How does the photochromic effect work?
Photochromic additives in the PLA react to UV light: the print deepens in tone under sunlight and gradually returns to its lighter shade indoors. Strength varies with UV intensity.

Frequently Asked Questions
How does the photochromic effect work?
Photochromic additives in the PLA react to UV light: the print deepens in tone under sunlight and gradually returns to its lighter shade indoors. Strength varies with UV intensity.
Is it compatible with regular FDM printers?
Yes, it is compatible with mainstream FDM printers taking 1.75mm filament; standard PLA settings and slicing workflows apply.
What temperature should I print at?
Our PLA parameter sheet lists 190-220C. Start mid-range and adjust in small steps for surface finish; avoid overcooking, which dulls the color-change response.
How much can one spool print?
Slice your models, sum the filament-length estimates at your wall count and infill, and compare the total against the spool's length.
Does the effect fade over time?
The response is repeatable but can weaken with very long UV exposure; store finished pieces out of direct sun when not displayed, like most photochromic products.
What model-making projects show the effect?
Sun-exposed dioramas, outdoor scene bases, kids' demonstration models and novelty desk pieces where the indoor-outdoor color shift is the hook.
How is it packed and stored?
Vacuum sealed with desiccant and boxed; keep sealed until printing and store finished prints away from continuous strong UV to preserve response.
