Features: Wide Adaptability -It can print most 2.85mm flexible filaments on the market, such as TPR, TPU, etc, suitable for all models installed with sprite extruder such as Ender-3/Ender-3 Pro/Ender-3 MAX/Ender-3 V2. Matched with a 0.8mm large aperture nozzle it greatly shortens the printing time and improves the efficiency of product molding. Dual-gear feeding, Stable Printing - The dual-gear bite structure does not damage the filaments and ensures more reliable and stable feeding during printing. And 3.5:1 gear reduction ratio for high torque output and smooth feeding. Efficient Heat Dissipation - Through computational fluid dynamics simulation and dual-fan design, the heat dissipation function is powerful. The model molding is more stable. Full-metal Design - Aluminum alloy material Heating block helps fast to heat up and melting of filaments. And high-quality aluminum heat sink with a dense tooth design, better heat dissipation effect when attached to the surface of the tube. Compact Size with Tremendous Power - It weighs 288g,only 54x50x64.3mm. The extruder and nozzle are perfectly combined for a more powerful function.
