PLA poor quality prints

[Brzozar2 0]

Hello,

 

I have recently noticed that my PLA Prints are poorly printed on the Ultimaker S5. 

I have used a 0.2 and 0.15mm prints settings , 0,4mm Print Core.

Any ideas why the last few layers are sort of smeared/blurry?

Please see attached photos.

Thanks in advance for your help.

Could it be that: or you forgot to enable retraction, and/or you are printing too small items way too hot, so they have no time to cool?

Hi geert_2,

 

Thank you for your reply.

I have changed the layer thickness to the 0.1mm and these objects printed fine this time.

I guess I'll stay with this layer height for this particular part for now.

 

Thanks again.
