Beelayers TPU Glow-in-Blue Filament is a unique thermoplastic polyurethane (TPU) 3D printing filament that combines flexibility, strength, and a glow-in-the-dark effect for creative and functional applications. TPU is a flexible elastomer prized for its rubber-like elasticity, excellent abrasion resistance, and strong layer adhesion.

Glow-in-the-dark filaments contain phosphorescent additives that absorb light and re-emit it as a visible glow in dark environments. To achieve the best glow effect, prints made with glow filament should be exposed to bright light or UV light before viewing them in darkness. The glow brightness and duration depend on how much light they absorb.

This TPU Glow-in-Blue filament delivers strong flexibility with a glowing blue effect after exposure to light, making it perfect for specialty projects, decorative items, wearables, creative tools, night lighting accents, and unique prototypes. Its flexibility also supports functional parts that require impact resistance, stretch, and recovery.

Key Features & Benefits

• Glow-in-Blue Effect – absorbs light and emits a visible blue glow in the dark

• Flexible & Durable TPU Material – rubber-like elasticity and impact resistance

• Strong Layer Adhesion – excellent interlayer bonding for lasting prints

• Vibrant & Functional – ideal for creative, decorative, and flexible applications

• Moisture & Chemical Resistance – TPU resists moisture and many chemicals better than PLA/ABS

Technical Specifications

Recommended Printing Settings

• Nozzle Temperature: 200–230°C

• Bed Temperature: 30–60°C

• Printing Speed: 15–40 mm/s (slower speeds improve flexibility control)

• Retraction: Low retraction to reduce stringing

• Cooling: Moderate after first few layers

Printing Tips

• Dry the filament before printing to prevent moisture absorption

• Use a direct drive extruder or low-pressure Bowden setup for best soft filament control

• Slow down print speed for smoother TPU prints with fewer artifacts

• After printing, expose the part to a bright light or UV flashlight for maximum glow effect

Ideal Applications

• Glow-in-the-dark toys and decorations

• Flexible wearables, grips, and bands

• Night lights and glow accents

• Creative prototypes and flexible parts

• Impact-resistant functional prints
