The nozzle of the high-flow HF integrated hot end is made of hardened steel and has an integrated design, which increases the maximum volume speed by 60%. The optimization of the melting zone significantly increases the volume speed of the high-flow hot end, with a maximum volume speed increase of 62.5%. Its printing speed is much faster than that of the standard flow hot end, which can shorten the model printing time by up to 30%. Under the same model design and printing parameters, the larger the model, the more time you save-especially for models with large area filling. The high-flow hot end can significantly reduce the lack of material caused by insufficient extrusion and optimize the originally rough model . With high and stable flow, the high-flow hot end can that each print presents perfect printing details, and has edges and smooth surfaces like ordinary flow . The speed is upgraded, but the printing effect is no less. Quickly replace the hot end, the nozzle is designed in an integrated manner, leak-proof and anti-clogging. The magnetic block on the hot end heating component can quickly and accurately fix the nozzle to the installation position, making it easy and convenient to remove and install the nozzle. High hardness, smooth inner wall, no plugging.
