3D Pen Riff Fantasy RF-3DPEN2-BL with LCD, 1.75 mm ABS/PLA Filament, 0.7 mm Nozzle, AC Powered, Adjustable Temp and Speed

The Riff Fantasi 3D RF-3DPEN2-BL is an AC-powered 3D printing pen with an LCD display designed for creative drawing, quick prototyping and educational use. It accepts 1.75 mm PLA or ABS filament and is supplied with an AC adapter, a stand and a small set of test PLA filament in three colors. The pen features an adjustable temperature range and printable speed controls, a 0.7 mm nozzle and an automatic play/pause function for controlled extrusion.

Advantages

The pen offers temperature and speed adjustment shown on an LCD for clearer control over extrusion. Low melting operation and a compact design make it suitable for supervised use by older children and hobbyists. It is compatible with common 1.75 mm PLA and ABS filaments and includes a starter filament and accessories for immediate use.

Suitable for

• Creative drawing and 3D doodling for hobbyists and children (with supervision)
• Simple prototyping and model repairs
• Educational projects for learning basic 3D shaping and spatial skills
• Gifts for hobby artists, students and craft enthusiasts

When it may not be suitable

This pen is not a replacement for a full-sized 3D printer when high precision, large-scale prints or industrial-strength materials are required. Although the device has safety-minded features and a relatively low melting point, young children should use it only under adult supervision due to hot nozzle temperatures when operating at higher settings.

Key specifications

• Nozzle diameter: 0.7 mm
• Filament diameter: 1.75 mm (PLA/ABS compatible)
• Temperature range: PLA 160–210 °C, ABS 210–235 °C
• Power supply: DC 5 V / 2 A (AC adapter included)
• Controls: adjustable print speed, automated play/pause
• Display: LCD for temperature, speed and warnings
• Safety: relatively low melting operation quoted at 50–60 °C for specific components (refer to manufacturer guidance)

How to use

Connect the pen to the supplied AC adapter and power outlet, then load a compatible 1.75 mm PLA or ABS filament. Use the LCD to set the desired temperature and wait for the pen to reach the set temperature. Feed the filament through the loading mechanism and use the speed controls or play/pause button to start and pause extrusion. Work on a stable surface and use the included stand to hold the pen when not in use. Follow manufacturer instructions and safety videos for proper threading and operation.

What to consider before purchase

• Requires 1.75 mm PLA or ABS filament (not all filament types are identical; check compatibility)
• Operates from an AC adapter (DC 5 V / 2 A) — ensure access to a compatible power outlet
• Intended for small-scale creative work; not suited for industrial printing tasks
• Supervision recommended for children due to hot nozzle during use

Usage recommendations

For best results, start with the supplied PLA test filament, practice on a flat surface, use moderate temperature and speed settings, and consult instructional videos for filament loading and safe handling.
