Spectrum 3D Filament PLA Thermoactive 1.75 mm Red 1 kg (80172)

Artists and educators can create interactive models that change color with temperature using this Spectrum PLA Thermoactive filament. The red filament transitions to a different shade when exposed to heat, adding a dynamic element to decorative prints and educational demonstrations. With a diameter of 1.75 mm and a tolerance of ±0.03 mm, it ensures consistent extrusion and reliable layer adhesion on FDM 3D printers.

Why choose it

The thermoactive property allows prints to respond to temperature changes, making them engaging for teaching and artistic expression. PLA is easy to print with low warping and low odor, suitable for home and classroom environments. The spool is made from recycled plastic, aligning with eco-conscious practices.

Ideal use cases

• Decorative prints that change color with heat
• Educational models demonstrating thermal properties
• Prototypes requiring visual temperature indicators
• Artistic projects with interactive elements

Good to know

The filament is vacuum-sealed with desiccant to maintain dryness and prevent moisture absorption. It is compatible with standard FDM 3D printers that accept 1.75 mm filament. Store in a cool, dry place when not in use.
