OzFDM PLA Glow in the Dark Rainbow Filament
OzFDM’s PLA Glow in the Dark Rainbow (GITDR) 1.75 mm filament delivers a vibrant fusion of colour, creativity, and functionality to your everyday prints. In daylight, it showcases a captivating, multi coloured gradient, while in darkness, it releases a soft, luminous glow after absorbing and storing light energy. This dual effect design takes traditional glow in the dark printing to the next level, adding both visual excitement and unique character.
Formulated from high quality Polylactic Acid (PLA), GITDR is infused with engineered colourants and phosphorescent pigments that work together to produce shifting rainbow hues and long lasting glow effects. The rainbow transitions are achieved through precision colour blending during manufacturing, where multiple pigments are carefully metered into molten PLA, allowing the filament to transition smoothly through a pre-set colour sequence as it’s wound. Combined with the glow component, which uses phosphorescent additives to charge under light and emit in darkness, the result is a truly dynamic filament that prints consistently and beautifully. Beyond its visual appeal, GITDR maintains similar print reliability and extrusion as standard PLA, making it ideal for signage, decorative models, and artistic statement pieces. It’s designed for creators who want their prints to shine, both in daylight and after dark.

Colours from the Rainbow
PLA Glow in the Dark Rainbow Filament Colour Range
We are proud to offer 1 distinct shade of PLA Glow in the Dark Rainbow; the hues on the filament range from bold primaries to soft pastels, with a consistent formulation that delivers rich pigmentation and a bright glow in the dark.
Approximate Rainbow Transition: Shades may vary between spools. The hex codes shown are intended only as a visual guide, as colour transitions can differ throughout each roll. These values have been provided to help you better understand the potential range of tones within the filament.
Disclaimer on Colour Accuracy: The filament colours displayed above have been specified using online hex code sources and our Nix Mini 3 Colour Sensor. Hex codes may slightly differ from the actual physical product due to differences in screen calibration, lighting, and digital representation.
Technically Yes, Suggested No!
AMS-Compatible? Not Recommended
- PLA Glow in the Dark Rainbow is a standard PLA base, but the additives of the phosphorescent powder make the filament highly abrasive, which can affect consistent printing on your AMS. Printing with caution and specific modifications to your AMS makes it possible to create quality prints.
- However, if you are printing consistently with PLA GITDR on an AMS machine, you are more likely to create wear on internal components a lot quicker than when using highly compatible filaments. Damages can specifically occur to the feeding funnels, as well as wear on standard brass nozzles and PTFE tubes.
Watch your prints shift through radiant hues in daylight, then glow with a soft, lasting brilliance after dark.
Colour That Comes Alive
Dual Visual Effect – Day and Night Appeal
GITDR PLA delivers two stunning visual experiences in one filament. During the day, it displays a dynamic rainbow gradient that shifts seamlessly through a spectrum of vivid tones.
Once the lights go out, the embedded phosphorescent pigments release a soft, radiant glow, transforming your print into an eye catching display.
Whether it’s artistic pieces, signage, or novelty models, this filament ensures your creations stand out in every light setting.
Precision-Blended for Seamless Transitions
Each spool is produced through a carefully controlled colour blending process, where multiple pigments are metered into molten PLA to form consistent, gradual transitions.
This technique allows each section of filament to move through a planned colour sequence without harsh breaks or pattern repetition.
The result is smooth, flowing gradients that bring depth and motion to even the simplest prints.
Reliable Performance with Creative Freedom
Beyond its visual features, GITDR maintains similarities in the printing characteristics of standard PLA.
It adheres well to the build plate, flows evenly through the nozzle (if modified to a larger hardened nozzle or tailored for your specific printer's needs), and requires no high temperature setup.
Makers can achieve dependable, high quality results while enjoying the added creative freedom of colour shifting, glow enhanced effects, making it a perfect combination of performance and imagination.

Understanding PLA Glow in the Dark Rainbow at a Glance
- The results highlight GITDR’s strong balance between printability and visual performance.
- While its strength and heat resistance are moderate, it excels in ease of printing and offers reliable durability for decorative or light functional parts.
- Its vivid glow, colour transitions, and good UV stability make it a standout option for creative applications where appearance matters most.
FAQ's
Tips & Tricks
If using the AMS machine:
- Watch consistently increased friction, which may cause unloading/loading errors
- Load the GITDR filament directly into the printer using an external spool holder, bypassing AMS entirely.
- GITDR filament is hygroscopic, so it should be adequately dried prior to usage
- Use larger hardened steel nozzles recommended for ease of printing
- Print on larger models to allow the colour gradient to shift
- Increase wall thickness and infill
- Increase retraction distance to combat stringing, which is common with these filaments.

Print Parameters
PLA Glow in the Dark Rainbow prints at standard PLA temperatures, but the phosphorescent pigment is abrasive. Use a hardened steel nozzle (a 0.6 mm nozzle makes printing easier) and feed it from an external spool holder rather than the AMS. Set up this way, it offers good adhesion, smooth extrusion and consistent colour transitions across every layer.
For best results, follow the recommended print parameters provided below to achieve reliable, high-quality prints every time.

Mechanical Properties
Mechanically, GITDR provides moderate strength and rigidity, ideal for light duty or decorative applications. The addition of glow and colour pigments slightly reduces impact resistance compared to PLA+, but it also maintains solid layer bonding and structural integrity for non-load-bearing prints.
