Creality Official 5pcs MK-HF Nozzle with 2pcs Sprite Extruder Silicone Sock, Copper Alloy Nozzles for Ender 3/V2/Pro/Max/Ender 3 S1/Pro/Plus/Neo Series/Ender 5 Series/Ender 6/CR-6/CR-10/Sermoon D1/V1

I bought this hot end to help with temperature stability and increasing flow through my ended 3 S1 Pro. I upgraded my S1 Pro with the Sonic Pad from Creality and flow was something needing to be upgraded to get more speed and reliability out of my machine. Highly recommend

Very straightforward swap, two screws out - two screws in. I like the higher temp heating element and the bimetallic heat break for printing more engineering materials like PET, Nylon, or even PC. I did add a bit of high temp thermal paste to the copper part of the heat break to improve the contact between the heatsink and the heat break. One point of contention I have is the way the thermistor is secured with just thermal cement unlike what is shown in the item description (2nd pic). This cement tends to degrade and crumble over time, especially for high temp/high-speed printing. Its highly likely that in the long run, the thermistor will get dislodged resulting in failed prints.

I bought this for my ender3 pro and the only problem I had was that my printer didnt save the E step value I put in as directed by the little book that comes with it. After hours of trying to figure out what the problem could be, I went through all the settings and found that it had reverted back to the original E step value. TLDR: make sure to double check ur E step value BEFORE you print!

I.HATE.CREALITY! I bought this extruder thinking a direct-drive would be less worriesome than a Bowden-style. This device was VERY poorly planned. After installing it, messing around with the cable connections to the board, then flashing the firmware...the Home X Axis command will NOT send the x-axis towards the lmit switch on the left. It constantly nudges the extruder to the RIGHT. Also....trying to Auto-Home the printer sends the X-Axis over and crashes into one of the screws that holds the wheels for the right-side of the gantry...because Creality is just plain STUPID. Dont buy ANYTHING from Creality, they are just GARBAGE!

this set comes with a great mixture of the standard (0.4mm) and some nice to have sizes for detail prints and large prints. at just over 3 dollars per nozzle, its certainly not cheap, but its also not the cheap brass stuff either, so as far as value goes, i think this is pretty good. these are premium (relatively speaking) nozzles for a premium hotend / extruder set from creality. the reality is that the MK-HF is just a variation on the MK8 nozzle, but better material. as the saying goes, in for a penny, in for a pound - if youre spending the premium for a printer with the sprite extruder, the MK-HF nozzle is a low cost component that is pretty integral to the design, and worth it, in my opinion.

Great replacement part for anyone with an Ender 3 S1 or S1 Pro. This one is a drop in replacement for the S1 Pro, and for the S1 its an upgrade due to the all-metal (bimetal) heatbreak. You get a preassembled package containing the heatblock, bi-metal heatbreak, nozzle, and silicone heat sock. Just drop it in and heat tighten and its good to go.

Clog free, no thermal runaway at 50mms with nylon carbon or PETG. Ive run 1mm nozzle at .8 layer height and IT THROWS DOWN. .8 nozzle at .5mm layer is draft quality. Best .4mm nozzle at .2mm layer is super fine for nylon and PETG. I went from an E3D V6 to this and very impressed.

I actually got this to scavenge for parts, as I needed a new heater cartridge, thermistor, heat block, and sock after my Chiron had a blowout. The heat break is a little shorter than the one for the chiron, but the lower of the two set screws for the v5 heatsink is more than enough to secure it, and the FTPE tube easily reaches the top of the break. wired everything up, changed the nozzle (the plated one from this went to my ender 3 max neo) and started printing. Have had 2 successful prints with this combo so far, and everything seems to be working great!

This Creality Official Sprite Extruder Heater Block Upgrade Kit is great! It installed without any issues at all into my Ender 3 S1 and we were off to the races! Zero issues feeding or clogging and it flows so nicely. I would highly recommend this simple upgrade.

Its good
