TimeMass Retroreflective Holographic Filament

$39.99

Light up your prints, shine like a road sign by day, glow blue like a galaxy by night.

Meet the filament that bends light to your will. TimeMass Retroreflective Holographic fuses three light-active systems in one spool: a high-crystallinity TimeMass Light base that moves light through the body of your print, retroreflective glass beads that throw light straight back at the source, and a rare-earth blue glow phosphor that stores energy and radiates in the dark. The result is a print that looks alive bright, shimmering, and otherworldly, whether you’re under sunlight, LEDs, or lights-off, but the printed shape needs to guide light, a benchy won’t do the trick.

Why you’ll love it

  • Two personalities, 24/7: Flashlight or headlights on it? It “pops” back at you like a safety sign. Lights off? It emits a deep, electric-blue glow, no batteries needed.

  • Built-in light piping: Our high-crystallinity TimeMass Light matrix transports and diffuses light through walls and edges, so pieces feel like they’re lit from within.

  • Holographic shimmer: Ultra-fine prismatic microspheres scatter light into spectral colors for a subtle, shifting rainbow as you move.

  • Conversation-starting: Looks premium on a desk; turns into a showpiece at night. Perfect for gifts, commissions, signage, night-lights, jewelry, props, bike reflectors, and “how did you print that?” moments.

How it works?

  • TimeMass Light base: A clear, structured polymer matrix with tuned crystallinity lets light travel across your part, less “hot spot,” more even internal glow.

  • Retroreflective beads: Microscopic glass lenses send incoming light straight back to its source, creating that road-sign flash when viewed near the light.

  • Blue phosphor (strontium aluminate, Eu/Dy doped): “Charges” under light and re-emits blue in the dark, fading slowly over time.

What to make?

  • Cosmic décor & light art (panels, prisms, crystal clusters)

  • Reflective bike tags & outdoor accents (be seen at night)

  • Logos & signage with day “flash” + night glow

  • Jewelry & wearables with holographic shift

  • Night-lights, ornaments, suncatchers, display bases

Pro tips for best results

  • Keep it dry: Store in a dry box; if needed, dry at ~155 °F (68 °C) for 2 hours. Moisture = micro-bubbles = reduced clarity/glow.

  • Polish the light entry: Light loves a smooth window. Lightly sand/polish the flat base to help “inject” light from below.

  • Charge the glow: UV flashlight or bright lamp for 1–2 minutes. Blue emission is strongest right after charging and remains visible for hours.

  • Show-time moves: For the retroreflective effect, shine the light from near your eyes (phone LED, headlamp) and watch it beam straight back.

Safety & handling

Non-toxic ingredients; rare-earth dopants are bound in the plastic. Print in a ventilated area like any filament and avoid inhaling fumes. Finished parts are safe to handle.

To keep this filament transparent enough for proper light transmission, it must be thoroughly dried for at least 24 hours at 155°F (68°C) before printing. If the filament is not dried, moisture trapped inside will expand during extrusion, creating microbubbles that turn into internal micro-foaming an effect that dramatically reduces clarity and prevents light from traveling through the material as intended. In other words, skipping the drying step is like trying to shine a flashlight through a latte: the glow gets lost in the foam. Dry it well, and the filament performs exactly as designed clear, bright, and ready to illuminate your prints.

Important Note About Our Optical (Iridescent & Retroreflective) Filaments

Most iridescent and retroreflective filaments on the market are made with 100% infill of reflective or iridescent particles, making them fully opaque. Because light cannot penetrate these materials, the interaction between light and the filament occurs only at the surface.

TimeMass / Timeplast filaments are fundamentally different. We use an optical base material (“light filament”) and intentionally do not fill the filament 100% with retroreflective beads or iridescent pigments. This controlled formulation leaves space within the material for light to enter, travel through, and exit the printed object.

As a result, prints made with our filaments can both reflect and transmit light, enabling new types of designs such as light-guiding objects, illuminated edges, glowing volumes, and optically active structures. This approach opens the door to entirely new printing possibilities beyond surface-only visual effects.

Printing recommendations: For reliable prints, please always use a 0.8mm nozzle. A cryogrip blue plate so that first layer will adhere. For all of the other parameters, please use our specialized GPT here. And if at any point you have questions, concerns, or difficulty printing, please don’t hesitate to reach out to us at timeplast@timeplast.com. We work with every customer until their filament prints successfully, and we also offer no-questions-asked refunds if the material simply isn’t the right fit for you. Your satisfaction is always our priority.

In all honesty, with TimeMass you won’t just print objects, you’ll print experiences. Think about it. By introducing a new programmable dimension, your designs don’t just sit there. They evolve. Shift. Light up. Soap up. Grow up. Phase out. Disappear and more. You’re actually building moments.

Precision? Built In.
Making a filament with Timeplast is not easy, not at all. We can’t use automated machines for example. Each spool is handcrafted, here in the U.S. and monitored by a human for over a 49-minute cycle per spool. That’s not mass production, that’s obsessive accuracy.

Specs That Actually Matter:

  • Diameter: All of our filaments have a diameter of Ø= 1.75 ± 0.15 mm.

  • Weight: 350 gr.

  • Compatibility: Works with all major 3D printers. No drama.

True timed obsolescence
Use filaments with built-in "time codes" like Active, Delayed or Passive to make your prints transform, separate, or self-destruct on schedule. Whether it’s art, function, or straight-up sci-fi—if you can print it, you can make it move.

Water Molecular Disintegration – Print Today, Gone Tomorrow
Yes the words “Molecular Disintegration sounded like something that ChatGPT would say, but no, it’s the only way to explain how our materials dissolve in the presence of water down to a Carbon-to-carbon level. TimeMass breaks down at the molecular level when exposed to water. That’s not marketing, it’s chemistry. Smart materials that serve their purpose, then step aside. Clean, conscious, and built for next-gen applications.
