Cheap China Nozzles

[neotko 1,417]

Hi,

There's always people asking why shouldn't they use a cheap nozzle. We always answer with 'bad' quality, 'problems'. But I think that the final user never visualize the real problem.

They might look perfect outside. Even the nozzle hole might be perfect (more like it isnt but let's give them credit).

The problem it's most of the time where you can't see it. And that's why it's better an image than a lot of words.

The ones on the left are atomic pulls (mind that on 1.75 the atomics look different). And right are e3d nozzles.

So you see that flatness on the tip? That's the difference between a bad nozzle and an ok one. The filament will build there, stay on the flat sides and burn over time making a nice clog. But also you will need to print hotter than needed to actually print.

Can they work? Yes, if you don't care about problems and quality.

Nice review !

Did you test specifically one brand or more ?

Just 3 different 0.8-0.6 and one 0.4 from the cholsson hotend. It was really tempting since the outside look was quite ok. I tested that ones using faber and woodfill. Wood was really ok since it was 0.6 but also did clog badly after 4h. Luckily the e3d order arrived on time.
