Integrated all-metal extruder nozzle and heat break designed for fast removal, easy replacement, and reliable printing. Compatible with popular 3D printers including K2 Plus and HI-Model. Key benefits — why you need it - Reduced maintenance and faster setup: fully integrated nozzle + heat break design allows quick disassembly and swap of parts, saving time when changing materials or servicing the hotend. - Broad filament compatibility: engineered to print everything from standard plastics to abrasive composites without frequent nozzle changes. - Longer lifetime and consistent flow: hardened materials and precision internal finishing reduce clogs, filament leakage and wear so prints stay reliable over time. What makes it stand out (features) - Integrated all-metal construction: nozzle and heat break form a single, serviceable assembly for cleaner connections and simpler maintenance. - Ti-alloy heat break: lower thermal conductivity to improve thermal separation between hot and cold zones and reduce heat creep for better retraction and print quality. - Hardened steel nozzle (SKD11) with CuCrZr components: durable contact materials that support abrasive filaments while maintaining thermal performance. - Exceptional wear resistance: SKD11 hardened steel with a Mohs hardness of 7.8 delivers up to six times the service life of standard nozzles. - Smooth internal flow path: inner wall surface finished to Ra < 0.4 to promote uninterrupted filament flow and minimize clogging. - Tight, leak-resistant fits: precision machining prevents filament leakage during high-speed or high-temperature printing. Compatibility and supported materials - Compatible with K2 Plus and HI-Model printers (and other machines using the same interface). - Supports a wide range of filaments: PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, PET-CF. Performance and reliability - Designed for stable high-temperature performance and reduced heat transfer into the cold zone. - Durable against abrasive carbon-fiber and glass-filled filaments thanks to hardened steel construction. - Smooth internal finish and precision joints reduce stringing, blobs and blockages for higher print quality. Typical use scenarios - Printing abrasive composite parts: Ideal for repeated use with PLA-CF, PA-CF, or PET-CF where hardened steel resists rapid wear. - Flexible or precision prints: TPU and small-layer prints benefit from the Ti-alloy heat break and Ra < 0.4 internal finish for consistent filament flow and fewer clogs. - Engineering thermoplastics: Reliable high-temperature printing of PC, PP, or ABS with improved thermal separation and leak-resistant connections. Materials and specifications (as provided) - Heat break: Ti-alloy for reduced thermal conductivity. - Nozzle: Hardened steel (SKD11), Mohs hardness 7.8; CuCrZr components included. - Inner surface roughness: Ra < 0.4. - Compatibility: K2 Plus, HI-Model. This nozzle assembly delivers easier maintenance, broader material support, and significantly longer life while maintaining precise, clog-resistant extrusion for consistent print results.
