AMOLEN's glow TPU is flexible and phosphorescent — and it glows in its own base color, not a generic blue-white. Red glows red. Green glows green. The phosphorescent particles charge under UV or ambient light and emit in the hue of the filament itself. At 95A shore hardness, the material stretches to three times its original length and returns to shape, making it the right choice for wearable components, flexible cosplay armor, phone cases, gaskets, grip elements, and functional flex parts that also need to be visible after dark. Print temperature runs 190–220°C with bed temperature optional at 0–60°C.
Available colorways:
Red — warm red in daylight with a red-toned phosphorescent glow. Strong contrast in dark environments.
Yellow — bright warm yellow in daylight; yellow-toned glow emission with high visibility in dark settings.
Orange — warm orange in daylight; amber-orange glow output, good for high-visibility applications.
Green — vivid green in daylight; the strongest glow output of the single-color options, with the most intense and longest-lasting phosphorescent green emission.
Blue — medium blue in daylight; cool blue glow emission.
Rainbow Purple Pink Orange Blue — multicolor variant; the strand transitions through purple, pink, orange, and blue tones, producing a varied daylight appearance and a multi-hue glow pattern.
Technical specifications:
Diameter: 1.75mm ±0.02mm
Print temperature: 190–220°C
Bed temperature: 0–60°C (bed optional)
Shore hardness: 95A
Elongation at break: 3x (stretches to 300% of original length)
Material: TPU (thermoplastic polyurethane) — NOT a PLA material. Print settings, temperatures, and handling differ from any PLA product in this catalog.
Glow mechanism: Phosphorescent particles embedded in the TPU base; glows in its original color — Red glows red, Green glows green. Charges under UV or ambient light.
Print speed: Slower print speeds required compared to PLA — reduce feed rate and increase retraction settings. Direct drive extruder recommended; Bowden setups are compatible but may require additional tuning to avoid under-extrusion.
Vacuum sealed: Yes — moisture protection for storage
Spool weight: 1KG (2.2LB)
Nozzle: Standard 0.4mm brass compatible
🌵 Why Buy from VectorDesignsArizona?
We run a large and growing 3D print farm out of Tucson, Arizona and the filaments we carry are the ones loaded in our own machines. As an authorized reseller, we only sell what we've personally used and relied on. Every material in our store has been tested in real production runs, not just sampled. When we recommend a filament, it's not a sales pitch, it's what's actually running through our printers right now.
