3D pen Riff RF-3DPEN2-VI LCD for Kids, 1.75 mm filament, supports ABS and PLA

Riff Fantasi 3D Compact 3D Print Idea Pen (model RF-3DPEN2-VI) in purple is a handheld filament pen for freehand 3D drawing and small creative projects. The pen accepts 1.75 mm ABS and PLA filaments and is powered via an AC adapter (DC 5V / 2A). An LCD shows working status, temperature and warnings. The set includes the pen, an AC adapter, a stand and a 5 m test PLA filament (three mixed colors). The device is EN71 certified and is intended for hobby, educational and introductory 3D printing use.

Advantages

The pen offers adjustable print speed, automated play/pause control and a 0.7 mm nozzle for precise lines. Low-melting operation and a clear LCD make temperature and speed easy to monitor. Compatibility with common 1.75 mm ABS and PLA filaments provides flexibility for different materials and effects. The compact design and included accessories allow quick start-up straight from the box.

Suitable for

• Children's creative play and developing spatial imagination

How to use

Connect the AC adapter to a power outlet, insert a compatible 1.75 mm filament (PLA or ABS) into the feed, and wait for the LCD to indicate the set temperature. Adjust the temperature and print speed as needed via the controls, then use the Play/Pause button to start or pause extrusion. Guide the pen slowly to form outlines or build up layers for three-dimensional shapes. For PLA use lower temperatures (160–210 °C); for ABS use higher temperatures (210–235 °C). Follow visual cues on the LCD for warnings and working status.

Usage recommendations

Use under adult supervision for children. Start with the supplied PLA test filament to learn temperature and speed settings. Work on a heat-resistant surface and use the stand when the pen is idle. Store compatible ABS/PLA filaments dry and avoid mixing unknown materials. For more detailed operation and creative techniques, consult manufacturer videos and guides.
