3Dsimo Filament ABS Thermochrome Blue→White 5 m

3Dsimo Filament ABS Thermochrome Blue→White 5 m is a thermochromic ABS filament formulated for compatible 3D pens and small-format 3D printers that accept ABS. The material displays a reversible color change from blue to white in response to temperature variations, enabling visible thermal indication on printed parts while retaining ABS mechanical properties. With a 5-meter length, the filament is suitable for short runs, prototypes, small repairs and decorative elements where temperature-sensitive appearance is required.

Advantages

The filament combines standard ABS strength, dimensional stability and ease of post-processing with a reliable thermochromic pigment that shifts color from blue to white at a defined temperature range. Its formulation allows extrusion through pens and compact printers compatible with ABS, delivering consistent layer adhesion and surface finish suitable for functional and aesthetic applications. The reversible color change requires no electronics and provides a clear visual cue of temperature exposure.

Suitable for

• Quick prototyping and concept models with visible thermal feedback
• Small repairs of ABS parts where color-change is useful
• Educational demonstrations of thermochromic effects and material behavior
• Decorative detailing on small objects, wearables or gadgets

Key specifications

• Material: ABS with thermochromic pigment
• Color change: blue to white with temperature variation
• Length: 5 meters
• Form: filament suitable for compatible 3D pens and small-format ABS printers
• Properties: good layer adhesion, machinable and post-processable like standard ABS

How to use

Load the filament into a 3D pen or a small-format 3D printer that supports ABS filament. Use printing temperatures and settings appropriate for ABS on your device; ensure the hotend or pen reaches temperatures suitable for ABS extrusion and follow manufacturer guidance for extrusion speed and layer height. Allow printed parts to cool naturally; the thermochromic effect will be visible as the part temperature crosses the pigment activation threshold. When performing post-processing such as sanding or solvent smoothing, be aware that high heat or aggressive solvents may affect the thermochromic pigment.

Usage recommendations

Store the filament in a dry, cool environment away from direct sunlight and excessive heat to preserve thermochromic performance. For best results, use filament within manufacturer-recommended temperature ranges and avoid prolonged exposure to temperatures beyond those tolerable for ABS and the thermochromic additive.
