Features: High Thermal Conductivity & Uniform Heating: The cylindrical ceramic heating ring improves heating efficiency and reduces heat loss. Uniform heating and fast heat transfer, it only takes 40 seconds to heat from room temperature to 200. Available up to 300 high temperature printing. Bi-metal Heat Break & High Temperature Resistance: The heat break is made of titanium and copper alloys which supports high temperature printing at 300C and is compatible with more filaments. Also, the O.2mm thin wall thickness for excellent thermal insulation (Compatible filaments: PLA, ABS, PETG, TPU, PP, PC, Nylon, PEEK, PEI, etc.) Strength Upgrade: The heat break and heat sink are perfectly fit through the titanium alloy base to avoid pressure between them, and the strength is upgraded to extend the life of the hotend. Structural Upgrade: The heat sink size is 30% larger than the general hotend, improving heat dissipation efficiency and ensuring smooth feeding. Better Printing Performance: High-quality hardened steel nozzle, and roughness of Ra0.25 on the inner wall of the nozzle and heat break to improve print quality. Wide Compatibility: Compatible with Creality Ender-3/ Ender-5 series/CR-10/ CR-10S/Ender-2 printer. Modular standard interface design, ready to use without printing the fan shroud. Specification: Model: Spider Speedy Ceramic Hotend Nozzle: hardened steel nozzle 0.4mm*1; copper alloy nozzle 0.8*1 Product Size: 51x22x18mm Weight: 40g Color: Red and Black Competible: PLA, ABS, PETG, TPU, PP, PC, Nylon, PEEK, PEI, etc Retraction Distance: Max 5mm (can be adjusted according to the printing situation) Maximum Flow Rate: 32mm/s Package Size: 86.5x53x47.5mm/3.4x2x1.8in Package Weight: 150g/5.2oz Packing List: 1 x Spider Speedy Ceramic Hotend Kit
