Spectrum Filaments’ Thermoactive Red PLA is a specialized filament designed for 3D printing applications that require a visual response to temperature changes. The filament transitions from red to cream when heated above 30°C, and vice versa. This feature is particularly useful for educational models, objects like mugs or thermoses that interact with heat, and any project requiring a temperature-responsive element.
