Fast Heat Dissipation - No need of bowden tube, filaments directly pass through the smooth inner wall of aluminum heatsink, which allows for faster heat dissipation.

Efficient Heat-blocking - Heat break is made of Titanium Alloy, providing much better thermal isolation than normal stainless steel printer throat.

High Precision - Due to quality-first production process, the heatsink, heater block and nozzle could offer smooth inner wall and precise connection.

No blockage - Because of the advanced heatsink and heat break, the probability of the filament blocking the hotend is greatly reduced.
