HELLO3D PLA Light Change – White → Blue

Filament with UV photochromic effect for original, interactive 3D prints. In its basic state, it is white (natural); when exposed to solar/UV radiation, it quickly colors to blue and returns back after the UV component recedes. The "PLA Light Change" series is officially in the HELLO3D manufacturer's offer, the "White_To_Blue" variant is commonly available at retailers.

How it works

Special photochromic additives in the PLA react to UV light – the color changes and the effect is reversible. At the same time, it prints just as easily as standard PLA.

Key features

• Changes color from white to blue in the sun/UV, fast and repeatable change.
• Easy to print like regular PLA; recommended nozzle temperature 190–220 °C.
• Diameter accuracy ±0.02 mm for reliable feeding and clean details.
• 1 kg spool for longer printing without frequent material changes.

Recommended print settings

• Nozzle: 190–220 °C
• Bed: 0–50 °C
• Speed: 50–110 mm/s Values are based on distributor recommendations for the HELLO3D Light/UV Change series. Adjust according to your printer and model.

Tips for the best result

• The effect is more pronounced under stronger UV (direct sunlight).
• Store in a dry place; protect from unnecessarily long exposure to direct sunlight so that the material maintains its properties as long as possible.

Typical uses

• Outdoor accessories, charms, educational tools, decorations, and gifts that "come to life" in the sun.
