A 1 kg (2.2 lb) reel of 1.75 mm Temperature Change (Blue to White) ABS (acrylonitrile butadiene styrene) filament for 3D printing. This thermochromic filament transitions from blue to white as it warms, creating dynamic, colour-shifting prints that respond to touch, ambient temperature, or warm liquids.

ABS is one of the most widely used 3D printing materials, valued for its strength, durability, and good print quality. Printed parts can be sanded smooth or vapour-smoothed with acetone for a glossy finish that also strengthens layer adhesion. The filament ships vacuum-sealed on a heavy-duty plastic reel to keep out moisture.
