Nozzle wear
Good morning everyone,
What are the signs of a worn nozzle? How do you know when to change it?

If you are only printing PLA then it should not be an issue. If you switch to abrasive filaments like carbon fiber / metal it can destroy the brass nozzle after just one print.

The question remains... 😉 😎

Well, true but it does not answer any of the two questions in the post.
Re: Nozzle wear
I have not had one wear out yet, but from what I read on the 3D groups you will not be able to print in fine detail. I think because the nozzle hole is an uniform circle.
Maybe a test is to print a single line circle? Was the first line uniform? If the nozzle wears out and the opening is no longer a circle, parts of the 1st layer would be fatter, but I am just guessing.
For example, once the nozzle is worn, I bet you would not be able to print this moving part:

Thanks David,
So you are saying precision will be lost, and I would tend to agree especially if the nozzle tip geometry is severely affected.
I found this document, with nice clear pictures of worn nozzles and explanations:

Thanks for the link, it was very informative and makes sense.
