3D filaments: special PLA
Special PLA filaments for all FDM 3D printers: heat sensitive, reinforced PLA, photosensitive PLA, phosphorescent PLA.
Heat sensitive filament
Heat sensitive filaments change color depending on the temperature they are exposed to. Most of these 3D printing materials change color from 29°C. Depending on the exposure, the color changes more or less, this type of filament returns to its original color when the temperature is lower (if cooled for example with air or water).
The phosphorescent filament for 3D printers reacts to light. It retains its natural tint in the light, but changes color in the dark (usually to green or blue). The hue and brilliance greatly depend on the time of exposure to light and the shape of the printed object.
The photosensitive threads react to UV rays. These materials change color according to the degree of exposure to light. A conventional UV laser can change the color of 3D printed prototypes - a new field of application for 3D printing.
In this category there are many other types of special PLA, find the one that best suits your needs!
