On the other hand, these extruders come with better mounting solutions for part cooling which is important on filaments like PLA, TPU and even PETG. With the E3D Hemera, you get an all-metal heat break but the extruder is bulky and heavier compared to the other two. The BIQU H2 offers similar features, but it comes with a PTFE lined heat break and you need to purchase a bi-metal heat break separately if you plan to use it with high temperature materials. The filament loading lever is a nice addition that I hope to see implemented in other extruders in the future. When it comes to printing performance, it’s one of the best you can get right now, because of its low weight, short filament path and integrated heatsink. The NF Sunrise is not a cheap extruder, and it’s in the same price range with other high-performance extruders available on the market so I think it’s only fair to do a small comparison. When done, you just close the lever and start printing.Ĭonclusions: Is the Mellow NF Sunrise worth it? When raising the lever, the idler gear is pushed against the spring allowing the filament to get inserted in the extruder. It’s also worth mentioning that the NF Sunrise has a metallic lever which helps with loading filament. I also like that the stepper motor comes with a detachable cable which is handy when doing wire management of your printer. We get the LDO-36STH20-1004AHG(MLW) 36mm pancake stepper motor which can handle higher voltage without overheating.

The NF Sunrise extruder has dedicated mounting holes in the back, making it compatible with Creality machines that use the generic Creality hotend (ex: Ender 3).

The first version of the Mellow NF Surise had an issue with the alignment of the filament path and the gears, but this issue was fixed now. But the main benefit of the NF Sunrise extruder is the all-metal design which allows the extruder to also act as a heatsink. The Mellow NF Sunrise extruder uses a pair of Bondtech gears put in motion by a 36mm pancake stepper motor, similar to what you would get on a Sherpa Mini.
