Features: Brand new and high quality Treated with highly-temperatures carburizing and hardening, and have super wear resistance, heat resistance, highly hardness and highly toughness. Two characteristics, long service life, and suitable for most printing materials on market. Use hardened steeL surfaces coating. It have super hardness and excellent conductivity. highly thermally performances, keep the nozzles tip temperature uniform during the printing process, thereby ensuring stable extrusion. Since nozzles typically have very highly thermally property, printing speed can be furthers increased without sacrificing quality. From traditional printing to reinforced materials, nozzles can easily handle long printing periods on any material. Specifications: Material:ABS Length:Approx.110mm/4.33inch Package Includes: 1x Thermometer Line note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
