Precision-engineered replacement nozzle and Ti-alloy heat break for 3D printer extruders, built for longer life, consistent melt performance, and broad filament compatibility. Key benefits - Longer service life: Hardened steel nozzle (SKD11) with a MOHS hardness of 7.8 resists wear from abrasive filaments and delivers up to six times the lifespan of standard nozzles. - Consistent melt and flow: A CuCrZr copper alloy section with thermal conductivity of 330 W/m·K ensures even heat distribution in the melt zone, improving filament melting and reducing extrusion inconsistencies. - Reduced heat creep: The Ti-alloy heat break lowers thermal conductivity between heater block and cold end, helping maintain a sharper thermal transition for flexible and temperature-sensitive filaments. - Smooth internal flow path: Precisely machined internal surfaces with low surface roughness (RA) reduce filament hang-ups and improve flow stability and print quality. Features and materials - Nozzle material: Hardened steel (SKD11) — durable and wear-resistant for prolonged use with abrasive and composite filaments. - Heat break: Ti-alloy heat break to minimize unwanted heat transfer along the filament path. - Thermal management: CuCrZr copper alloy for high thermal conductivity in the hot zone (330 W/m·K) to promote uniform heating. - Supported filaments: PLA, ABS, PETG, TPU, PP, PC and carbon-fiber blends including PLA-CF, PA-CF, PET-CF. Performance advantages - Better surface finish and dimensional accuracy thanks to uniform heating and smooth internal walls. - Fewer clogs and reduced rework from stable melt conditions and minimized heat creep. - Lower maintenance frequency because the hardened nozzle resists wear from abrasive additives and carbon fibers. Practical applications - High-volume or long-duration prints using carbon-fiber reinforced filaments (PLA-CF, PA-CF, PET-CF): reduced nozzle wear means fewer replacements and more consistent results. - Flexible or low-temperature filaments (TPU, PP): Ti heat break reduces heat soak and helps prevent jams or deformation in the cold end. - Functional prototyping and end-use parts in ABS, PETG, or PC: improved melt control yields stronger interlayer bonding and more reliable prints. Compatibility and use - Designed as a replacement extruder nozzle and integrated heat break solution for standard 3D printer hotend setups. Materials and thermal properties are selected to balance wear resistance, thermal conduction in the hot zone, and thermal isolation above the melt zone. What this solves - Extends nozzle life for abrasive and composite filaments, reduces print failures caused by uneven heating or heat creep, and improves overall print consistency across a wide range of materials.
