3Doodler Filament FLOW 20 PLA 20 Colors Refill Pack Polylactic Acid

The 3Doodler Filament FLOW 20 PLA 20 Colors Refill Pack contains twenty polylactic acid (PLA) filaments in a broad range of colors designed for use with 3Doodler Flow pens and other devices compatible with 1.75 mm PLA. The set provides compact, ready-to-use spools that let users experiment with color and form while using an eco-friendly, RoHS-certified material. Each spool length and the operating range suit freehand 3D drawing and small decorative projects.

Advantages

The filaments are made from polylactic acid (PLA), a biodegradable thermoplastic derived from renewable resources, offering ease of use and low-warp printing characteristics suitable for handheld 3D pens. The pack includes twenty distinct colors to support multicolor designs without frequent repurchasing. RoHS certification ensures the material meets safety and environmental standards. The filaments are compatible with 1.75 mm feeding systems and the recommended operating temperature supports consistent flow and reliable extrusion when used within the specified temperature range.

Suitable for

• Freehand 3D drawing and sculpting with 3Doodler Flow pens
• Creating small decorative objects, models, and prototypes
• Multicolor repairs, accents, and custom trims on craft projects
• Educational activities that teach basic 3D modeling and material handling

How to use

Load a 1.75 mm PLA filament spool into a compatible 3Doodler Flow pen or other 1.75 mm feeder following the device manufacturer’s loading instructions. Set the pen or printer to the recommended PLA operating temperature range, typically 180–190 °C, allow the tool to warm up fully, then advance the filament until it extrudes smoothly. Use steady, controlled motions for freehand drawing or switch between colors by retracting the current filament and loading a new spool. Follow the pen’s cooldown and unloading procedure before changing materials.

Usage recommendations

Store filaments in a dry, dust-free environment and avoid prolonged exposure to direct sunlight to preserve material quality. Use the recommended temperature range and compatible 1.75 mm feeding systems for best extrusion performance. When switching colors, ensure the previous filament is fully retracted and extruded clear before starting a new color to prevent cross-contamination.
