Bimetal Heatbreak for Anycubic Kobra S1: all-metal throat up to 320 °C

Bimetal heatbreak — the hotend throat for the Anycubic Kobra S1 and Kobra S1 Max. It is built from two materials, a copper section and TC4 titanium alloy, which improves thermal isolation between the heater block and the cooling block. The all-metal design has no PTFE liner and withstands temperatures above 320 °C, while the stock PTFE-lined throat is rated to about 260 °C. The inner channel is polished for 1.75 mm filament. Note: this heatbreak is not compatible with the ceramic hotend.
