【All-Metal Heatbreak】Made of harder and more wear-resistant materials, this all-metal heatbreak works well with high-temperature 1.75mm filaments such as PLA, TPU, PETG, and ABS (resistance up to 300°C). 【Bimetal Design】Titanium alloy is used to reduce heat transfer from the heat block, and plated copper is used to promote heat transfer. 【Niche Processing】Compared to ordinary heatbreaks, the resistance to print retraction is significantly reduced, and therefore, the printing results are much more accurate and delicate. 【Application】Compatible with Ender-3 S1, Ender 3 S1 Plus, Ender-3 S1 Pro, and CR-10 Smart Pro.
