightest and longest-lasting in my experience, but blue and aqua can look really cool depending on your project. Think about what color fits your design and environment best.
4. Printability and Settings
Glow in the dark filaments can be a bit more challenging to print because the phosphorescent particles can make the filament more abrasive and sometimes clog the nozzle. I always recommend using a hardened steel nozzle if you plan to print a lot with these filaments. Also, print temperatures might be slightly different from regular PLA or ABS, so check the manufacturer’s recommended settings and do a test print first.
5. Filament Diameter and Quality
Consistency in filament diameter is crucial for smooth printing. I look for brands that provide tight tolerance specifications (±0.02 mm is ideal). Cheaper filaments sometimes have inconsistent diameters, which can cause under or over-extrusion and ruin a glow effect. Also, consider filament spool size based on your project needs.
6. Price vs. Performance
Glow in the dark filaments tend to be pricier than regular filaments due to the special additives. I balance price with performance by reading reviews and sometimes buying smaller spools first to test. It’s worth investing a bit more for a filament that glows well and prints reliably.
7. Safety Considerations
Since these filaments contain phosphorescent materials, I always check if the filament is non-toxic and safe for indoor use. Most reputable brands will specify safety info. Also, good ventilation is always a plus when printing with any specialty filament.
8. Where to Buy and Brands I Trust
I’ve found that established brands like eSUN, Overture, and Atomic Filament usually offer consistent quality glow in the dark filaments. Buying from trusted retailers or directly from manufacturers helps ensure authenticity. Beware of knock-offs that might not glow well or print smoothly.
Final Thoughts
Choosing the right glow in the dark filament requires a bit of trial and error, but by focusing on glow brightness, printability, and filament quality, I’ve been able to create some amazing glowing prints. Remember to charge your prints under strong light and experiment with print settings to get the best glow effect. Happy printing!
