3Dsimo thermochrome refill white G3D3017 — thermochromic filament insert for 3Dsimo pens

3Dsimo thermochrome refill white G3D3017 is a thermochromic filament insert designed for compatible 3Dsimo drawing and crafting pens. The white thermochromic insert changes color with temperature, enabling visible heat-sensitive accents and functional indicators for prototypes, models, and craft projects. The refill is intended to work as an interchangeable material element for 3Dsimo pens that accept filament inserts and provides a practical way to add temperature-dependent visual effects during hand-drawn or pen-extruded work.

Advantages

The thermochromic insert offers temperature-dependent color change in a compact refill format suitable for handheld pen tools. Its white base provides neutral visibility at room temperature and predictable contrast when the material reacts to heat. As an insert for 3Dsimo pens, it allows quick swapping between standard and thermochromic materials without changing the tool. The product is intended for decorative detailing, rapid prototyping with visual temperature feedback, and small-scale functional indicators where simple thermal response is required.

Suitable for

• Decorative accents on models, miniatures, and craft items
• Prototyping parts that require visible temperature response
• Educational demonstrations of heat-sensitive materials
• Small functional indicators for basic thermal changes in projects

Key specifications

• Material type: thermochromic filament insert formulated for pen extrusion
• Base color at ambient temperature: white
• Color-changing property: temperature-activated thermochromic effect
• Compatibility: designed for use with compatible 3Dsimo drawing and crafting pens that accept filament inserts
• Form factor: refill/insert suitable for handheld pen tools

How to use

Install the thermochromic refill according to the instructions for your compatible 3Dsimo pen, ensuring the pen is powered off when inserting or removing the insert. Use the pen at the recommended operating temperature and draw or extrude the material in the same way as standard refills. Allow applied material to cool to ambient temperature to observe the base (white) appearance, and apply heat locally to observe the thermochromic color change. For best results, test on scrap material first to confirm the visual effect and extrusion settings.

Usage recommendations

Store the refill in a cool, dry place away from direct sunlight to preserve thermochromic properties. Avoid prolonged exposure to high temperatures when not in use to reduce premature activation of the color-change effect. When using the insert, follow standard safety precautions for handheld heating tools and ensure adequate ventilation during prolonged operation.
