1.75mm CR-10 3D Printer With Titanium Alloy Hotend Extruder Kit For 0.4mm Nozzle

Exterior finish was poor on the item I received with machining marks still evident, so no finishing on the exterior. After installing (Ender 3, using Rigid Ink PLA), for the first couple of minutes it printed well, then jammed. I was able to retract the filament and clear the jam, there was no evidence of heat creap. So fed the filament back in and again for the first few minutes it printed well, then jammed again. This time I was unable to retract the filament and had to disassemble the print head. Filament was jammed in the heartbreak, which on inspection was very rough preventing the smooth movement of the filament.As alway Amazon fixed the problem and refunded the cost of item.

So I got this as a cheap spare extruder because I was having problems with my TriangleLabs E3D V6 replication extruderLuckily my extruder started working well, so I've set this up on its own carriage with intention of it being a quick swap direct drive so I can easily swap between Bowden and Direct driveI'll admit, straight out of the box, it looked a little bit roughIt's machined accurately as I measured it against a Creality dimensioned carriage, and it fitted pretty wellHowever in terms of finishing, it is not particularly good, it had sharp edges, one of which I cut myself on whilst trying to put it on a carriageAs far as I can tell, it has a full metal throat that seems to be pretty goodThe printing, brief tests I did, but I didn't use it much other than print a few cogs, because I haven't had time to tune it in and calibrate properly, were pretty goodThe photo shows the Cog I printed using it before I swapped back to my Bowden because I wanted some faster printing for a very large printI wouldn't say I'm stunned, but anyone who's buying a cheap replica probably is wanting to save money and will appreciate that means there is some trade offOverall, in fairly happy because it prints well but mainly because I've got a good setup on a custom built setup with full metal frame and lead screw and gear movement as opposed to linear railI've not got a Creality printer so I can't comment companies we to an official Creality ExtruderI've not had many issues yet, but disclaimer that I haven't used it extensively yet...I saw some reviews saying that it had some issues, and I figured I go for it because it's easier to return to Amazon than China and because I knew I wasn't going to be using it much other than for some technical prints, I figured it wasn't worth investing heavily in something I was only going to dabble in for the time beingOverall it seems alright, the build quality is alright but finishing is pretty rough and readyBut, it seems to print alright and I've not had any clogged nozzles yet so....no complaints about thatBut I would like to emphasize I've only printed for around 5 hours worth of prints on this so far, so that's by no means a definitive test and if there are reviews claiming they've used it longer with their experiences, mine doesn't outweigh there's because I've used it so little so far, I'm skeptical of saying it's amazing or even good because I've not really used it muchI'll update this after I've got a few hundred hours printijg on it with my actual worn in views

Very poor. Not worth it, after install it started to leak and no matter how many times I clean and re install it. It would still happen.

All the metal pieces come apart easily.The finish of the product is good.Reassembly with a length of 1.75mm filament to ensure the alignment is straight.Comes with a good-sized .4mm brass end,A good fit onto the CR10. unit.

missing parts had to use some of my existing parts clogged up on first print
