Not fit for Ender 3s1

This is a requisite upgrade if you are looking to use high-temp filaments such as PETG or ABS. I also think this is a nice upgrade, in general, if you are looking to improve heat transfer between the block and heating element (e.g., higher/faster nozzle temps). Materials and construction appear robust, and I have no question that this a genuine Creality part. It also comes from a reputable Creality reseller. This is relatively plug and play, making it perfect as a replacement part or upgrade!

I love these nozzles for PLA and PETG, but for some reason I could not get them to print TPU well. I did a PID tune, but there must be something with their heat conduction that flexible filaments didnt like. I tried them with NinjaTek and Amazon Basics TPU. Both were a no go. Ill still buy them though. They are fantastic with rigid filaments

On visual inspection, these nozzles appear flawless. So far Ive tried the 0.6mm size, and it has given really good results with more consistent lines than I had been getting with a 0.4mm nozzle. Unfortunately my extruder doesnt seem to be up to the task of cranking up the speed as some people do with the wider nozzles. The listing mentions V2, which I read to mean Ender 3 V2, but the silicone socks do not fit the stock extruder on my Ender 3 V2. Not a problem for me as I dont need a new sock, but worth noting for anyone who does and has the E3V2.

Not an exact copy of the heater block that came on my S1 (not pro) but it fits perfectly. Screws are slightly different, so use the ones that come with the kit. I do like that the thermistor is held in with a set screw instead of the big pan-head phillips screw that came standard.

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.

This Sprite hot end is a Great deal if your looking to upgrade from your stock hot end and extruded, I am newer to 3d printing and install was similar to a brick build follow the instructions one step at a time and you will be fine, be cautious of how the piece lines up on your machine, one bolt on the carrier may need to be reversed or adjusted to prevent colliding with the z axis. I personally had to print a mount to move the CR touch I installed to the back towards the x axis rail. But that part stl. is available if you look online. Very pleased with the first print results!! Worth the investment so far! Pay attention to how everything lines up and where your Cr or Bl touch is sitting vs your print bed!

For printing materials beyond PLA you might need a hot end capable of higher temperatures and this does it both efficiently and at a reasonable cost. Great retro fit for Creality printers others may need some leads soldered as well as changes to software that allow for temperatures as high as 300 C. Nice bi-metal hot end that keeps temperatures reasonable above the hot end.

This came with every nozzle size I could possibly need. I got two regular nozzles to replace my old ones, one to do finer prints, and two to do larger prints. It also came with new sleeves which is great to have. They do break over time so this is the perfect replacement solution. Im getting ready to print a large helmet so the 0.6 will come in really handy. I have already used the .4 and it works great!

I had to return these. There are several threads online that outline the issues with heat control and material feed. Unfortunately I cannot recommend these.
