Here, we promise that this is a genuinely high-flow hot end, meticulously developed by our JUUPINE team specifically for the H2D printer (multiple tests have shown that its flow rate even surpasses that of the original high-flow hot end). Upon receiving the product, please be sure to follow the usage instructions provided on our product detail page to avoid nozzle blockage caused by excessively high flow rates during operation.

In addition, we have specially adopted a nano-coating process on the nozzle, enhancing the wear resistance of this hot end by 2.5 times compared to the original one.

We always prioritize customer satisfaction above all else. If you encounter any dissatisfaction after receiving and using the product, we will unconditionally offer you a refund or exchange service.
