Cheap China Nozzles

Recommended Posts

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.

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.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
