Special and exotic filaments are materials with unique properties or special effects: glow-in-the-dark, thermochromic, magnetic, magnetizable, touch-conductive, marble, granite, ceramic, and other unique filaments that do not fall into standard categories. At Strato3D, we select the most interesting references for those who want to print truly original objects.
Typical special materials
- Glow in the Dark (luminescent): absorb light and glow in the dark for hours.
- Thermochromic: change color with temperature (hot/cold).
- Magnetic (Magnetite): contain magnetizable ferrous particles.
- Marble and stone effect: aesthetic of marble, granite, limestone.
- Pearl effect: iridescent with mother-of-pearl reflections.
- Tungsten (PETG Tungsten 75%): very high density for shielding, balancing.
- Breakaway support: mechanically removable supports with a premium finish.
Technical features
Print parameters vary significantly depending on the base material (PLA, PETG, ABS). Always check the specific product's technical data sheet.
- Recommended nozzle: for most of these materials (marble, magnetite, tungsten), a hardened steel nozzle ≥0.5 mm is required.
- Speed: reduced by 20-30% compared to the base material.
- Effects: often more visible at specific nozzle temperatures.

Frequently asked questions
Is Glow in the Dark really bright? Yes, but it needs to be "charged" with an intense light for a few minutes. It then glows for 30-60 minutes with progressively less intensity.
Do thermochromics last? The effect is permanent — the filament reversibly changes color every time the temperature varies.
Can I print them with a consumer printer? Almost all of them yes, but with a hardened steel nozzle for materials with mineral or metallic fillers.
What is PETG Tungsten used for? Very high density (4-5 g/cm³): balancing, X-ray shielding, weight simulators, scales.
