0.4mm Centauri Carbon Hotend Kit with 3 Replacement Brass Nozzles, Ceramic Print Head Extruder Hot End for Elegoo 3D Printer Replacement Parts

Great add to your printing functionality is just like expected durability is a plus when paired with hardened tips as I did all in all great product.

Plug and play. Great replacement for the price and it's reliable.

I installed this ceramic hotend kit on my Elegoo Centauri Carbon four days ago, hoping for an easy upgrade. The package includes the pre-assembled print head and three spare brass nozzles, which seemed convenient. Right from the first print attempt, the nozzle refused to heat. The temperature reading stayed at room temperature no matter how long I waited. After pulling the hotend apart to troubleshoot, I found the real problem: the heating cartridge wires were barely soldered, just a couple of weak blobs of solder that had cracked and lost continuity. One gentle tug and the wire came right off. Clearly a defective unit that somehow passed whatever quality check exists. Since my stock hotend was still perfectly fine, I swapped everything back and the printer worked again immediately. The replacement took maybe twenty minutes total, but the whole experience wasted an evening and left me with a part I can’t trust. I’ve swapped hotends on several printers over the years and have never seen soldering this poor on a ready-to-install assembly. For something that operates at hundreds of degrees and carries current right next to plastic components, that kind of flaw is unacceptable. Until the manufacturer improves quality control, I’d stay away from this kit. The idea of a drop-in ceramic hotend for the Centauri Carbon is appealing, but this particular product isn’t ready for actual use. It's a bad value for the money since it's just not working. PS: Some might want me to address these subjects so I'm putting them here. This product has no effect on the noise level, no effect on the layer adhesion, no effect on the print quality, because you can't get any of those things from a non-functional unit.

This 0.4mm ceramic hotend kit works great and has excellent functionality right out of the box. The print quality is noticeably better and more consistent, and it handles filament smoothly without issues. It also feels solid and durable, making it a reliable upgrade for my Elegoo printer. Overall, it’s a simple install that delivers great results..

I installed this hotend on my Centauri Carbon 3D printer and the process was quick and straightforward. It matched the stock hotend closely in overall design, so there were no surprises during installation. I will say it has some clear material differences between the stock hotend, this one is definitely different in appearance and seems not quite as nice. However everything lined up properly and it dropped in without needing any modifications. After installing it, print quality has been good. I have been getting consistent layers, consistent extrusion, and reliable performance across multiple prints. It behaves for the most part like the original hotend, which is exactly what I was hoping for, and it has been producing some good results The kit includes additional nozzles, but I have not felt the need to install them yet since the original included nozzle has been printing decently for quite some time now. Based on how it has performed so far, I imagine this hotend will last a long while for most users. Overall, it feels like a good value.

I’m going to break this review into two parts: first I’ll consider the replacement nozzles and then I’ll discuss the hot end assembly. I recently acquired Centauri Carbon and while the need to replace the nozzle is still (hopefully) a long ways off, I’ve begun collecting nozzles so I’ll have them on hand when that day comes. Thus far, I’ve acquired nozzles from three different brands and I did a side-by-side inspection of each. The diameter of the bore/filament path/hole into which the filament _enters_ the nozzle seemed a tad narrower¹ than on the two other brands. The inside was smooth (unlike one brand, where I could clearly see tooling marks). I tested the filament path’s resistance by inserting (and rapidly moving back-and-forth) two different PLA filaments—a “silk” type with a very smooth surfaced, and a “tiny glitter particles” type with a rough surface. There was a tad more friction than the other brand with a smooth bore, a tad less friction than the brand with tool marks inside the bore. The nozzle is made of brass, with a hardened steel tip, and thus should hold up better to abrasive filaments (e.g., carbon fiber, glow in the dark, &c.) than a solid brass nozzle. The hole on the tip is circular. The threads look neatly cut. On to the hot end assembly. As my CC “ain’t broke,” I’m not (yet) going to try to fix it. I notice a couple other reviewers were unhappy with what they got. One reported poorly soldered sires, but the wires on mine look fine. Another said theirs arrived slightly bent, but mine is fine. If, when the day comes that I need to install it, I have any issues, I’ll update this review accordingly. But for now, I’m quite happy with this kit. _____ ¹ — I’m too new to 3D printing to know whether a slightly looser bore or a slightly tighter bore is best and a several web search didn’t turn up an answer to that question. Seems like a tighter bore would have more friction (which could be bad), but do a better job transferring heat to the filament (which could be good).

Direct replacement item for the Elegoo CC printer. Bimetal replacement tips of diffeerent nozzle sizes allow for flexibility in printing - with this printer its easier and to just maintain multiple hot ends with the sizes you like (for me it's .4 and .6) and just swap them out - 2 screws and 2 rather fiddly wire connectors - and you are back to printing.

This ceramic hotend is a noticeable improvement over the stock Centauri Carbon setup. It heats evenly, maintains consistent temperature, and produces cleaner extrusion with fewer clogs. The quick-detach system is a huge time-saver — swapping nozzles is effortless. The included brass nozzles are a nice bonus. If you’re running higher-temp filaments or want more durable, reliable prints, this is a solid upgrade for the Elegoo Centauri line.

I installed this on my Centauri Carbon yesterday and during its first print it basically exploded, knocking the print head cover off the machine and producing a huge bubble of filament. It was attached properly and the nozzle was secure. I have hundred of hours of printing on multple machines and have swapped the hot ends, so it was not user error, just a defective product. Now I'm left with a ruined nozzle, hotend and a lot of wasted filament.
