1. Pick the best Heatbreak for your 3D Printer that Doesn't Leak, No Clogging. 2. Advantages: The all metal heat break works well with high-temp filaments. There is no Teflonn to wear or burn, high temperature resistance up to 500℃. High performance titanium alloy heatbreak,has excellent heat insulation and thermal conductivity，the metal doesn't get hot too quickly, it also dissapates heat quickly too. Polished Titanium Heatbreak prevents hotend clogs caused by heat creep,ensure printing smooth. 3. HIGH QUALITY PROCESS TECHNOLOGY: Premium CNC precision technology, mirror smooth bore, clean cut threads, The insides are polished and well machined and filament fits tightly and has a smooth path of travel. Integrated design refused to jamming, improve printing efficiency.
