Feature: 1. HARD MATERIALS: 3D printer nozzle uses high strength hardness alloy, the tip is much harder than other nozzle tip materials, providing first class durability and wearproof filaments 2. LEAKAGE AND CLOGGING PROOF DESIGN: The extruder nozzle is seamlessly connected to the throat to prevent filaments from leaking or clogging, more trusted 3. EXCELLENT PERFORMANCE: 3D printer nozzle can prevent high temperature, possess good thermal conductivity, high wearing feature. Pipe inner wall roughness Ra<0.4, reduce clogging 4. PRINTABLE MATERIALS: 3D printer nozzle tip with material upgrade, support a variety of consumables printing: PLA, ABS, PETG, PTU, PP, PC, very versatile 5. APPLICABLE MODEL: Hardened 3D printer nozzle is very versatile for Raise3D N series, Pro2 series, Pro3, E2 series, Ni plated for good conductivity Specification: Item Type: 3D Printer Nozzle Size: M6 x approx. 13.8mm / 0.54in Material: Alloy and Ni plating Pipe Inner Wall Roughness: Ra<0.4, reduce clogging Support Printing Consumable: PLA, ABS, PETG, PTU, PP, PC and other materials. Package List: 1 x 3D Printer Nozzle
