Bi-metal Material Heatbreak: The Ender 3 heat break is made of Titanium Alloy and Copper .Titanium alloy is used to reduce heat conduction upward from the heating block, and gold-plated copper is used to dissipate heat to accelerate heat conduction
4.1 Bore Style: The straight through bore of 4.1mmmakes the filaments will not face any gaps after extrusion.It can minimize the possibility of clogging,thus helping to print flexible filaments
High Temperature Resistance: All metal heat heatbreak works well with high temperature filament. High temperature resistance up to 450-500 ℃, flexible wire PLA and other wire printing temperature is lower than 250℃
Applicable Models: The titanium alloy and copper heatbreak is compatible with Ender 3 V2, Ender 3 Pro, Ender 3 CR10 series 3D printer hotend
